Adding “Particle Keys Server” was the solution! Thanks very much!
Here’s the total solution that worked for me:
- Install Particle CLI on my computer (command line interface) link
- Connect the Photon to my computer via USB
- Open a “command prompt” window on my windows computer. (type “command prompt” into the start menu search box)
- Navigate to the directory C:\OpenSSL-Win32\bin> (by typing “cd C:\OpenSSL-Win32\bin”)
- Place the Photon device in Listening mode (blinking blue) (by pressing the setup button for 3 seconds)
- Enter “particle serial identify” into the command prompt window (to get the device ID)
- Place the device in DFU mode (blinking yellow)
(Hold down BOTH buttons; Release only the RESET button, while holding down the SETUP button;
Wait for the LED to start flashing yellow (it will flash magenta first);Release the SETUP button) - Enter “particle keys doctor <DEVICE_ID>”. (replace <DEVICE_ID> with the ID from step 6.)
- Enter “particle keys server” into the command prompt window.
- hit the Reset button and the Photon should connect properly
That fixed it for me. Thanks for saving my Photon!
