I have read a number of forum posts about creating a second software serial port etc. but I do not understand this and I m looking for any guidance.
The MKR 1010 board have a UART on pin 14 (TX, output) and pin 13 (RX, input). In software, access it using Serial1 such as Serial1.begin(9600) and Serial1.read(). You do not have to disconnect the NFC reader because a different port used for programming and uploading. This only applies if you have not converted the board to use I2C.
