On Page 16 of the data sheet, there is the following diagram of start-up flow:
Specifically there is the first bubble I find interesting which states "TX Powered without RX Active." However, according to WPC spec and contrary to my interpretation of this flow diagram, there is nothing the RX can do to evade the TX from extending a ping... What I'm investigating is the case when RX battery has already been completely charged and issued an EPT Charge Complete packet to TX, and then left for some time on the charger while the battery is depleted. Is it possible that:
(A) The TX does extend additional pings, which RX cannot stop it from doing, but the RX continue sending an EPT response to the ping until the next cycle of removing RX from TX, and re-placing RX onto TX
and/or
(B) The TX is controlling this, and does not extend additional pings to the RX until it's detected the next cycle of removing RX from TX, and re-placing RX onto TX
Kind thanks,
Billy
