Hi all, new AirGradient user here. I purchased several of the AirGradient ONE’s with the built in SIM card (cellular network) for a new research study. I am in the UK in a well connected area however when I plug the devices into a power source, the devices turn on, powers up, and tries to connect, but cannot connect to a network and gets stuck on the screen saying ‘Initialising network connectivity’. Eventually the device gives up, reboots, and starts the process all over again.
Here is a summary of the information I received from the debugging log:
AirGradient Cellular Log Summary
-
APN Configuration Set: The device successfully executes
AT+CGDCONT=1, "IP", "iot.1nce.net"and receives anOK. -
Operator Scan and Manual Configuration Attempt: The module scans and finds available operators, then attempts to manually configure/register using
AT+COPS=1,2,"<operator_id>",7for the listed operator IDs (52004,52005, and52003). -
Timeout and Error: For each manual operator selection attempt, the module encounters a timeout waiting to apply the setting, followed by an
ATcommand failure yielding+CME ERROR: phone failure. -
Final Logged Warning: After attempting the manual configuration across the operators, the log records:
[A7672XX] Warning: Network registration failed! Final state: 5 (fail count: 0 of 3)and[AgCellClient] Error: Cellular client failed, module cannot register to network.
The log shows that the device times out and errors out (+CME ERROR: phone failure) specifically during the manual operator attachment phase (AT+COPS=1,...), preventing network registration.
Any help hugely appreciated, as we need to head into the field soon!
