I was running Photon application for about 1 year. On Apr 3rd Photon stopped working. FW version was 0.5.0 and I tried to set up WIFI again. It did not work. It is possible to get into WIFI, get IP and I am able to ping it, but instead of logging into cloud there is one short red blink on LED and the login procedure starts from the begining.
I have tried particle keys doctor on 0.5.0 and it worked fine. No change:-(
I have updated particle CLI on my PC and updated FW to 0.6.1:
system firmware version: 0.6.1
Nothing has changed. I am still not able to login to cloud. I have repeated particle keys doctor and it did not help. The photon is visible via serial:
D:\Particle>particle serial list
Found 1 device connected via serial:
COM6 - Photon
but not accessible (probably because of failed cloud login procedure)
D:\Particle>particle serial identify
! serial: Serial timed out
I can get version and info via putty when in config mode.
Any idea what could be the problem? How to further troubleshoot?
thx a lot
