Function Documentation

void ptp_bmc ( )

Best master clock.

This function executes the BMC algorithm, this is not the standard algorithm specified on the IEC 61588/IEEE 1588 standard, it is an adaptation to PTP working on a ZigBee network with P2P where the master is always the parent node and the GrandMasterClock is the coordinator. If the port have no connection, the recommendation is to stay on listening state. IEC 61588-2009 / IEEE 1588-2008 9.3.1 b) doesn't describe the listening return value. IEC 61588-2009 / IEEE 1588-2008 9.2.6.8 and 9.3.1 b)
