Handlers#
Invoked if a beacon is received during the scanning procedure if the handler was initiated by the application with the emberStartActiveScan() stack APIs.
Invoked after the application calls the emberStartActiveScan() stack API to inform the application that the scanning procedure is complete.
Invoked after the application calls the emberStartEnergyScan() stack API to inform the application that the energy scan procedure is complete and to provide statistics.
Callbacks#
This stack handler is invoked after the application calls the emberFrequencyHoppingStartClient() stack API to inform the application that the synchronization process with the server is complete. See emberFrequencyHoppingStartClient() for details.
Macros#
The maximum length in bytes of the application beacon payload.
The length in bytes of the stack beacon payload.
The maximum length in bytes of the beacon fields (superframe, GTS, pending address) as per 802.15.4 specs.
A special timeout value that disables aging of the child table.
The maximum timeout in seconds after which a stale entry may be removed from the child table.
The maximum length in bytes of the join payload.
The maximum number of entries the auxiliary address filtering table can hold.
A special value for the frequency hopping non sleepy client timeout that disables synchronization loss detection.
Functions#
Initialize the radio and the Ember stack.
A periodic tick routine that should be called in the main loop in the application.
Resume the network operation after a reboot.
Start an active scan. EMBER_SUCCESS signals that the scan successfully started. Upon receiving a beacon, the emberIncomingBeaconHandler() stack handler is called. At the end of the scanning procedure, the emberActiveScanCompleteHandler() stack handler is called. Note that, while a scan can be initiated when the node is currently joined to a network, the node will generally be unable to communicate with its PAN during the scan period. In particular, time-sensitive network operations might be affected because a scan operation will prevent any network operation for the duration of the scan.
Set the time in milliseconds the node will spend listening for incoming beacons during an active scan. The default value is set based on the symbol time of the current PHY configuration according to the 802.15.4 specs.
Get the current active scan duration in milliseconds.
Start an energy scan. EMBER_SUCCESS signals that the scan successfully started. At the end of the scanning procedure, the emberEnergyScanCompleteHandler() stack handler is called. Note that, while a scan can be initiated when the node is currently joined to a network, the node is generally unable to communicate with its PAN during the scan period. In particular, time-sensitive network operations might be affected because a scan operation will prevent any network operation for the duration of the scan.
Allow the application to set the application portion of the beacon payload. It's by default set to the empty string.
Form a new network by becoming the coordinator. This API requires the parent-support library to be present.
Cause the stack to associate with the network using the specified network parameters. It can take several seconds for the stack to associate with the local network. Do not send messages until a call to the emberStackStatusHandler() callback informs you that the stack is up. Notice that forming a network causes the node's security frame counter to be reset.
Cause the stack to associate with the network using the specified network parameters. The network ID is assigned by the network coordinator. It can take several seconds for the stack to associate with the local network. Do not send messages until a call to the emberStackStatusHandler() callback informs you that the stack is up. Notice that joining a network causes the node's security frame counter to be reset.
Tell the stack to allow other nodes to join the network with this node as their parent. Joining is initially disabled by default. This function may only be called after the node is part of a network and the stack is up.
Cause the stack to go up with the passed network parameters without performing any over-the-air message exchange. Notice that commissioning a network causes the node's security frame counter to be reset.
When invoked at a EMBER_STAR_COORDINATOR or a EMBER_STAR_RANGE_EXTENDER, it causes the stack to only accept subsequent joining nodes with matching joining payload. When invoked at a node that has not yet joined a network, it sets the joining payload that will be included in the joining process. Notice, the join payload is included in a non-standard 802.15.4 command, therefore this feature is not available for nodes operating as EMBER_MAC_MODE_DEVICE or EMBER_MAC_MODE_SLEEPY_DEVICE.
