I’ve been having repeated issues with multiple Photons, especially when trying to change the wifi network.
In this current iteration, I recently moved so I wanted to reset a Photon in a project, add the new wifi network, and then flash the current code.
This afternoon it was relatively straightforward to “reclaim” the device (as a side note, wouldn’t it be great if the iPhone app could accommodate changes in the wifi without going through the ownership process?), but when I turned it back on this evening, the device wouldn’t connect to the wifi. I was able to “reclaim” the device a number of times, but never did it reconnect to the Particle Cloud.
particle flash --factory tinker seemed to have worked, but the next suggested command (for the cc3000 chip) did not:
particle flash --usb cc3000 running dfu-util -l Found DFU device 2b04:d006 Error writing firmware...file does not exist and no known app found.
At this point, the status light seems to always flash yellow. The device seems to be stuck in DFU mode, but it isn’t available through the terminal:
particle serial identify ! serial: No devices available via serial
Any suggestions? Thank you.
