It started with this particular Photon, where it was working just fine. Then one time after Flashing it via the Web IDE, it almost connected and then started flashing blue. After this, no matter what I did, it would go into listen mode on boot. So I then set up the Wi-Fi SSID and credentials etc. u…

Try this particle keys doctor <yourDeviceID> particle keys server

Ok, for some reason, even though openssl is in the system path, it can’t find it. So generated the .pem file manually. Now I’m not sure where the next step expects to find this file, but I did it nonetheless. I then did the particle keys server I got this in the output Found DFU device 2b04:d006…

Ok, my issues with the openssl path was that I didn't use a new command windows after adding openssl to my system path. So I did that and then did the particle keys doctor This time it worked! The device booted a few times and it seem like my code is executing (I see a breathing white LED), sin…

Yep, my Photon is working! @ScruffR , thank you. However, all this begs the question…what happen? Why did I have to re-generate the keys in the first place? What if this happens when these devices are in the field?

I updated the particle CLI using npm update -g particle-cli Didn’t look like I needed it, but, yes, it was worth it to ensure the CLI is up to date.

That will update the system firmware on the device, not the user firmware. Having the latest system firmware should do nothing but good, and you can always revert back it it doesn’t :smile:

A CLI update is required when new system firmware gets released in order to have particle update do the right thing. If you remove your current CLI installation and reinstall it via the new CLI installer for Windows, you should get auto-updates whenever a newer version arrives.

Yes, I thought you were saying “update the CLI”. Yes my photon already has the latest system firmware.

Also, making sure your CLI is up-to-date and doing “particle update” while in DFU mode never hurts