Clear the join payload previously set with the emberSetSelectiveJoinPayload() API. When invoked at an EMBER_STAR_COORDINATOR or an EMBER_STAR_RANGE_EXTENDER it causes the stack to accept joining nodes with any join payload pattern. When invoked at a node that has not yet joined a network, it clears the join payload. Subsequent joining attempts will not include any join payload in the over-the-air joining handshake.
Set an entry in the auxiliary address filtering table at a given address. Nodes of EMBER_DIRECT_DEVICE device type can receive incoming messages destined to any of the node IDs in the auxiliary address filtering table (while also receiving messages destined to actual node ID). If the passed node ID is EMBER_NULL_NODE_ID, the entry is cleared.
Retrieve the content of the auxiliary address filtering table at a given address. See emberSetAuxiliaryAddressFilteringEntry() for details.
Forget the current network and reverts to a network status of EMBER_NO_NETWORK.
Form a new network as an EMBER_MAC_MODE_DEVICE by becoming the coordinator. This API should be used to form a compliant 802.15.4 PAN and to inter-operate with other 802.15.4 devices. Notice that forming a network causes the node's security frame counter to be reset.
Configure a EMBER_MAC_MODE_DEVICE node to be a PAN coordinator. Note, this only applies to nodes that have been commissioned as EMBER_MAC_MODE_DEVICE.
Return an EmberChildFlags bitmask indicating the child flags of the child corresponding to the passed MAC address.
Return info on the child corresponding to the passed MAC address.
Remove the node corresponding to the passed MAC address from the child table.
Allow a star topology node that previously joined a network to leave the network. The node will notify the parent node and eventually leave the network. The application is notified that the leave procedure completed via the emberStackStatusHandler() handler.
Populate the short-to-long address mapping table at the MAC layer. The table is meaningful only when running as EMBER_MAC_MODE_DEVICE or EMBER_MAC_MODE_SLEEPY_DEVICE. The standard 802.15.4 encryption and authentication process requires the security nonce to be populated with the source node long ID. A receiver must do the same to decrypt a secured incoming message. This short-to-long mapping table is used to decrypt a secured incoming packet from a node using short source addressing. If no entry is found in this table, the incoming message will be dropped. This table is also used to encrypt secured outgoing messages with short source addressing in case the node is sending out a secured message with a short source address other than its own.
Clear the short-to-long address mapping table at the MAC layer.
Set the MCS in case of an OFDM PHY. MCS can range from 0 to 6.
Get the MCS in case of an OFDM PHY.
Set the channel mask for frequency hopping. This API can only be invoked when the node is not frequency hopping.
Start the device operating as a frequency hopping server. This API can only be invoked when the node is joined to a network. Notice that the server upon starting hopping shall perform an initial advertisement across the entire channel hopping sequence. This is done to resynchronize clients in case the server was started as result of a reboot.
Start operating as a frequency hopping client and synchronize with the specified server. This API can be invoked on nodes that are already joined to a network (with the exception of nodes started as EMBER_MAC_MODE_DEVICE or EMBER_MAC_MODE_SLEEPY_DEVICE) and nodes that are not joined to a network yet. If the node is already performing frequency hopping, this API returns EMBER_INVALID_CALL. If this API returns EMBER_SUCCESS, the emberFrequencyHoppingStartClientCompleteHandler() is invoked asynchronously to inform the application whether the node successfully synchronized with the specified server or to inform the application of the reason of failure. After the client is synced to a server, it may seamlessly perform the resynchronization process if needed. Sleepy devices in particular periodically perform the resynchronization process. If the client fails a resynchronization process, it informs the application by invoking the emberStackStatusHandler() handler with EMBER_MAC_SYNC_TIMEOUT status. When this occurs, the client will no longer be synced to the server. The application may elect to attempt a new synchronization process by invoking this API again.
Stop frequency hopping. This API can only be invoked when the node is frequency hopping. Applicable for both server and client.

