I am new to the Pi from the Arduino world.
I have a FONA 3G module that i previously had hooked up to an Arduino and is worked fine.
Now the FONA is hooked up to the Pi 3 just as instructed in the following tutorial. https://www.digikey.com/en/maker/projec ... c5c1dc2ff0
I followed the advice on this forum to add
Code: Select all
I cannot get any response from the serial monitor after sending a AT command. I am really confused now. I flashed a new image and started from the top but still no luck.
The FONA 3G works fine with the Arduino but I cannot get it to connect with TX RX on the Pi.
Thank you for your help.
