Macros |
|
| #define | EMBER_TASK_COUNT |
|
The number of event tasks that can be tracked for the purpose of processor idling.
More...
|
|
| #define | EMBER_HEAP_SIZE |
|
The size in bytes of the Ember heap.
More...
|
|
| #define | EMBER_CHILD_TABLE_SIZE |
|
The maximum number of children that a node may have set by default to 0. If the application includes the optional parent support stack feature, this should be adjusted accordingly.
More...
|
|
| #define | EMBER_CHILD_TABLE_TOKEN_SIZE |
| #define | EMBER_CHILD_TIMEOUT_SEC |
|
Every child should exchange regularly some sort of traffic with the parent. Eventually, if traffic is not exchanged for a prolonged period of time, the parent will remove the child from the child table. Range extenders periodically exchange network-level commands with the coordinator. End devices and sleepy end devices can use
emberPollForData()
as keep alive mechanism.

|
|
| #define | EMBER_INDIRECT_QUEUE_SIZE |
|
The maximum number of pending indirect packets set by default to 0. If the application includes the optional parent support stack feature, this should be adjusted accordingly.
More...
|
|
| #define | EMBER_MAC_OUTGOING_QUEUE_SIZE |
|
The maximum number of packets in the outgoing MAC queue set by default to 0. If the application includes the optional MAC queue stack feature, this should be adjusted accordingly.
More...
|
|
| #define | EMBER_INDIRECT_TRANSMISSION_TIMEOUT_MS |
|
The maximum amount of time (in milliseconds) that the MAC will hold a message for indirect transmission to a child.
More...
|
|
| #define | EMBER_MAX_INDIRECT_TRANSMISSION_TIMEOUT_MS |
| #define | EMBER_NWK_RANGE_EXTENDER_UPDATE_PERIOD_SEC |
|
The period in seconds a range extender sends an update command to the coordinator containing the list of its children.
More...
|
|
| #define | EMBER_MAC_ACK_TIMEOUT_MS |
|
The ACK timeout in milliseconds. This parameter should be fine-tuned to reduce energy consumption for sleepy devices and depends on the data rate of the PHY configuration used.
More...
|
|
| #define | EMBER_RADIO_CCA_THRESHOLD |
|
The CCA threshold used at the MAC layer.
More...
|
|
| #define | EMBER_FREQUENCY_HOPPING_SEED |
|
The frequency hopping channel sequence generation seed.
More...
|
|
| #define | EMBER_FREQUENCY_HOPPING_START_CHANNEL |
|
The lowest channel on the frequency hopping list.
More...
|
|
| #define | EMBER_FREQUENCY_HOPPING_END_CHANNEL |
|
The highest channel on the frequency hopping list.
More...
|
|
| #define | EMBER_FREQUENCY_HOPPING_CHANNEL_DURATION_MS |
|
The time in milliseconds to stay on each channel for frequency hopping.
More...
|
|
| #define | EMBER_FREQUENCY_HOPPING_CHANNEL_GUARD_DURATION_MS |
|
The time in milliseconds to guard each channel while frequency hopping. No MAC activity is allowed when entering or exiting the slot.
More...
|
|
| #define | EMBER_FREQUENCY_HOPPING_SERVER_FREQ_INFO_BROADCAST_PERIOD_S |
|
The duration in seconds after which the server should broadcast its frequency hopping information to allow clients to realign.
More...
|
|
| #define | EMBER_FREQUENCY_HOPPING_CLIENT_RESYNC_PERIOD_S |
|
The duration in seconds after which the client should resync with the server if the last resync happened more than this duration ago.

Detailed Description
All configurations have defaults. Therefore, many applications may not need to do anything special. However, you can override these defaults by creating a CONFIGURATION_HEADER and, within this header, defining the appropriate macro to a different size.
See
ember-configuration-defaults.h
for source code.
