BACnetStack_ResetForeignDeviceTable

bool BACnetStack_ResetForeignDeviceTable();

Clears the router’s foreign device table.

Any foreign devices previously in the table will need to re-register with the BBMD. With more than one BACnet/IP Network Port, the foreign device table of every BACnet/IP data link is cleared.

Note

Requires the STACK_OPTION_NM_BBMDC (with STACK_OPTION_DATA_LINK_LAYER_IPV4 and STACK_OPTION_OBJECT_TYPE_NETWORK_PORT) build option (it turns on STACK_OPTION_BVLL_BBMD, the macro this function checks).

BACnet reference: ANSI/ASHRAE 135-2024 Annex J: J.5.2.1 (Foreign Device Table).

Returns

True if successfully cleared, otherwise false.
