We have a Banana Pi-D1, with Lamobo-D1 OS. We also use an EC25 with 4G Simcard.
When we try to connect to the EC25 on BananaPi-D1, using AT command, we get a time-out error. Actually, the PPP module does not receive any response from the EC25, thereby time-out error occurs. It is the same case if we use Quectel-CM.
We can successfully get an OK response on Windows and Linux, but not on BananaPi-D1. Please help us with resolving this issue.
