Handlers#
The Application Framework implements all handlers, directly calling their associated callbacks. By default, Connect projects declare such callbacks as stubs in flex-callbacks-stubs.c. Hence, to use an enabled Connect feature, applications should replace the stub with their own implementation of the associated callback (typically in flex-callbacks.c). See UG235.04 for more info.
This handler is invoked when the stack has completed sending a message.
This handler is invoked when a node of EMBER_MAC_MODE_DEVICE type or EMBER_MAC_MODE_SLEEPY_DEVICE type has completed sending a MAC frame.
This handler is invoked when a packet has been received from a node type other than EMBER_MAC_MODE_DEVICE or EMBER_MAC_MODE_SLEEPY_DEVICE.
This handler is invoked when a node of EMBER_MAC_MODE_DEVICE type or EMBER_MAC_MODE_SLEEPY_DEVICE has received a MAC frame.
Send a message to the passed destination short ID.
Create a MAC level frame and sends it to the passed destination. This API can only be used for nodes of EMBER_MAC_MODE_DEVICE node type or EMBER_MAC_MODE_SLEEPY_DEVICE node type.
Send a data request command to the parent node. Note that if the node short ID is a value of EMBER_USE_LONG_ADDRESS, the node shall use its long ID as source address.
Set data polls destination address for nodes of EMBER_MAC_MODE_DEVICE node type or EMBER_MAC_MODE_SLEEPY_DEVICE node type.
Purge all indirect transmissions from the indirect message queue.
Set indirect queue timeout value. The indirect queue timeout is set by default to EMBER_INDIRECT_TRANSMISSION_TIMEOUT_MS.
Return the maximum payload according to the passed source and destination addressing modes, the passed secured flag, and the current configuration of the node.
Indicates if the stack is currently using long messages or not.
Set the current message length that the stack uses.

EmberStatus emberMessageSend (EmberNodeId destination, uint8_t endpoint, uint8_t messageTag, EmberMessageLength messageLength, uint8_t * message, EmberMessageOptions options)
Send a message to the passed destination short ID.
| [in] | destination | The destination node short ID. |
| [in] | endpoint | The destination endpoint of the outgoing message. This value can't exceed EMBER_MAX_ENDPOINT. |
| [in] | messageTag | A value chosen by the application. This value will be passed in the corresponding emberMessageSentHandler() call. |

| [in] | options | Specifies the EmberMessageOptions for the outgoing message. |
Returns
an EmberStatus value of:
EMBER_SUCCESS if the message was accepted by the stack. If a success status is returned, the emberMessageSentHandler() callback is invoked by the stack to indicate whether the message was successfully delivered or the reason for failure.

EMBER_MAC_UNKNOWN_DESTINATION if the node is part of a star network and the destination node does not appear in the node's routing table.
EMBER_MAC_SECURITY_NOT_SUPPORTED if the message was requested to be sent out secured and either the local node does not support security or the destination node is known to not support security.
EMBER_MAC_BUSY if the message was not accepted because the MAC is currently performing some critical operation.

EmberStatus emberMacMessageSend (EmberMacFrame * macFrame, uint8_t messageTag, EmberMessageLength messageLength, uint8_t * message, EmberMessageOptions options)

Note that if the source/destination PAN ID is not specified, it defaults to the node's PAN ID. Also, the destination address mode must be either EMBER_MAC_ADDRESS_MODE_SHORT or EMBER_MAC_ADDRESS_MODE_LONG. |
| [in] | messageTag | A value chosen by the application. This value will be passed in the corresponding emberMacMessageSentHandler() call. |

EMBER_INVALID_CALL if the node is of a node type other than EMBER_MAC_MODE_DEVICE or EMBER_MAC_MODE_SLEEPY_DEVICE.
EMBER_BAD_ARGUMENT if the packet length is 0, the passed TX options indicates some feature that is not supported or the destination address mode is set to EMBER_MAC_ADDRESS_MODE_NONE.
EMBER_MESSAGE_TOO_LONG if the message does not fit in a single frame.
EMBER_PHY_TX_BUSY if the message cannot be sent since the node does not support MAC queuing and the radio is currently busy.
EMBER_MAC_TRANSMIT_QUEUE_FULL if the outgoing MAC queue is currently full.

Set the current message length that the stack uses.
| [in] | useLongMessages | True to use long messages (length stored in a uint16_t), false to use short messages (length stored in a uint8_t). |
Note
This API is here to assure retro compatibility with old NCP Host lib versions. In NCP Host lib versions that do not support OFDM features (v1.1 and older), only short messaging is supported. For the NCP, short messages are used by default. The Host lib needs to call this API with useLongMessages set to true if it supports OFDM.
Warnings
This API changes the behavior of the Connect Serialization Protocol. It only has effect when using a RTOS or the NCP. Changing it may result in packets being incorrectly transfered through CSP when using a SUN-OFDM or SUN-FSK PHY.