emberInit#
EmberStatus emberInit (void )
Initialize the radio and the Ember stack.
N/A |
Device configuration functions must be called before emberInit() is called.
Note
The application must check the return value of this function. If the initialization fails, normal messaging functions are not available. Some failure modes are not fatal, but the application must follow certain procedures to permit recovery. Ignoring the return code results in unpredictable radio and API behavior. (In particular, problems with association will occur.)
Returns

Resume the network operation after a reboot.
N/A |
This API must be called on boot prior to ANY network operations. It initializes the networking system and attempts to resume the previous network identity and configuration. If the node was not previously joined, this routine should still be called.
If the node was previously joined to a network, it will retain its original type (e.g., coordinator, router, end device, and so on.)
EMBER_NOT_JOINED is returned if the node is not part of a network.
Returns
An EmberStatus value that indicates one of the following:
successful initialization,
EMBER_NOT_JOINED if the node is not part of a network, or
the reason for failure.

emberStartActiveScan#
EmberStatus emberStartActiveScan (uint16_t channel)
Start an active scan. EMBER_SUCCESS signals that the scan successfully started. Upon receiving a beacon, the emberIncomingBeaconHandler() stack handler is called. At the end of the scanning procedure, the emberActiveScanCompleteHandler() stack handler is called. Note that, while a scan can be initiated when the node is currently joined to a network, the node will generally be unable to communicate with its PAN during the scan period. In particular, time-sensitive network operations might be affected because a scan operation will prevent any network operation for the duration of the scan.

emberStartEnergyScan#
EmberStatus emberStartEnergyScan (uint16_t channel, uint8_t samples)
Start an energy scan. EMBER_SUCCESS signals that the scan successfully started. At the end of the scanning procedure, the emberEnergyScanCompleteHandler() stack handler is called. Note that, while a scan can be initiated when the node is currently joined to a network, the node is generally unable to communicate with its PAN during the scan period. In particular, time-sensitive network operations might be affected because a scan operation will prevent any network operation for the duration of the scan.
[in] | channel | The channel to scan. |
[in] | samples | The number of energy samples to be produced. Each sample is performed averaging the detected energy over X symbols time, whereas X depends on the selected PHY configuration and set by default to 8. The symbol time duration also depends on the selected PHY configuration. |

emberJoinNetworkExtended#
EmberStatus emberJoinNetworkExtended (EmberNodeType nodeType, EmberNodeId nodeId, EmberNetworkParameters * parameters)
Cause the stack to associate with the network using the specified network parameters. It can take several seconds for the stack to associate with the local network. Do not send messages until a call to the emberStackStatusHandler() callback informs you that the stack is up. Notice that forming a network causes the node's security frame counter to be reset.
[in] | nodeType | Specification of the role that this node will have in the network. This role can be EMBER_STAR_RANGE_EXTENDER, EMBER_STAR_END_DEVICE, EMBER_STAR_SLEEPY_END_DEVICE, EMBER_MAC_MODE_DEVICE or EMBER_MAC_MODE_SLEEPY_DEVICE. If the node is frequency hopping, the role can not be EMBER_STAR_RANGE_EXTENDER. |
[in] | nodeId | An EmberNodeId value indicating the short ID the node intends to use for addressing purposes. If this value is EMBER_NULL_NODE_ID, the network coordinator will allocate a new short address. Addresses should be allocated by the coordinator unless there is a specific need to join a network with a specific ID. If a specific ID is used, uniqueness should be guaranteed across the entire network by the application, via some out of band means. Notice that nodes of EMBER_MAC_MODE_DEVICE or EMBER_MAC_MODE_SLEEPY_DEVICE require this parameter to be set to EMBER_NULL_NODE_ID. |
[in] | parameters | An EmberNetworkParameters value that specifies the network parameters of the network with which the node should associate. |
Returns
An EmberStatus value that indicates either:
that the association process began successfully or
the reason for failure.

