Macros |
|
| #define | EMBER_API_MAJOR_VERSION 2 |
|
The major version number of the Ember stack release that the application is built against.
|
|
| #define | EMBER_API_MINOR_VERSION 0 |
|
The minor version number of the Ember stack release that the application is built against.
|
|
| #define | EMBER_STACK_PROFILE 0 |
|
Specifies the stack profile. The default is Profile 0.
|
|
| #define | EMBER_MAX_END_DEVICE_CHILDREN 6 |
|
The maximum number of end device children that a router will support. For profile 0 the default value is 6, for profile 1 the value is 14.
|
|
| #define | EMBER_SECURITY_LEVEL 5 |
|
The security level used for security at the MAC and network layers. The supported values are 0 (no security) and 5 (payload is encrypted and a four-byte MIC is used for authentication).
|
|
| #define | EMBER_CHILD_TABLE_SIZE EMBER_MAX_END_DEVICE_CHILDREN |
|
The maximum number of children that a node may have.
|
|
| #define | EMBER_KEY_TABLE_SIZE 0 |
|
The maximum number of link and master keys that a node can store,
not
including the Trust Center Link Key. The stack maintains special storage for the Trust Center Link Key.
|
|
| #define | EMBER_CERTIFICATE_TABLE_SIZE 0 |
|
The number of entries for the field upgradeable certificate table. Normally, certificates, such as SE certs, are stored in the runtime-unmodifiable MFG area. However, those devices wishing to add new certificates after manufacturing will have to use the normal token space. This defines the size of that table. For most devices 0 is appropriate since there is no need to change certificates in the field. For those wishing to field upgrade devices with new certificates, 1 is the correct size. Anything more is wasting SimEEPROM.
|
|
| #define | EMBER_MAX_DEPTH 15 |
|
The maximum depth of the tree in ZigBee 2006. This implicitly determines the maximum diameter of the network (
EMBER_MAX_HOPS
) if that value is not overridden.
|
|
| #define | EMBER_MAX_HOPS (2 * EMBER_MAX_DEPTH ) |
|
The maximum number of hops for a message.
|
|
| #define | EMBER_PACKET_BUFFER_COUNT 75 |
|
The number of Packet Buffers available to the Stack. The default is 75.
|
|
| #define | EMBER_MAX_NEIGHBOR_TABLE_SIZE 26 |
|
The maximum number of router neighbors the stack can keep track of.
|
|
| #define | EMBER_NEIGHBOR_TABLE_SIZE 16 |
| #define | EMBER_INDIRECT_TRANSMISSION_TIMEOUT 3000 |
|
The maximum amount of time (in milliseconds) that the MAC will hold a message for indirect transmission to a child.
|
|
| #define | EMBER_MAX_INDIRECT_TRANSMISSION_TIMEOUT 30000 |
| #define | EMBER_SEND_MULTICASTS_TO_SLEEPY_ADDRESS false |
|
Defines the behavior for the address that the multicasts are sent to. The normal address is RxOnWhenIdle=true (0xFFFD). However, setting this to true can change locally generated multicasts to be sent to the sleepy broadcast address (0xFFFF). Changing the default is NOT Zigbee Pro compliant and may not be inter-operable.
|
|
| #define | EMBER_END_DEVICE_POLL_TIMEOUT 5 |
|
The maximum amount of time, in units determined by
EMBER_END_DEVICE_POLL_TIMEOUT_SHIFT
, that an
EMBER_END_DEVICE
or
EMBER_SLEEPY_END_DEVICE
can wait between polls. The timeout value in seconds is
EMBER_END_DEVICE_POLL_TIMEOUT
<<
EMBER_END_DEVICE_POLL_TIMEOUT_SHIFT
. If no poll is heard within this time, the parent removes the end device from its tables.
|
|
| #define | EMBER_END_DEVICE_POLL_TIMEOUT_SHIFT 6 |
|
The units used for timing out end devices on their parents. See
EMBER_END_DEVICE_POLL_TIMEOUT
for an explanation of how this value is used.

