Nice! Please try to gather as much info as possible during those<br>
disconnections, and let us know if you can still experience the<br>
OutOfCall errors.<br>
<br>
> I also found the ID_MM_QMI_CONNECTION_STATUS_POLLING_ENABLE property. Would you recommend enabling it (aka are there interesting side-effects to expect)? If yes, is it possible to enable/disable this feature during runtime or shall i patch 77-mm-quectel-port-types.rules
(we are using Quectel EC21)?<br>
><br>
<br>
The ID_MM_QMI_CONNECTION_STATUS_POLLING_ENABLE property should only be<br>
enabled for modems that don't emit WDS indications. I think I've only<br>
found a couple of devices that need that, all the others should rely<br>
on the WDS indications normally. If your debugging shows that you're<br>
not receiving and processing the WDS indications properly, you may<br>
need to add it (as a udev tag, you cannot enable/disable in runtime).<br>
