Have you follow everything in this guide?


You can also test your serial pins to see if they are working correctly

Try to connect GPIO14(TX, pin8) and GPIO15(RX,pin 10) together using a jumper cable.
Then if you run minicom it should echo what you type. if you break the connection between GPIO14 and GPIO15 it shouldn’t work.
