The GSM gateway module is online to GSM 2G telenetwork M2M. The LED lamp will blink red every second after connection to the telenetwork.
The APN will default be “internet.”
Then the module is listening to the 433,92Mzh band, and it will catch and save signals from the ThermIT sensors in the area within 20 to 30 meters in diameter. It saves any received data, but it also overwrites data received from the same Sensor_ID until it is transferred to the hosting server.
