If wifi transmission coincides with other events on our system, too much current is drawn. (Changing the power supply is not an option). Is there a way to place a mutex around the wifi transmission request so that wifi tx can't occur without first obtaining the mutex. Conversely is there a way to register a callback for before and after a wifi transmission, such that a mutex could be place around the other power consuming event(s)?

Thank you

No, we do not have that. I'm not even sure if that's possible as some of the transmission logic (e.g. retransmissions when no ack is received) may be done in hardware.