It can take several seconds for the stack to associate with the local network. Do not send messages until a call to the emberStackStatusHandler() callback informs you that the stack is up. Notice that joining a network causes the node's security frame counter to be reset.
[in] | nodeType | Specification of the role that this node will have in the network. This role can be EMBER_STAR_RANGE_EXTENDER, EMBER_STAR_END_DEVICE, EMBER_STAR_SLEEPY_END_DEVICE, EMBER_MAC_MODE_DEVICE or EMBER_MAC_MODE_SLEEPY_DEVICE. If the node is frequency hopping, the role can not be EMBER_STAR_RANGE_EXTENDER. |

emberPermitJoining#
EmberStatus emberPermitJoining (uint8_t duration)
Tell the stack to allow other nodes to join the network with this node as their parent. Joining is initially disabled by default. This function may only be called after the node is part of a network and the stack is up.
[in] | duration | A value of 0x00 disables joining. A value of 0xFF enables joining indefinitely. Any other value enables joining for that number of seconds. |
Returns
an EmberStatus value of EMBER_SUCCESS if the permit joining was successfully set, otherwise an EmberStatus value indicating the reason of failure.

emberJoinCommissioned#
EmberStatus emberJoinCommissioned (EmberNodeType nodeType, EmberNodeId nodeId, EmberNetworkParameters * parameters)
Cause the stack to go up with the passed network parameters without performing any over-the-air message exchange. Notice that commissioning a network causes the node's security frame counter to be reset.
[in] | nodeType | Specifies the role that this node will have in the network. The only device types allowed in the commissioning API are EMBER_DIRECT_DEVICE, EMBER_MAC_MODE_DEVICE and EMBER_MAC_MODE_SLEEPY_DEVICE. |
[in] | nodeId | An EmberNodeId value that specifies the short ID the node will have. The passed node ID must be a valid short address (any value other than EMBER_NULL_NODE_ID or EMBER_BROADCAST_ADDRESS). A value of EMBER_USE_LONG_ADDRESS is allowed only when commissioning the node as EMBER_MAC_MODE_DEVICE or EMBER_MAC_MODE_SLEEPY_DEVICE and will cause the node to send MAC level control messages such as data polls or beacons using long source addressing. |
[in] | parameters | An EmberNetworkParameters value that specifies the network parameters of the network the node should participate in. |
Returns
An EmberStatus value that indicates either:
that the node successfully commissioned the passed network parameters
the reason for failure.

emberSetSelectiveJoinPayload#
EmberStatus emberSetSelectiveJoinPayload (uint8_t payloadLength, uint8_t * payload)
When invoked at a EMBER_STAR_COORDINATOR or a EMBER_STAR_RANGE_EXTENDER, it causes the stack to only accept subsequent joining nodes with matching joining payload. When invoked at a node that has not yet joined a network, it sets the joining payload that will be included in the joining process. Notice, the join payload is included in a non-standard 802.15.4 command, therefore this feature is not available for nodes operating as EMBER_MAC_MODE_DEVICE or EMBER_MAC_MODE_SLEEPY_DEVICE.
[in] | payloadLength | The length in bytes of the passed joining payload. This can not exceed EMBER_MAX_SELECTIVE_JOIN_PAYLOAD_LENGTH. |
[in] | payload | A pointer to the payload to be set. |
Returns
An EmberStatus value that indicates either:
that the node successfully set the join payload.
the reason for failure.

emberClearSelectiveJoinPayload#
EmberStatus emberClearSelectiveJoinPayload (void )
Clear the join payload previously set with the emberSetSelectiveJoinPayload() API. When invoked at an EMBER_STAR_COORDINATOR or an EMBER_STAR_RANGE_EXTENDER it causes the stack to accept joining nodes with any join payload pattern. When invoked at a node that has not yet joined a network, it clears the join payload. Subsequent joining attempts will not include any join payload in the over-the-air joining handshake.
N/A |
Returns
An EmberStatus value that indicates either:
that the node successfully cleared the join payload.
the reason for failure.

