I am trying to use the Adafruit HUZZAH32 - ESP32 Feather V1 to communicate with the M6E-Nano RFID reader. The provided SparkFun library for setting up this reader allows it to work with software serial ports however, I am struggling to get it to work with a hardware serial port since the Feather only has those ports. It has 3 serial ports which occupy the external variable names Serial, Serial1, and Serial2 from the HardwareSerial library but I am unable to set any up with the RFID reader. This RFID reader uses the SparkFun_UHF_RFID_Reader library but according to the Arduino IDE it is failing when calling the begin function from the SparkFun reader library. I am just wondering if anyone has been able to set up an RFID reader using this library using a hardware serial port as opposed to a software serial port. Just for reference, I am using and modifying the Example1_Constant_Read script that comes with the library which can be seen from the M6E-Nano hookup guide found on this link: [M6E-Nano Hookup Guide][/https://learn.sparkfun.com/tutorials/si … 1612634570]
Look at https://github.com/paulvha/ThingMagic/t … ib_special. I have made a number of changes and extra examples to the original library. Also those for ESP32 and hardware serial.
