PN532 error 0x0B - RF protocol error

gustaf — Mon, 15 Feb 2021 15:41:06 GMT

Hi,

Is there any good explanation for the error code "0x0b"? One of our PN532's, while communicating with a Mifare FOB, is returning 0x0b and 0x06. The communication looks to be working fine for a couple of communications but after a couple of seconds, we see a bunch of these errors.

I should mention that we are toggling the RF field on and off every 50 ms unless there is a communication ongoing.

Hello @gustaf ,

I am not sure how you test , did the card stay on the antenna whenever RF is on/off? maybe there is some noise during the RF on, you may try to delay the polling a little bit longer after RF on.

Hope that helps,

Have a great day,
Kan
