PPPoS compoment is having rapid disconnection with GSM over 4g network type

Postby rajkumar patel » Tue Aug 14, 2018 6:45 am

hello,

in one of our product development we are facing the issue like pppos connection disconnection while providing network connectivity to the ESP32 ,over modem(BM817C-E1 -- a broadmobi modem) with 4g network, within few minutes(2-5 min).
however, we are able to establish the ppp connection again as per our state machine.

FYI, this is not the case i am seeing with the 3g network.

so my question,
does the pppos interface's effectiveness or fidelity has anything to do with the network type(2g/3g/4g)?

so far i have not found any thing on this issue. that's why counting on more upon your response.

thanks. :)
Regards,
Rajkumar M. Patel

Hi Loboris,

We have taken below example for our reference purpose regarding PPP component porting and facing some issues while testing with GSM Module which is mentioned above.

I've used PPPoS only with Simcom 2G/3G modules and had no disconnect issues.

You can try enabling debugging to get all the PPPoS debuging messages, maybe it could help to detect the disconnect reason.

Hi Loboris,

Yes. We have put few debug prints into PPPoS Component but didn't find much details from that. Still we will put few more debug logs to get exact reason for disconnection issue.

Actually, We have tried with Broadmobi modules with 3G and 4G connection.

Have you enabled → Component config → LWIP → Enable PPP support → Enable PPP debug log output ?
If enabled it prints detailed log of PPPoS communication.

Yes, We have enabled that option as well and we were getting Task Watchdog with that enabled prints.

So, I need to check it like why it is causing after enabling debug prints and will let you know results after that
