ERROR: Failed to power off modem

Hello together,
i have a boron which does not connect to the internet. I flashed https://github.com/rickkas7/boron-clouddebug/blob/master/boron-clouddebug-v1.3.1-rc.1.bin

to inspect whats going on. I get following log.

Does this device suffer from an hardware fault, if the modem cannot be turned off?

Kind regards!

Hi @user1235 - this corresponds with a known modem issue. Would you mind opening up a support ticket? I’ll get you sorted!

Hi there,
tried https://github.com/rickkas7/boron-clouddebug/blob/master/boron-clouddebug-v0.9.0.bin and with this the boron connects to the cloud.

Hard power cycle helped.

Are there different hardware revisions regarding the modem?
Is there a recommended device OS version to avoid this issue?
Can we upgrade from 0.9.0 to e.g. 1.4.2 regarding this context?

Hi there,

Great! I suspect the issue was with a problematic OS/bootloader state on the device, remedied by flash of the monolithic cloud debug firmware.

You should absolutely upgrade to 1.4.2. While it’s easiest to do this OTA, I find that doing this from Particle CLI running particle update and particle flash --usb tinker is the safest way to do so on a device recovering from a fragile state.

@marekparticle Are you able to elaborate just what this error means? I have seen it before when I am using Manual mode and there for there should be no reason for the Particle OS to attempt to “Power off the modem”.??

Hi @ric_hard - the above is a serious instance of modem failure. Are you seeing ERROR: Failed to power off modem exactly?

Would you mind sending the complete logs/context in which you’ve seen this error in your support ticket? Are you using threading in your AT commands only application at all?
