We discussed this with quectel. There is a problem within BG95. They will find the problem.

I write for those who have this problem.

We are facing the same problem here… We noticed that without the USB_DP and USB_DM connected to the PC, the TCP connection does not work…It does not make sense to us… Did Quectel find the problem?
