GSM/LTE modem troubleshooting

This test requires the RBRcervello to have an activated SIM-card installed in the GSM modem as described in Telemetry. If GSM is not going to be used in this deployment, this test can be omitted.

After finishing the previous test, wait for the "RBRcervello>" prompt to appear again. Type "diagnose gsm" and press enter. The GSM test will wait for any ongoing communication to finish and will diagnose the connection to the internet via the GSM modem.
