I fail to connect to booth of my just recieved new Photon modules. Blue LED is blinking, I select Photon -xxx soft AP and the Particle app shows message " Connecting to Photon …" for as long as I let it run. Same result with two different Android units. Where do I start looking?

@msens , are you using a 5GHz access point? The Photon will only connect to 2.4GHz APs. Also make sure that if you have a multi-band AP, you have different SSID names for the 2.4GHz and 5GHz bands. Finally, depending on your location, the Photon can only connect to channels 11 and lower. :smile:

I supplied SSID credentials via Putty and got the fixed blue light but no automatic reset. After manual reset the blinking green but still no connection. Network is 2.4 ghz, channel 3 and at -54dBm. (My IMP module connections are all ok…) Is there any way to ask Photon to show stored SSID creden…

show stored SSID credentials --> guess not for now. Fixed blue is weird… did the Photon respond to the SSID input?

I try again: Clear SSID data by pressing SETUP until fast blue. Enter SSID credentials - Photon replies"Thanks , wait …" After a few seconds off LED is back fixed blue. 4 . Manual reset and blinking green. an then suddenly the module connects , updates and goes into cyan breath and I can …

Ok so one Photon is working. What’s wrong with the other?

Yes, I really like to know that. I tried the same process with module 2 several times but it stayed green blink. Module 1 now connects at every reset. As for now I consider initial setup process too unreliable , hopefully you can provide some expanded debug possibilities later on. E.g. command…

@msens i can help you get it running if you are keen. Ping me on this thread anytime :wink:

Thanks, although I finally managed it myself. After a firmware reset the Module 2 also connected by itself and booth Photons are now visible in the Cloud.