emberSetAuxiliaryAddressFilteringEntry#
EmberStatus emberSetAuxiliaryAddressFilteringEntry (EmberNodeId nodeId, uint8_t entryIndex)
Set an entry in the auxiliary address filtering table at a given address. Nodes of EMBER_DIRECT_DEVICE device type can receive incoming messages destined to any of the node IDs in the auxiliary address filtering table (while also receiving messages destined to actual node ID). If the passed node ID is EMBER_NULL_NODE_ID, the entry is cleared.
[in] | nodeId | An EmberNodeId value to be added to the auxiliary address filtering table at the passed entry index. |
[in] | entryIndex | The index of the auxiliary address filtering table entry to be set. |

emberMacFormNetwork#
EmberStatus emberMacFormNetwork (EmberNetworkParameters * parameters)
Form a new network as an EMBER_MAC_MODE_DEVICE by becoming the coordinator. This API should be used to form a compliant 802.15.4 PAN and to inter-operate with other 802.15.4 devices. Notice that forming a network causes the node's security frame counter to be reset.
[in] | parameters | An EmberNetworkParameters value that specifies the network parameters of the network to be formed. |
Returns
An EmberStatus value that indicates either the successful formation of the new network or the reason that the network formation failed.

of file /mnt/raid/workspaces/ws.2dqDELv9z/overlay/gsdk/protocol/flex/stack/include/network-management.h
emberGetChildInfo#
EmberStatus emberGetChildInfo (EmberMacAddress * address, EmberMacAddress * addressResp, EmberChildFlags * flags)
Return info on the child corresponding to the passed MAC address.
[in] | address | A pointer to an EmberMacAddress that specifies the MAC address of the child (short or long). |
[out] | addressResp | A pointer to an EmberMacAddress that returns the other address (respectively long or short). |
[out] | flags | A pointer to an EmberChildFlags containing the child flags of the child corresponding to the passed MAC address. |
Note
For star coordinators, if the input address is short, the corresponding child will also be searched in the list of devices connected through range extender. Long address and additional flags for these devices are not available to the coordinator.
Note
Both out parameters are optional. If set to NULL, the API will at least indicate if the child was found in the network.
Returns
An EmberStatus value of EMBER_SUCCESS if the child was found in the child table, EMBER_CHILD_NOT_FOUND if it was not, or another EmberStatus value indicating the reason of failure.

emberMacAddShortToLongAddressMapping#
EmberStatus emberMacAddShortToLongAddressMapping (EmberNodeId shortId, EmberEUI64 longId)
Populate the short-to-long address mapping table at the MAC layer. The table is meaningful only when running as EMBER_MAC_MODE_DEVICE or EMBER_MAC_MODE_SLEEPY_DEVICE. The standard 802.15.4 encryption and authentication process requires the security nonce to be populated with the source node long ID. A receiver must do the same to decrypt a secured incoming message. This short-to-long mapping table is used to decrypt a secured incoming packet from a node using short source addressing. If no entry is found in this table, the incoming message will be dropped. This table is also used to encrypt secured outgoing messages with short source addressing in case the node is sending out a secured message with a short source address other than its own.
[in] | shortId | The short address of the [short, long] entry to be added to the table. |
[in] | longId | The long address of the [short, long] entry to be added to the table. |
Note
Because the table is stored in RAM, the application should ensure it gets correctly re-populated upon reboot.
Adding a new entry will cause the removal of existing entries matching the passed short ID or long ID.
Returns
an EmberStatus value of:
EMBER_SUCCESS if the mapping was successfully added to the table.
EMBER_INVALID_CALL if the node is not running as EMBER_MAC_MODE_DEVICE or as EMBER_MAC_MODE_SLEEPY_DEVICE.
EMBER_TABLE_FULL if the table is currently full.
EMBER_NO_BUFFERS if the heap does not currently have enough space for the new entry. The size of the table is controlled by the EMBER_SECURITY_SHORT_TO_LONG_MAPPING_TABLE_SIZE.

