Modem stopped working?

Hello!

I've been using OVMS successfully for about a month now. Everything used to work great, but now somehow my modem does not connect to the internet anymore. I've checked the SIM in another device and it is working normally.

This is the output from the log. Any ideas?

This keeps repeating...

Thank you very much!

Hmm, looks like this was some

Hmm, looks like this was some connection issue with the antenna. I've unplugged the modem board and checked the antenna connections, reassembled everything and it started right away again...

never mind :)

Same issue again

Looks like my GSM signal Quality has significantly degraded since the device was new. Already tried a different antenna and checked the internal connections. But I can barely get any connections.

Any suggestions?

Try swapping the internal GPS

Try swapping the internal GPS / GSM antenna cables (so swap them on the modem board, and then swap the external antennas as well). That will tell you if there is some issue with the internal cables or their connections.

I've already tried this. It did not help. Also checked all connections with a multimeter and they seem OK.

I guess something is wrong with the modem board...

Any suggestions?

Otherwise I will try to get a refund. It is not working for me anymore.

I have the same problem

I'd like to add that I have this same problem on my v3 module with the same software version (3.2.015). The modem worked for some months, and has randomly just stopped working.

my shell shows a continuous repeat of:

I (1241132) simcom: State timeout, transition to 2

I (1241132) simcom: State: Enter PoweringOn state

I (1241132) simcom: Power Cycle

I also note in the Status page I get this repeating:

[21:21:46]egpio.output.0.high
[21:21:46]egpio.output.0.low

Do you use hologram? About

Do you use hologram? About May my modem stopped working. I fiddled with it a bunch then finally put in a support call with hologram. They did a "SIM refresh" and it started working again.

modem suddenly stopped

If I use the microusb connector the modem starts working so it must be a power issue and not simcard related.

Allready did a full reset bu that does noet fix the problem.
