Multiple tags are not detected

[Mihaita Ivascu]

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().
