Green LED never stops blinking after antenna was reconnected to Electron

Dear all

After reconnecting antenna to Electron it never stops blinking green. I have not found any tips for this case. My OS 0.8.0-rc.14. Before reconnecting antenna it used to work fine. No reflashing has been done yet. regards

Dmitry

Did you, by any chance, remove/reattach the antenna while the device was running?

First, just to bring everything to a clean slate, can you run

particle update
and
particle flash --usb tinker

in CLI, with the device in DFU Mode and connected via USB?

From there, would you mind downloading and installing Electron Cloud Debug (link) on the device? Upon doing so, please send me about ~10 minutes or so of logs produced by the device while it’s having trouble connecting with the Cloud. It’s worth blocking out the Device ID and ICCID of this device as reported in Cloud Debug (but please PM me those details).

The best way to produce these logs is with particle serial monitor --follow in CLI.

Please note both installation and de-installation instructions contained within the above Cloud Debug link!

Detaching/reattaching antenna is harmful?
Actually I used to do it with my test to simulate a no-signal case (for example in the Underground)

Hi and thanks for the tips. Done as suggested (see below). I will send you my Device ID and ICCID via PM now. Looking forward to your suggestings how to fix it

Below is a long log produced when
particle serial monitor --follow

I also successfully did
particle device doctor
and restarted the device. It goes shortly to breathing white, then blue and starts always blinking GREEN non stop

Hi @animal-navigation - this device is really struggling.

At first, it desperately struggles to find a tower,

450.103 AT send      10 "AT+CREG?\r\n"
465.210 AT read  +   14 "\r\n+CREG: 2,0\r\n"

465.244 AT read  +   15 "\r\n+CGREG: 2,0\r\n"

and upon doing so after some time, it is rejected.

632.679 AT read  +   14 "\r\n+CREG: 2,3\r\n"

632.718 AT read  +   15 "\r\n+CGREG: 2,3\r\n"

The device’s SIM appears ok.

Towers often reject devices with very poor signal just because the registration process hangs. Can you run the Carrier scan application in Cloud Debug?

@Gorgo - we do not recommend de-/reattaching antennas to running Electrons because the transmitter in the modem is not intended to be operated with no load. This won’t necessarily force an issue, but is regardless not a recommended practice.

Hi @marekparticle

Thanks for the tip.s The cellular signal is not great at my office (maybe 3 of 5 bars) but it is not zero and I tried a new device which can connect but the ones I unplugged and re-attached antennas as they were active cant find mobile towers even with the same antenna.

By running the Carrier scan application do you mean this


Could you elaborate on

"Reset the Electron and immediately open the particle serial monitor.

The Electron will breathe white. Tap the MODE button once and a carrier scan will begin. You must do this within the first 10 seconds of startup otherwise the normal tests will be done. "

By Reset it means tap once and short the Reset button? Any more detailed guidance?

Maybe it’s also worth approaching any cellular tower to be able to have strong signal in the antenna to recover from ever green LED blinking?

@marekparticle
I have also done

particle device doctor

and it went successfully but did not solve the issue. Is there any other full factory reset procedure to start over and solve the issue by full reset?

  • Reset means hit the Reset button or un/re-power the device.
  • Yes, it’s worth to be sure that you have strong signal before proceeding. A Carrier Scan is a good way of evidencing suspicion of signal issues.

Again, the logs bear out a situation of weak signal (given the time spent looking for a tower and ultimate rejection therefrom), so it’s unlikely that a firmware change would do anything here. Cell phone service is not a reliable indicator of service available to Particle devices.

I always use:

particle update
and
particle flash --usb tinker
in CLI as a reset mechanism, but that’s not my best bet.

I’m really curious about these other devices - is it true that all devices whose antennas have been un/plugged while running have this issue? That strikes me as a potential culprit here.

One other comment about disconnecting/reconnecting the antenna – the U.FL connector is not designed to be disconnected/reconnected over and over – the total number of cycles is something like 30 (!). And you really need to exercise care each time. Sparkfun has some tips here: https://learn.sparkfun.com/tutorials/three-quick-tips-about-using-ufl/all

Oh that’s really good to know! I was quite repetitive and maybe brutal with the device which now has lower signal strength comparing to a fresher device with less reconnect cycles

Turned out that the trouble device started working when is in geographically closer to the o2 tower (the Particle cellular provider in the UK). It started being patchy in my office though. Another more fresh device (activated last week) is receiving signal in my office with the same antenna. My hypothesis for now is not that the single act of un- and re-plugging an antenna on a working device was NOT the cause of the any software glitch but it was rather the physical micro-damages of u.fl connector after multiple un- and re-plugging. The latter might have caused lower signal strength in the GPS module and the system started receiving cellular signal just under the threshold when the tower/device refuse to establish connection. This is my working hypothesis for now

The lessons from here are as follows:

  1. test devices in a physical proximity to a serving cell tower
  2. reduce the number of replugging u.fl antenna cycles and do it only when absolutely necessary