and the subsequent callback to
emberMessageSentHandler()
.
|
|
| #define | EMBER_BINDING_TABLE_SIZE 0 |
|
The maximum number of bindings supported by the stack. The default is 0 bindings. Each binding consumes 2 bytes of RAM.
|
|
| #define | EMBER_ADDRESS_TABLE_SIZE 8 |
|
The maximum number of EUI64<->network address associations that the stack can maintain. The default value is 8.
|
|
| #define | EMBER_ROUTE_TABLE_SIZE 16 |
|
The maximum number of destinations to which a node can route messages. This include both messages originating at this node and those relayed for others. The default value is 16.
|
|
| #define | EMBER_DISCOVERY_TABLE_SIZE 8 |
|
The number of simultaneous route discoveries that a node will support.
|
|

|
|
| #define | EMBER_SOURCE_ROUTE_TABLE_SIZE 32 |
The maximum number of source route table entries supported by the utility code in
app/util/source-route.c
. The maximum source route table size is 255 entries, since a one-byte index is used, and the index 0xFF is reserved. The default value is 32.
|
|
| #define | EMBER_DEFAULT_BROADCAST_TABLE_SIZE 15 |
|
The maximum number of broadcasts during a single broadcast timeout period. The minimum and default value is 15 and can only be changed on compatible Ember stacks. Be very careful when changing the broadcast table size as it affects timing of the broadcasts and the number of possible broadcasts. Additionally, this value must be universal for all devices in the network. Otherwise, a single router can overwhelm all its neighbors with more broadcasts than they can support. In general, this value should be left alone.
|
|
| #define | EMBER_BROADCAST_TABLE_SIZE EMBER_DEFAULT_BROADCAST_TABLE_SIZE |
| #define | EMBER_RETRY_QUEUE_SIZE 16 |
| #define | EMBER_STORE_AND_FORWARD_QUEUE_SIZE 5 |

|
|
| #define | EMBER_FRAGMENT_MAX_WINDOW_SIZE 8 |
|

|
|
| #define | EMBER_FRAGMENT_WINDOW_SIZE 1 |
|
The number of blocks of a fragmented message that can be sent in a single window. The maximum is

| #define | EMBER_KEY_TABLE_TOKEN_SIZE EMBER_KEY_TABLE_SIZE |
| #define | EMBER_REQUEST_KEY_TIMEOUT 0 |
|
The length of time that the device will wait for an answer to its Application Key Request. For the Trust Center, this is the time it will hold the first request and wait for a second matching request. If both arrive within this time period, the Trust Center will reply to both with the new key. If both requests are not received, the Trust Center will discard the request. The time is in minutes, with the maximum time being 10 minutes. A value of 0 minutes indicates that the Trust Center will not buffer the request but instead respond immediately. Only 1 outstanding request is supported at a time.
|
|
| #define | EMBER_TRANSIENT_KEY_TIMEOUT_S (300) |
|
The length of time, in seconds, that a trust center will store a transient link key that a device can use to join its network. A transient key is added with a call to emberAddTransientLinkKey. After the transient key is added, it will be removed once this amount of time has passed. A joining device will not be able to use that key to join until it is added again on the trust center. The default value is 300 seconds, i.e., 5 minutes.
|
|
| #define | EMBER_END_DEVICE_BIND_TIMEOUT 60 |
|
The time the coordinator will wait (in seconds) for a second end device bind request to arrive. The default value is 60.
|
|
| #define | EMBER_PAN_ID_CONFLICT_REPORT_THRESHOLD 1 |
|
The number of PAN ID conflict reports that must be received by the network manager within one minute to trigger a PAN ID change. Very rarely, a corrupt beacon can pass the CRC check and trigger a false PAN id conflict. This is more likely to happen in very large dense networks. Setting this value to 2 or 3 dramatically reduces the chances of a spurious PAN ID change. The maximum value is 63. The default value is 1.
|
|
| #define | EMBER_TASK_COUNT (4) |
|
The number of event tasks that can be tracked for the purpose of processor idling. The Ember Zigbee Pro Stack requires a task, an application and associated libraries may use additional tasks, though typically no more than 4 are needed for most applications.
|
|
| #define | EMBER_MAX_SUPPORTED_NETWORKS 2 |
|
The number of networks supported by the stack.
|
|
| #define | EMBER_SUPPORTED_NETWORKS 1 |
| #define | EMBER_ZLL_GROUP_ADDRESSES 1 |
|
The number of unique group identifiers that this device requires.
|
|

