MODEM - Usb problem & couldn't query SIM slots: QMI protocol

[fxc]

Hi all,

When my pinephone wake up after sleeping period, i have noticed this problems.

-network manager in app parameters disappear.
-network icon not present on left top side

After Few seconds of wake up, all reappear and my SIM is locked.

This logs can be the cause, particulary "06:30:48" line "couldn't query SIM slots: QMI protocol error (94): 'NotSupported'".

Code:

How fix this problem ?




Second thing, today we have talking about me on IRC channel about usb issue problem with modem.

Seems to be the same problem which can be resolved with flash the FOSS firmware modem ! This can be the solution ?

But i don't know the URL of this FOSS firmware modem.

Thanks a lot for advices

Is this the modem firmware you are looking for?  https://wiki.pine64.org/wiki/PinePhone#Firmware_update

Actually they are looking for https://github.com/the-modem-distro/pinephone_modem_sdk. The link you mentioned explains how to update the stock firmware. The wiki needs to be updated.
