on_tx_comp()

Called when transmission is complete.

This function is called from within the MWX library with data stored in ev as packet_ev_tx when the wireless packet transmission is finished. If this function is not defined in the application, a weak function that does nothing is linked.

ev.u8CbId is the ID at the time of transmission and ev.bStatus is a flag indicating success (1) or failure (0) of the transmission.

Setting b_handled to true in this function tells the MWX library that the incoming packet has been processed in the application. If set to processed, it suppresses unnecessary processing. (Do not call event callback functions for the_twelite.app, .board, or .settings)
