Hello,
I use st25r3916 driver and DemoCycle from X-Cube-NFC6 app but devCnt for discovery is never more than 1 even though I have 2 tags next to the antenna and devLimit is set to 3.
Also I see state machine never goes to RFAL_NFC_STATE_POLL_SELECT
How can I further debug it?
Thanks,
Mihai

Hi Mihai,
what are the two tags you are using? If NFC-A then chances are that one is stronger than the other and the weaker one is not recognized as a collision during AntiCollision. You could work-around this by using rfalNfcaPollerSleepFullCollisionResolution() instead of rfalNfcaPollerFullCollisionResolution().
