Hello everyone! I am experiencing problems on connecting an electron to the cloud. To explain better, I had 2 electrons and both of them were offline since 1 year. I powered up the first one with the SIM card of the second (my error, I did not check numbers).
Immediately I have seen in the particle dashboard that the electron and the SIM card went online, but the strange thing was that I was not able to call functions on the electron from the particle cloud. So I decided to connect it via USB and use the CLI to “particle update” and flash a new user firmware, just changing the name of the particle functions. The firmware are only a couple of lines of code, no system mode changes or thread enabled,(just a loop with particle.publish every 5 seconds)
Doing so, the electron is no more able to connect to the cloud: it remains breathing white, and after about 25/30 seconds it goes to breathing blue. Then, after 30 seconds, it starts blinking blue. Then after 2/5 minutes, again breathing blue.
I tried doing so:
DFU mode
"particle update"
(firmwares updates, but still the problem)
“particle flash --usb tinker”
(loads firmware but problems remains)
Not able to call “particle identify”, because I cannot enter in safe mode as the electron is disconnected.
“particle device doctor”
(followed procedure, when done, electron is not able to connect).
“particle keys server”
"particle doctor " (electron ID got from cloud dashboard)
tried with changing sim with the other electron.
Nothing happens, the electron does not want to connect with the cloud…
Tried all these steps again with a personal very simple firmware or tinker but problem still here.
I also tried to push quickly the mode button to check how many signal blinks are available, but nothing happens as Electron is not breathing cyan but white…
Do anyone have a solution? I do not think it is a hardware problem, is there a way to check it?
