Hi Particles,
I have a B523 SoM Particle module running on a M.2 SoM Evaluation Board, which I last used in 2022 and now can’t get to connect to the mobile data (cell) network. I’m using a 12 volt 2A power adapter as the supply and it appears power is getting to all the right places. The system LED flashes green to infinity and there is no accelerated flashing or any indication it is trying to connect to the network. I used CLI to update the module to the latest version and returned the following confirmation:
PS C:\Users\XXXX\Desktop> particle update
Updating b5som e00fceXXXXXXXXXXXX to latest Device OS version
[█████████████████████████] 100% | Flash success!
Update success!
I also reactivated the SIM, giving it 24 hours to stick with the Telco as I am in Australia but the green flash continues. The Particle console IDE depicts no change in the OS version. The console (predictably) lists the unit as offline.
This unit worked fine in 2022 and I have not changed the switch / jumper configuration on the eval’ board (please see the image for setup).
Before going to Particle support, has anyone any idea why this unit wont connect. I have several Electrons working at this location and my phone is fine, so the network coverage should be good. Does anyone have any ideas why this may not be working?
