Electron won't connect to cloud today- was working when I set it up yesterday

I setup my new electron yesterday- Everything setup fine and Tinker ran, and a small program I loaded posted data when it was supposed to. I unplugged it from LiPo/USB overnight. Upon restoring power this morning I get the following:

  1. Green flashing for 10-20 secs
  2. cyan flashing for 10+ secs
  3. one short cyan breathe cycle
    above 3 steps repeat indefinitely. The Electron no longer shows up in the PC console or mobile app.

I tried to get into safe mode- magenta is flashing when I release the mode switch, but it doesn’t stay flashing magenta- instead it breathes cyan for a second or so, then back to flashing green for a while, then it repeats.
Under these conditions, I can see the Electron as COM20 in Windows Device manager.
If I issue
"particle list"
CLI command, I get a response showing that BM1_Electron is online

If I put it in DFU mode, LED stays a flashing yellow. But, the Electron’s USB Com port does not show up in Device Manager under these conditions. Issuing a CLI command:
particle flash BM_Electron1 tinker (BM1_Electron is my device name)
I get the response:
Flash failed- timed out
which is what I would expect with no USB com port showing up in device manager (unless it programs via USB HID, for example- I don’t know)
I’m stumped- I can’t get into Safe mode, or re-flash it, so I don’t know what is wrong. Nothing at all was touched/changed overnight, after which time it went astray.
Any advice? Thanks

That’s kind of strange. I’d flash the Electron cloud debug software (in DFU mode, blinking yellow) which should show what’s actually happening via the USB serial debug.

If you want to flash it over USB, you should use

particle flash --usb tinker, otherwise it’ll try to OTA.

Thanks Moors7. With that command it reported that it flashed Tinker successfully.
But, it still exhibits the same symptoms. I will next try rickkas7’s suggestion re debug.

particle update might also help, depending on the current version of system firmware.

Thanks rickkas7.
I managed to flash the combined-electron.bin file and I am getting plenty of debug info via USB serial monitor. Most of it is not meaningful to me at this stage, but I do see a WARN: internet available, cloud not reachable (which is what I gather from the LED sequence).
and earlier on I see:
WARN Read00000508115 [system] WARN cloud socket connection failed -1
There are a whole pile of Modem AT commands sent- all that I can see are “OK” - successful.
Unless I stumbled upon it by mistake, I have NOT unclaimed the module.
Nothing in Billing would indicate anything wrong with the SIM account.
As I mentioned, everything was fine when I powered it down- then these symptoms as soon as I powered it back on this AM.

I’m not sure about trying this now when I just flashed the debug code from rickkas7 and am trying to follow up on the debug messages I get with him.

You can message me the whole log or submit it as a support ticket as I can’t tell what’s wrong without the whole log.

That is to be expected, since in DFU Mode the device is not a COM device but a DFU device and for that you need to have the correct DFU drivers installed.

Thanks ScruffR. I’m completely new to Particle and many of the other MCUS I work with do have serial bootloaders, so I was going on past experience. With help from others on the forum, I’m now able to flash code via USB and am trying to debug the problem.

The Particle devices can be flashed via serial or DFU.
To chose one over the other you need to put the device in the dedicated state.
For serial flashing you’d use Listening Mode and particle flash --serial firmware.bin
while for DFU you’d use … well … DFU Mode with particle flash --usb firmware.bin

Thanks again. I did read over the docs regarding the many operating modes. But, all of it didn’t sink in at the time, I guess. The Teensy and Expressif MCUs that I use basically have only 1 mode of flashing. I’ve only got about a day working on the proton and electron modules I just bought.


Rick- I responded to this by replying to the email I got from you, and attaching the file. Don’t know if this is the right way to go. I can try to attach it in a forum reply if you didn’t get it.
In the meantime I ran particle doctor. It did the first few steps OK, but not the keys. Here is the message it returned:

Resetting server and device keys

Put the device in DFU mode
Tap RESET/RST while holding MODE/SETUP until the device blinks yellow.
? Select Continue when ready Continue
Okay! New keys in place, your device will not restart.
The Doctor didn’t complete sucesfully. Make sure your device is in DFU mode (blinking yellow), and that your computer is online.: Error creating keys: Command failed: C:\WINDOWS\system32\cmd.exe /s /c “openssl ecparam -name prime256v1 -genkey -out 1b003a001347373333353132_ec_new.pem”
‘openssl’ is not recognized as an internal or external command,
operable program or batch file.

( I am running 64bit Windows 10)

That notwithstanding, when I rebooted Electron I did get back to a breathing cyan LED. I couldn’t however see it on the IOS particle app, nor could I successfully ping it from the PC console app.
So I thought I’d better re-flash Tinker, as I suspect that the debug file you asked me to load would have over-written it.
After tinker flashed successfully, I no longer get the breathing cyan- just a sustained flashing cyan LED.
I went back and did the device doctor procedure again- resulting again in breathing cyan LED but no connectivity to the cloud, according to the Ping.
I don’t know what to try next, but suspect the keys, I guess.

This indicates that OpenSSL isn’t properly set up.
If you use the Windows Installer it should get installed and added to the PATH environment variable - I guess that hadn’t happened before.

However, if you have a breathing cyan LED there is no keys issue.
How are you pinging the device?
Are you using console.particle.io?

@scruffr- My mistake. I thought it was breathing cyan, but I was looking at an angle. When I look straight down, I see it is actually breathing white. (Might have been some wishful thinking too). This was right after the particle Doctor routine. After I flashed the tinker program I get flashing green followed by flashing cyan. This never stops, although an odd red flash occurs.
I am pinging from console and there is no response.
There is an. openSSL - win32 folder off my C: root. It was created when I first started using the particle PHOTON a week ago. But, I am running Win 64 bit, if that matters. There are also lots of OpenSSL files in my Arduino folder under Expressif, as I use ESP8266, 32

Rick- here is the log. Sorry- I don’t know how to attach a file in this forum yet.

The important bit is whether or not OpenSSL is set up in your environment PATH.
If not, you need to add it.

If the device is breathing white, this indicates that the cellular modem isn’t even switched on - which might be indicating the running firmware is not switching it on.

Good news- I now have it working again, at least tinker anyway. There was already an entry
OPENSSL_CONF C:\openSSL-Win32\bin\openssl.cfg
in the environment variables- made by the particle install (dfu-util, I guess)
I added
Path c:\openSSL-win32\bin
After re-booting and running doctor again, it successfully restored the keys and I then went on to the last step re-installing tinker . Prior to this, I wasn’t getting past the keys successfully, and was flashing tinker manually using the particle flash --usb tinker command. I should note that prior to adding my the path, particle doctor was reporting it had changed the keys successfully, even though it went on to give the error message about openSSL not being found.
Now I am wondering:

  1. why did this happen in the first place
  2. how come the openssl_conf entry was made in the environment but not the other path variable that I had to do manually?
  3. the firmware running when this all started was "ds18B20_singleDrop, from Particle’s library examples. It ran successfully for a day or so on the Photon before I tried it on the Electron. The photon has been powered up and breathing cyan for the last few days, with this program, but I’ve not looked at its output. However, now I see that it is not working either. I won’t go into details but I had to “doctor” it and remove the windows com port driver for it (it showed a ? next to it in Device manager) , and let it get re-installed. After that I was back in business.
    I am just going to leave the Electron running Tinker for a few days before I try to put the DS18B20 firmware on it again.
    Thanks so much for your time/expertise.
