BGS2T ignore DTR signal | Telit Cinterion IoT Developer Community

February 7, 2023 - 6:14pm, 476 views

We have just bought 3 pieces of Thales BGS2T. We have a problem with these modems. We make CSD calls to other modems. If We call to other modem and Software Stop the call (DTR Signal go to off) BGS2T remain the call during other 50 seconds. We have more BGS2T and only these 3 BGS2T have this problem.

We have compared some BGS2T with AT&V and AT commands are similar.

I think the modem ignored the DTR signal and stop the call after some timeout, but this is a problem for us. Can You help us?.
