Problems with 4G Sim cards on BGS5 | Telit Cinterion IoT Developer Community

July 18, 2019 - 7:38pm, 3053 views

We experiment the following problems when interfacing BGS5 with a 4G SIM card:

the first GPRS connection (HTTP) performed after a refused Circuit Switched call is affected by a module reboot that happens randomly either before the connection or after the connection.

If no Circuit Switched calls are performed, all gprs connections correctly operate with no unwanted reboots.

No problems were present with 2G or 3G SIM cards, with the same hardware.

The firmware version is the latest: Revision 02.000, A-Revision 01.001.06
