I have a Boron running 1.5.2 that has been working flawlessly until the AT&T scheduled maintenance that recently occured. The device last connected successfully to Particle cloud on 9/1 at 4:10am. I have removed power from the device and tried resetting it. I also verified that my SIM card quota has not been reached. The device just produces a flashing green LED and never connects now. It is programmed to use SEMI-AUTOMATIC and NO threading. The connect code is below. Any ideas as to what may of happened during the scheduled maintenance?
The log does produce the following error now:
0000057764 [hal] ERROR: No response from NCP
0000111014 [hal] ERROR: No response from NCP
0000164264 [hal] ERROR: No response from NCP
Log.info("Connecting to Particle Cloud...");
Particle.connect(); //initiate connection to Particle cloud
if (waitFor(Particle.connected, 2 * 60000)) {
Log.info("Connected!");
return 1;
} else {
Log.error("Unable to connect to Particle Cloud!");
return 0;
}
If you consistently get “No response from NCP” you may have had a device failure, which was coincidentally at the same time as the maintenance, but not really related. You should contact support as you may be experiencing a known issue with the SARA-R410M-02-B in Boron LTE devices produced before October 2019.
Getting a cloud debug log may be helpful in diagnosing the issue.
Hey @rickkas7
I will contact support. I did run the Cloud debug and here is the output:

Yes, that looks like a failure of the cellular modem.
Support confirmed it was the modem issue as described in technical advisory (https://support.particle.io/hc/en-us/articles/360052556854). They are replacing it. Thanks for the help!
