AW: ModemManager[178]: <warn> Reloading stats failed: Couldn't get packet statistics: QMI protocol error (15): 'OutOfCall'

[Ralf Glaser]

Hi,

would it hurt to enable the ID_MM_QMI_CONNECTION_STATUS_POLLING_ENABLE property?
These are mobile devices integrated in vehicles that belong to the cusomer of a customer which makes debugging rather painful 🙁. So i prefer to add some test even though they might not be necessary...

In case you are interested in a device with an i.MX7d and a Quectel EC21 for testing/development purposes please let me know.

Best regards,
Ralf

Hey,

Nice! Please try to gather as much info as possible during those
disconnections, and let us know if you can still experience the
OutOfCall errors.

> 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)?

The ID_MM_QMI_CONNECTION_STATUS_POLLING_ENABLE property should only be
enabled for modems that don't emit WDS indications. I think I've only
found a couple of devices that need that, all the others should rely
on the WDS indications normally. If your debugging shows that you're
not receiving and processing the WDS indications properly, you may
need to add it (as a udev tag, you cannot enable/disable in runtime).