Detailed Description
All configurations have defaults. Therefore, many applications may not need to do anything special. However, these defaults can be overridden by creating a CONFIGURATION_HEADER or within this header, defining the appropriate macro to a different size. For example, to reduce the number of allocated packet buffers from 24 (the default) to 8:
The convenience stubs provided in
config/ember-configuration.c
can be overridden by defining the appropriate macro and providing the corresponding callback function. For example, an application with custom debug channel input must implement
emberDebugHandler()
to process it. Along with the function definition, the application should provide the following line in its CONFIGURATION_HEADER:
See
ember-configuration-defaults.h
for source code.
Macro Definition Documentation
| #define EMBER_ADDRESS_TABLE_SIZE 8 |
The maximum number of EUI64<->network address associations that the stack can maintain. The default value is 8.
Address table entries are 10 bytes in size.
| #define EMBER_API_MAJOR_VERSION 2 |
The major version number of the Ember stack release that the application is built against.
| #define EMBER_API_MINOR_VERSION 0 |
The minor version number of the Ember stack release that the application is built against.
| #define EMBER_APS_UNICAST_MESSAGE_COUNT 10 |
The maximum number of APS retried messages that the stack can be transmitting at any time. Here, transmitting describes the time between the call to emberSendUnicast() and the subsequent callback to emberMessageSentHandler() .
- Note
- A message will typically use one packet buffer for the message header and one or more packet buffers for the payload. The default is 10 messages.
Each APS retried message consumes 6 bytes of RAM and two or more packet buffers.
| #define EMBER_ASSERT_SERIAL_PORT 1 |
Settings to control if and where assert information will be printed.
The output can be suppressed by defining
EMBER_ASSERT_OUTPUT_DISABLED
. The serial port to which the output is sent can be changed by defining
EMBER_ASSERT_SERIAL_PORT
as the desired port.
The default is to have the assert output on and sent to serial port 1.
| #define EMBER_BINDING_TABLE_SIZE 0 |
The maximum number of bindings supported by the stack. The default is 0 bindings. Each binding consumes 2 bytes of RAM.
| #define EMBER_BINDING_TABLE_TOKEN_SIZE EMBER_BINDING_TABLE_SIZE |
| #define EMBER_BROADCAST_TABLE_SIZE EMBER_DEFAULT_BROADCAST_TABLE_SIZE |
| #define EMBER_CERTIFICATE_TABLE_SIZE 0 |
The number of entries for the field upgradeable certificate table. Normally, certificates, such as SE certs, are stored in the runtime-unmodifiable MFG area. However, those devices wishing to add new certificates after manufacturing will have to use the normal token space. This defines the size of that table. For most devices 0 is appropriate since there is no need to change certificates in the field. For those wishing to field upgrade devices with new certificates, 1 is the correct size. Anything more is wasting SimEEPROM.
| #define EMBER_CHILD_TABLE_SIZE EMBER_MAX_END_DEVICE_CHILDREN |
The maximum number of children that a node may have.
For the mesh stack, this defaults to the value of EMBER_MAX_END_DEVICE_CHILDREN . In the mesh stack router children are not stored in the child table.
Each child table entry requires 4 bytes of RAM and a 10 byte token.
Application definitions for EMBER_CHILD_TABLE_SIZE that are larger than the default value are ignored and the default value used instead.
| #define EMBER_CHILD_TABLE_TOKEN_SIZE EMBER_CHILD_TABLE_SIZE |
| #define EMBER_DEFAULT_BROADCAST_TABLE_SIZE 15 |
The maximum number of broadcasts during a single broadcast timeout period. The minimum and default value is 15 and can only be changed on compatible Ember stacks. Be very careful when changing the broadcast table size as it affects timing of the broadcasts and the number of possible broadcasts. Additionally, this value must be universal for all devices in the network. Otherwise, a single router can overwhelm all its neighbors with more broadcasts than they can support. In general, this value should be left alone.
Broadcast table entries are 6 bytes in size.
| #define EMBER_DISCOVERY_TABLE_SIZE 8 |
The number of simultaneous route discoveries that a node will support.
Discovery table entries are 9 bytes in size.
| #define EMBER_END_DEVICE_BIND_TIMEOUT 60 |
The time the coordinator will wait (in seconds) for a second end device bind request to arrive. The default value is 60.
| #define EMBER_END_DEVICE_POLL_TIMEOUT 5 |
The maximum amount of time, in units determined by EMBER_END_DEVICE_POLL_TIMEOUT_SHIFT , that an EMBER_END_DEVICE or EMBER_SLEEPY_END_DEVICE can wait between polls. The timeout value in seconds is EMBER_END_DEVICE_POLL_TIMEOUT << EMBER_END_DEVICE_POLL_TIMEOUT_SHIFT . If no poll is heard within this time, the parent removes the end device from its tables.
Using the default values of both EMBER_END_DEVICE_POLL_TIMEOUT and EMBER_END_DEVICE_POLL_TIMEOUT_SHIFT results in a timeout of 320 seconds (just over five minutes). The maximum value for EMBER_END_DEVICE_POLL_TIMEOUT is 255.
| #define EMBER_END_DEVICE_POLL_TIMEOUT_SHIFT 6 |
The units used for timing out end devices on their parents. See EMBER_END_DEVICE_POLL_TIMEOUT for an explanation of how this value is used.
The default value of 6 means gives EMBER_END_DEVICE_POLL_TIMEOUT a default unit of 64 seconds (approximately one minute). The maximum value for EMBER_END_DEVICE_POLL_TIMEOUT_SHIFT is 14.

