Electron no longer connecting after setup

Troubleshooting
1

I have setup an Electron today, it connected and all was good. I then flashed it OTA with a program that I am currently using on an existing Electron, with no changes. It never reconnected to the cloud. I have tried then flashing it again from the CLI, I have tried safe mode, I have tried flashing it via the CLI with Tinker and update and then flash again. Nothing seems to work. I have also deactivated the sim and reactivated it.

I also tried particle keys doctor followed by particle keys server, this has not worked either. Lastly I flashed it with a Tinker Debug program and have the following log:

I have also now tried another sim that I know works, yet it still won’t connect.

3

Have you got a charged LiPo connected?

What version CLI are you using?
What system version have you currently got on the Electron?

Particle or 3rd party SIM?

4

Fully charged LiPo

I have freshly installed cli. Strangely the device doctor didn’t run on my PC. It just displayed Name: Particle Device Doctor and returned me to the command prompt, so I installed it on my PC which allowed me to run the doctor, still no love though.

Not sure what system ver. my electron is, how do I check that?

Particle sim. I tried a 3rd party without realising I needed to flash with custom apn. I tried doing that but the setup keeps telling me the ICCID of the 3rd party sim is invalid so I gave up on that.

Put your device in Listening Mode (blinking blue) by - after powering up - holding SETUP/MODE for 3+ seconds then

particle identify

To get the version of CLI run

particle --version

It should be 1.27.0

If particle doctor doesn't work try (in DFU Mode)

particle keys server
particle keys doctor <deviceIDYouGotFromIdentify>
6

My system version is 0.6.4 and CLI is 1.27.0.

Particle Doctor worked on my laptop which I ran last week and it didn’t solve the issue.

7

Then it might not have worked as expected - have you tried my suggestion?