emberFrequencyHoppingSetChannelMask#
EmberStatus emberFrequencyHoppingSetChannelMask (uint8_t channelMaskLength, uint8_t * channelMask)
Set the channel mask for frequency hopping. This API can only be invoked when the node is not frequency hopping.
[in] | channelMaskLength | Length of the bitmap in bytes |
[in] | channelMask | A pointer to a bitmap representing allowed channels for frequency hopping. |
Note
The application is responsible for applying this setting to both the server and clients.
Note
The bitmap size needs to be at least (EMBER_FREQUENCY_HOPPING_END_CHANNEL + 8) >> 3 or an error is thrown.
The bitmap needs to be set again after stopping frequency hopping.
Returns
An EmberStatus value of EMBER_SUCCESS if the node successfully set the bitmask. An EmberStatus value of EMBER_INVALID_CALL if the node is currently performing frequency hopping. An EmberStatus value of EMBER_BAD_ARGUMENT if the resulting channel list is empty, or if channelMaskLength is shorter than expected.

of file /mnt/raid/workspaces/ws.2dqDELv9z/overlay/gsdk/protocol/flex/stack/include/network-management.h
emberFrequencyHoppingStartServer#
EmberStatus emberFrequencyHoppingStartServer (void )
Start the device operating as a frequency hopping server. This API can only be invoked when the node is joined to a network. Notice that the server upon starting hopping shall perform an initial advertisement across the entire channel hopping sequence. This is done to resynchronize clients in case the server was started as result of a reboot.
N/A |
Returns
An EmberStatus value of EMBER_SUCCESS if the node successfully initiated frequency hopping server operations. An EmberStatus value of EMBER_INVALID_CALL if the node is not currently joined to a network or if the node is already performing frequency hopping.

emberFrequencyHoppingStartClient#
EmberStatus emberFrequencyHoppingStartClient (EmberNodeId serverNodeId, EmberPanId serverPanId)
Start operating as a frequency hopping client and synchronize with the specified server. This API can be invoked on nodes that are already joined to a network (with the exception of nodes started as EMBER_MAC_MODE_DEVICE or EMBER_MAC_MODE_SLEEPY_DEVICE) and nodes that are not joined to a network yet. If the node is already performing frequency hopping, this API returns EMBER_INVALID_CALL. If this API returns EMBER_SUCCESS, the emberFrequencyHoppingStartClientCompleteHandler() is invoked asynchronously to inform the application whether the node successfully synchronized with the specified server or to inform the application of the reason of failure. After the client is synced to a server, it may seamlessly perform the resynchronization process if needed. Sleepy devices in particular periodically perform the resynchronization process. If the client fails a resynchronization process, it informs the application by invoking the emberStackStatusHandler() handler with EMBER_MAC_SYNC_TIMEOUT status. When this occurs, the client will no longer be synced to the server. The application may elect to attempt a new synchronization process by invoking this API again.
[in] | serverNodeId | An EmberNodeId value indicating the node ID of the server to synchronize with. |
[in] | serverPanId | An EmberPanId value indicating the PAN ID of the server to synchronize with. Note that this parameter is meaningful only if the node is not currently joined to any network. |
Returns
An EmberStatus value of EMBER_SUCCESS indicating that the node successfully initiated the synchronization process with the server, otherwise an EmberStatus value indicating the reason of failure.

emberFrequencyHoppingStop#
EmberStatus emberFrequencyHoppingStop (void )
Stop frequency hopping. This API can only be invoked when the node is frequency hopping. Applicable for both server and client.
N/A |
Returns
An EmberStatus value of EMBER_SUCCESS indicating that the node successfully stopped frequency hopping. An EmberStatus value of EMBER_INVALID_CALL if the node is not currently frequency hopping.
