My Argon breathes cyan but cannot be reached. The web ide shows that it’s connected and even lets me “flash” the Argon and says it’s successful, but the Argon is not actually being flashed. It just keeps breathing cyan and doesn’t load any firmware. I’ve tried signaling it, but that doesn’t work eit…

You’ll need to install the CLI tool . It’s really powerful and does a lot more than just allow you to flash code either OTA or via USB. Once 0.9.0 is out, you’ll want to do this: download the 0.9.0 system, Tinker, and bootloader .bin files for the Argon from the repo put the Argon into DFU mode …

I’ve lost track… Have you tried particle keys doctor <DeviceID> and particle keys server? The red flash might indicate a key issue, although I wouldn’t expect it to come online with bad keys.

Is there a list of ports and/or ip addresses that must be allowed to communicate?

I want to confirm that you’re still seeing the occasional red flash, correct?

Thanks. I replied in the associated support ticket.

I have a very similar challenge. And I get the single red flash as well. Any solution, or is it still being investigated?

Are you running Device OS 0.9.0? Did you try the Have you tried particle keys doctor <DeviceID> and particle keys server? Also, if you put the Argon into Safe mode , does it start to behave (e.g. be pingable/signal-able)?

Device OS 0.90, yes. I’ve done the Particle keys repair numerous times. It’s not constant. And many times, rebooting the Argon will allow the Xenon to connect properly. I’m really getting tired of trying to make my Particles just work. I’m not throwing in the towel, but it would be so nice if w…
