I do realise there is a number a topics on similar issues, I have worked through a lot of them, but have not been able to resolve my issue. Hope someone can help. Please see below:
The photon have been working just fine for about two months running the code in this project.
I have not made any changes to the code I simply switched the photon to a new PCB. These were all pre-assembled by PCBWay so I doubt that there is a problem on the new board. Regardless, and in fear of losing another Photon, I hooked up an old Arduino UNO to match the pin layout and it works like a charm.
The Photon was working, and then it wasn’t. Steps I have tried:
- I am unable to put the device in SAFE MODE
- I am unable to put the device in LISTEN MODE
I can however get the device in DFU mode, so I did the following via CLI:
- Particle Flash
- Particle Doctor.
Both completed (Doctor returns a timeout error during Wifi setup) but after restarting goes back to the RED flashing error as per the video.
My apologies if I a missing something trivial.
