RAK2013 Minicom ttyAMA0 offline --

Issue: Hello all and @velev ,

I am using RAK7244C and the latest Firmware with Pi 4 Model B. while setup the LTE, in minicom once enter the “at” , nothing will appear and it show the offline as well.

please note that baud rate config corrected. I follow the same topic with this :

According to above topic same issue but i configure the corrected baud rate in minicom.
And interesting thing is according to instruction connect the RAK2013 with the RPi via USB for communication:
it work perfectly and can access the internet as well. But when I unplugged the USB cable it will not work.

Please note I follow the each instruction above topic I mentioned and still no luck.

appreciate any idea to overcome this issue?
