Using bacnet stm32f10x routines, how to add MSTP_Slave_Node_FSM (I want to use automac

Question

I checked dlmstp.c in /port/stm32f10x and found that only master has no slave, because I need automac but there is no MSTP_Slave_Node_FSM in the process, what should I do.

I use device A (master) to send WhoIs to device B (slave), but device B fails to send I_AM

Answer 1

When sending a Who-IS message to a MSTP Slave device you need to address it specifically as a directed message instead of a broadcast message (0xFF).
