Help for photon blinking white


#1

My photon is blinking white every time I restart it, I think that is in semi automatic mode but I need to bring it back to automatic mode and I don’t know how to do it


#2

Flash some code that doesn’t engage SEMI_AUTOMATIC

To flash OTA you should use Safe Mode to get the device online and then flash.

I am using a BORON and the same thing has happened to me. But I can’t connect to it over LTE, and the DFU does not seem to work. Tried factory reset and that failed also. Any help would be appreciated.


#4

Have you tried

And in what way is that?

this is not a very enlightening symptom description.

Thx. Figured out how to get it into safe mode. Problem stemmed from using “SEMI-AUTOMATIC” mode incorrectly.

DFU issue is unrelated. I keep getting “No DFU capable USB device available” error when trying to program the device from visual studio Particle plugin. Ran the installer and tried uninstalling / reinstalling, but so far no luck. The statement DFU not working was to simply indicate that I can’t just reprogram it over USB.

Are you on Windows?
If so, try zadig to install the drivers.

How did you get it into safe mode. When i follow the procedure outlined, i was able to get my led to blink with the mangeta color while still holding the mode button. On releasing the mode button, the led reverted back to a white blink. Any help will be greatly appreciated.

The device needs to be running before you press/hold SETUP/MODE
