P2P exchange + Powerdown timing problem

Discussion created by Romane Schelkens on May 5, 2018

Hello, I bougth two PN532. I implement P2P communication with DEP protocol in active mode. After communication, both PN532 receives the command "POWERDOWN 0x88 0x01"  (=Wake up on RF field & I2C and Generate an IRQ on wake up). Answer is correct and there is no error code. PROBLEM : when the target powers down before the initiator does, the "wake up on rf field" does not work anymore.What can I do?
