I’m at a loss as to what to do next. A Photon continuously blinks blue and I cannot get past this stage. This is what I have done so far and I welcome any further suggestions (even if it is to throw it in the bin as I’ve wasted so much time already):
Started by trying to setup wifi credentials using my android phone - phone could not disconnect from the photon once it had the wifi settings.
Updated the firmware (it was very old) using dfu-util and tried again. Same result.
Tried a different usb cable and computer and used particle cli to update firmware - update worked. Then tried particle setup and failed after receiving wifi settings (yes, the settings are correct). Still flashing blue.
At this stage I have exhausted all my knowledge. Just to double check I took a new photon out the packaging and it set up perfectly. I now have 11 working photons and 1 obstinate one. Any suggestions from the gurus before I bin it?
