Ok, found a FAQ for the RFID problem (Problem in der Verbindung zum RFID bei Verwendung des Nanos mit dem Aufdruck „2038“)
Switching pin 9 with 6 solve the issue!! Because I’m using this version of the firmware, is it correct to change as following?
- const uint8_t nfcResetPin = 9; —> const uint8_t nfcResetPin = 6;
- const uint8_t statusLedPin = 6; —> const uint8_t statusLedPin = 9;
And now also the powerbank issue is fixed!!
Thanks!
