Have been tasked to set a new APN in EEPROM via SMS while the current APN is wrong (3rd party SIM).
I can receive an SMS and store it’s APN to EEPROM when the device is online.
Particle.connect or cellular.connect seems to keep re-connecting (unsuccessfully) even in MANUAL mode. So I don’t see an option to get the Electron on the GSM network, accepting having a rejected APN and just wait there, for an SMS with a working APN?
Is there a trick to achieve this?
