On this very first cellular connection the module may take some considerable time to find LTE-M
network service; many minutes, up to 15 minutes. This is because the device does not yet know
the radio environment and must search all of the global LTE-M RF bands on each visible cellular
network. Connections should be quicker on subsequent attempts as the module will remember
how it gained service previously.
⚠
If you get an error response that is different than the one shown above (e.g., just
ERR14 UNABLE
TO CONNECT
), then the cellular connection has not been successful, and you should try again.
for troubleshooting advice.
With these steps completed, the cellular module has in fact successfully connected to the cellular
network for the first time and registered with the necessary u-blox servers to create the certificates
