Hi All!

This thread is awesome! Lots of questions here about blinking lights, I’ll try to provide the answers where I can:

- How to - electron safe mode

- Electron fast flashing red while fast flashing cyan, can’t count the blinks

- Electron factory reset?

- Electron is flashing solid blue (listening mode / setup mode)

- Electron is flashing green forever

- Electron is flashing cyan forever

(I’ll edit this in place as I add more)

Thanks!  
David

Well, timeouts can be catered for in new firmware.  
Switching to TCP would help determine (diagnose) basic carrier connectivity as its a more resilient protocol (at expense of bandwidth). I did notice however that switching protocol through the CLI seems more involved than a simple protocol change - it looks like maybe also addresses of particle servers need modifying?  
I also thought it maybe a UDP fragmentation issue during handshake, but the fact that I got a breathing Cyan a few times seems to rule that out.

I have an old (10yrs) 2G soap-bar phone nearly that runs over giffgaff and it reports 5 bars, i use that as my “signal tester”.

I “may” try the 3rd party sim switch in a few days if I dont get particle help.

I have the same problem. 2G in UK. After power on it flashed green for a while until it found a signal, then I get fast cyan flashing (approx 4 blinks a second). that goes on for 20-30 second and then the flashing gets faster (cyan again approx 8/second), then it flashes red for about 250ms then it goes back to flashing cyan (approx every 250ms).  
I did manage to get breathing cyan if I left it going for about an hour (which lasted long enough for it to register and I claimed it on my account), so the device does work, but I think it must be a problem with the UK carrier (O2?)

Any updates anyone?

@Padge,

sounds exactly like my scenario over here: [Electron G350 connectivity (flash sequence)](http://community.particle.io/t/electron-g350-connectivity-flash-sequence/20216)

I just get the feeling (in my scenario) its a composite problem of SIM connection (holder), carrier signal, and data provision. MVNO’s often get a worse deal if the tower is busy and at certain times of day - this makes testing a problematic issue for me, although my 2g phone is able to send TXT its so old it cannot do data :(. My proper phone is 3/4G so its not a good comparison for Electron G350.
