I have HC-12 RF module which is receiving data from my PC. I want to connect that with the AXON board and read that data.
I connected that module at given RX/TX pins on pin2 and pin4 labeled as uart2. but I am not getting any messages.
If I read those messages using FTDI on my computer or AXON board, then it is showing messages, means that HC-12 is working fine.
Can anyone guide how to enable other uarts of AXON board given on gpio pins. Because I don’t want to use any FTDI modules, I want to connect my HC-12’s RX/TX directly to tx/rx pins of GPIO.
