General constants

The table below lists the ZigBee Base Device constants that can be used on all nodes and also shows the corresponding macros used to define the constant values in the bdb_options.h file.

Table: ZBD General Constants and Macros

Constant	Macro
bdbcMaxSameNetworkRetryAttempts	BDBC_MAX_SAME_NETWORK_RETRY_ATTEMPTS
bdbcMinCommissioningTime	BDBC_MIN_COMMISSIONING_TIME
bdbcRecSameNetworkRetryAttempts	BDBC_REC_SAME_NETWORK_RETRY_ATTEMPTS
bdbcTCLinkKeyExchangeTimeout	BDBC_TC_LINK_KEY_EXCHANGE_TIMEOUT

bdbcMaxSameNetworkRetryAttempts

This constant specifies the maximum number of join or key exchange attempts that the node can make on the same network. The value of this constant is defined using the macro BDBC_MAX_SAME_NETWORK_RETRY_ATTEMPTS and should be set to 10 (as recommended in the ZigBee BDB Specification).

bdbcMinCommissioningTime

This constant specifies the minimum time-interval (in seconds) for which a network is open to allow new nodes to join or for a device to identify itself. The value of this constant is defined using the macro BDBC_MIN_COMMISSIONING_TIME and should be set to 180 (as recommended in the ZigBee BDB Specification).

bdbcRecSameNetworkRetryAttempts

This constant specifies the recommended number of join or key exchange attempts that the node can make on the same network. The value of this constant is defined using the macro BDBC_REC_SAME_NETWORK_RETRY_ATTEMPTS and should be set to 3 (as recommended in the ZigBee BDB Specification).

bdbcTCLinkKeyExchangeTimeout

This constant specifies the maximum time (in seconds) for which a joining node will wait for a response after an APS key request has been sent to the Trust Centre. The value of this constant is defined using the macro BDBC_TC_LINK_KEY_EXCHANGE_TIMEOUT and should be set to 5 (as recommended in the ZigBee BDB Specification).
