I recently got my device into a REALLY weird state where it basically became unusable. I tried SO many solutions through out the forum but I finally discovered the “doctor” command and that fixed everything.
Here’s what I did:
- Put the device into listening mode (hold MODE until blue light flashes)
- Run “particle identify” to get the device’s ID
- Put the device into DFU mode (hold down both MODE and RESET and then release RESET and wait for yellow light)
- Run “particle keys doctor your_device_id_here”
After I ran those steps my device re-connected and became visible on the Android app and in the build app. I just wanted to share this in case anyone else gets their Photon into a funk and can’t get it working.