| #define EMBER_KEY_TABLE_SIZE 0 |
The maximum number of link and master keys that a node can store, not including the Trust Center Link Key. The stack maintains special storage for the Trust Center Link Key.
For the Trust Center, this controls how many totally unique Trust Center Link Keys may be stored. The rest of the devices in the network will use a global or hashed link key.
For normal nodes, this controls the number of Application Link Keys it can store. The Trust Center Link Key is stored separately from this table.

| #define EMBER_MAX_END_DEVICE_CHILDREN 6 |
The maximum number of end device children that a router will support. For profile 0 the default value is 6, for profile 1 the value is 14.
| #define EMBER_MAX_HOPS (2 * EMBER_MAX_DEPTH ) |
The maximum number of hops for a message.
The default maximum number of hops is two times the maximum depth ( EMBER_MAX_DEPTH ). This is the fallback value when the radius is not supplied by the Application (i.e., 0) or the stack is sending a message.
| #define EMBER_MAX_INDIRECT_TRANSMISSION_TIMEOUT 30000 |
| #define EMBER_MAX_NEIGHBOR_TABLE_SIZE 26 |
The maximum number of router neighbors the stack can keep track of.
A neighbor is a node within radio range. The maximum allowed value is 26. End device children are stored in the child table, not the neighbor table. The default is 16. Setting this value lower than 8 is not recommended.

If both arrive within this time period, the Trust Center will reply to both with the new key. If both requests are not received, the Trust Center will discard the request. The time is in minutes, with the maximum time being 10 minutes. A value of 0 minutes indicates that the Trust Center will not buffer the request but instead respond immediately. Only 1 outstanding request is supported at a time.
The Zigbee Pro Compliant value is 0.
| #define EMBER_RETRY_QUEUE_SIZE 16 |
| #define EMBER_ROUTE_TABLE_SIZE 16 |
