Upon trying to establish a 3G connection with the GL-MiFi + Quectel UC20 daughter board I am stuck in the final PPP negotiation phase.
I have found I have to use /dev/ttyUSB3 for the data and not /dev/ttyUSB2 as with the ttyUSB2 port the dial script will give an ERROR at the ATDT command where the connect is being initiated. When I change to ttyUSB3 the connect script succeeds.
The CHAP authentication succeeds as well in the subsequent PPP negotiation phase, but after that I run into problems that I haven’t been able to solve with a couple of days of googling.
Here is my log:
