Setup fails App and serial setup

While following the nicely written setup instructions, I’ve only come up against issues trying to set up the Photon. I’m not willing to download toolchains and go down the development road as this is supposed to be fairly high level. dfu commands gave errors that I didn’t understand and didn’t do anything.

Can anyone review the following results and advise what I might be missing? I’ve also tried multiple Win10 machines.

App Setup
No mobile devices are able to connect and set up the Photon. It tries multiple times and reports that it is unable to connect via wifi.

Serial Setup
I installed the driver and seem to be able to connect serially to the Photon, but still can’t complete the setup…

Your device id is 43001f0...........5

Making sure the LED is blinking blue, I proceed as…

! PROTIP: Hold the MODE/SETUP button on your device until it blinks blue!
! PROTIP: Please make sure you are connected to the internet.

> I have detected a Photon connected via USB.
? Would you like to continue with this one? Yes
! The Photon supports secure Wi-Fi setup. We'll try that first.

! PROTIP: Wireless setup of Photons works like a wizard!
! PROTIP: We will automagically change the Wi-Fi network to which your computer is connected.
! PROTIP: You will lose your connection to the internet periodically.

Setup Wifi via serial
I try a wifi setup via command line, serial and get a blinking green light. It never ends up connecting to anything…

C:\Users\Jeff>particle setup wifi
? Should I scan for nearby Wi-Fi networks? Yes
? Select the Wi-Fi network with which you wish to connect your device: UNITE-Cx
? Security Type WPA2
? Cipher Type AES
? Wi-Fi Password xxxxxxxxxxx
Done! Your device should now restart.


What kind of network are you using, 2.4GHz, 5GHz, enterprise, etc? That might have something to do with it. If you’re able to setup a hotspot with your phone, would you be willing to try that to eliminate possible networking issues?

I’m using my 2.4GHz hotspot, but I’ve also tried my home network 2.4/5. Both have the same result.

I bought another one and it works great…faulty photon?

If it was a faulty unit, you might want to open a support ticket at
