I recently had my core go offline after it’s been online in a project for about two years. I reset it and now it just breaths cyan as soon as it turns on. I tried running ‘particle flash --usb tinker -v’ in DFU which seems to work, but it just goes back to the same thing again.
Are you sure it’s breathing cyan and not white - sometime it’s difficult to distinguish when you haven’t got the direct comparison.
You may also want to reflash the CC3000
particle flash --factory tinker -v particle flash --usb cc3000 -v particle flash --usb tinker -v
Actually looking at my running photon at my desk I think you are right. It is breathing white…
First command yields ‘I did not recognize that device name or ID, try opening https://api.particle.io/…’
This sounds a lot like my issue. Is it just dead?
That is possible - I’ve heard of others report similar things due to the CC3000 just dying.
