B524 blinking green

Hi! I am having the same issue with my B524 SOM - how this story ended? My devices are blinking green without even trying to connect to the cloud. This is strange, cause just yesterday they were all fine. Could anyone help me please?

Blinking green means the device cannot connect to cellular.

Make sure the SIM is still activated in the console.

Removing all power to the device and letting it sit for 30 seconds before powering back up is usually a good idea as well.

If that does not work, use web device doctor to flash troubleshooting firmware to the device so you can get a debugging log.

SIMs are active. I removed power several times - still the same problem.
I have also tried web device doctor - there flashing to latest OS is always successful but there are no errors. What is strange:
I have found this line in console logs:
"NO CARRIER"
Which is weird, because:

  1. Device was connecting for a days form different locations (Poland) with no problem. I have been testing connecitons from 3 different locations now
  2. Last handshake was just yesterday, so there mus have been carrier... Is my issue related to cellular network providers or something?
    To be honest I am out of ideas for now:
  3. Device is communicating good via USB
  4. My Hardware seems to be just fine
  5. I have used 3 differens SOMs, 2 of them only on Particle M.2 DevBoard
    The only thing I have not tried yes is changing cellulcar Antenna - I mean, I have tested a few but all of them were from Particle - that is something I can do, but if everything were good before then would stronger antenna be needed...?

And also, I got this info in doctor:
It appears that you do not have a battery connected. A battery is recommended for all non-LTE cellular devices; running without a battery may cause connection or data transmission to fail.
It is true, but on my Hardware i am using 4V power supply with 3A so that should not be a problem. On devboard I have not battery but it it not needed. I think I have never noticed this info before - what might it be caused by?

Could you include more of the log? You may need to use particle serial monitor.

How are you powering the device? If it's falling back to 2G/3G it will need a battery; USB is not typically sufficient.

Here is my log:

On my hardware I have DC/DC converter for 4V. On devboard I am using externall 5V power supply connector.
However, I have experienced the USB power supply is sometimes not enought. But when I was not enough, deviced used to reset and retry to connect (LED was white for a second, and serial monitor was reseted). Now even if I try powering it only with USB it is not happening, It is constantly blinking green
There is also some mysterious log in console sometimes:

[net.ppp.ipcp] ERROR: Peer NAK'd an option unknown to us

What does it mean?

I don't know for sure why that is happening, however from the log we do know this:

0000003303 [ncp.at] TRACE: > AT+CREG?
0000003305 [ncp.at] TRACE: < +CREG: 2,5,"DF20","2C88647",2

The device was able to connect to a tower, which is why it's fast blinking green instead of slow blinking green. It was registered (2), roaming (5, normal), LAC and CellID, and it was registered 2G/3G (2, not LTE).

The device goes through the PPP LCP/IPCP configuration. Then this occurs:

0000024993 [ncp.at] TRACE: < +CGEV: NW DETACH

The cellular operator disconnected from their side. It's not clear why it decided to do this.

There is a small chance this could be a power or signal-strength related, but the connection looks pretty normal otherwise. It could be a problem with the SIM configuration. It could also be a temporary problem in the mobile network that you've connected to, which would also explain why it suddenly stopped working.

Thank you for your information!
I am trying to contact Orange - cellular network provider for Poland, maybe they would help. Also I will send one of SOMs to our team in Germany to see if connectivity in their country will be OK. This will help us determine whether is network issue or something else.
Is there anything from Particle side that could be done? Maybe you can change SIM or SIM settings? Or can you confirm that my SIMs are properly configured in your system?

Ok, in my opinion this is an issue I cannot handle myself. I have just confirmed, that the same device which was not connecting to the cloud in Poland has just connected successfully in Germany - it is online, I can talk to it with no problems at all. This makes clear all things from earlier - why B-SOM is not connecting to network even when Particle Doctor says everything is all right and why Particle was working fine for weeks and suddently stopped working for no reason.
Please help me now, I guess it will be neded to contact my local provider or change something in SIM settings, but my options are limited...

I'll have to have support take a look because I don't see anything obviously wrong.

It looks like the last traffic on that SIM was 2025-03-06 05:00:00. It looks like the SIM was deactivated and reactivated 2025-03-06 21:22:49. I presume you probably did this to see if that would get it unstuck.

I checked the traffic in Poland and there are many devices still online, and there doesn't seem to be a large number of devices to go offline around the time of your problem.

Thank you! So what is the next step I need to take?
The traffic on that SIM is correct, I have deactivated and activated SIM just to see if it would fix my problem, as you assumed.

Also, I have found this topic:

which is from Poland I guess and the time of problem seems the same as mine. However this topic is fixed, my is not yet - maybe some debug information from this topic will be helpful

Hi! Any info? I am stuck for more than 2 weeks now and I have no clue what to do next. Maybe Particle will change eSIM in my products?
I am 95% sure there is nothing I can do by myself now, all I can do is wait for your support. We were planning launching product on May this year but now it is strongly endangered...

This is being looked into by the cellular provider.
