Network Configurations

Changing Stack Parameters

The following is a collection of some significant definitions to be considered when designing a Zigbee mesh network. Keep in mind that this is not a c omprehensive list. More information can be found in the “Compile-time configuration parameters” section of the ZBOSS User’s Guide.

Note

Be sure to perform a clean build (Project → Clean) after configuring a parameter to ensure that the changes take effect.

Zigbee Device

Location: <sdk_directory>\source\third_party\zigbee\zboss_r23\include\zb_config.h

  • ZB_ZDO_PARENT_LINK_FAILURE_CNT: Maximum retries for an end device not receiving ACKs

Location: <sdk_directory>\source\third_party\zigbee\zboss_r23\include\zb_config_common.h

  • ZB_N_APS_MAX_FRAME_RETRIES: Maximum number of APS layer retries after a missed APS ACK

  • ZB_N_APS_ACK_WAIT_DURATION_FROM_SLEEP: APS ACK wait time from sleepy devices

  • ZB_MAC_MAX_FRAME_RETRIES: Maximum number of MAC frame transmission retries

  • ZB_STANDARD_TC_KEY: Pre-configured Trust Center link key and must remain as default for Zigbee Alliance 3.x compliance

  • ZB_NWK_LINK_STATUS_PERIOD: Interval for which link status reports are broadcast on the network

  • ZB_DEFAULT_MAX_CHILDREN: Maximum number of children which can join to this device

  • ZB_BDBC_TCLINK_KEY_EXCHANGE_TIMEOUT: Timeout in seconds for the Trust Center to exchange link keys with the newly joined node

  • ZB_BDBC_MIN_COMMISSIONING_TIME_S: Minumum commissioning period

Location: <sdk_directory>\source\third_party\zigbee\zboss_r23\include\zb_mem_config_common.h

  • ZB_CONFIG_NWK_ROUTING_TABLE_SIZE: Maximum number of AODV routing entries

  • ZB_CONFIG_NWK_MAX_SOURCE_ROUTES: Number of cached source routes, coordinator MTO-routing specific and should equal the max number of nodes in the the network

  • ZB_CONFIG_NEIGHBOR_TABLE_SIZE: Number of neighbors supported by the neighbor table

  • ZB_CONFIG_OVERALL_NETWORK_SIZE: Maximum network size

Location: Project output folder → default/syscfg/ti_zigbee_config.h

  • DEFAULT_CHANLIST: Set of 2.4-GHz channels that the Zigbee device will first attempt to operate on
