We have several FX30s modems installed on sensors. To save battery, the software disconnects the mobile broadband connection in case there’s no more data to send. The problem we have is, that on several sensors, the FX30s cannot find the SIM Card anymore (LE_SIM_ABSENT) as soon as a reconnect is required. Sometimes the SIM is found again after a reboot. The issue does not appear on all sensors and we were not able to reproduce the issue inside our office. Therefore it might be a mechanical problem because of the outdoor temperatures or humidity.
Did anybody have similar issues and knows how to solve them?
Some googleing brought me to this thread: SIM card can not be detected.
Does the FX30s also have such a SIM holder? Unfortunately the AT+WSHS command is not available on the FX30s.
FX30 Version: R13.1.3.001
Thanks in advance
