OK here’s some interesting input… I went through this troubleshooting:
And I’m able to turn on the cellular, connect to a network, get a RSSI value, and everything EXCEPT connecting to the Particle Cloud.
Wondering if this is just lousy network and it can’t make the connection to the cloud.
Log of the serial interaction…
Running in SEMI_AUTOMATIC mode, cellular modem is OFF at boot,
not connected to the cellular network or cloud.
System RGB LED will typically stay White, until connecting to cloud.
Connect a serial to USB adapter on the TX pin to see debugging output.
