Actually, I am using the RUT955 running PPP, _not_ qmi.
For the requirement (or precaution) of a reset of the modem, using the GPIO for
the RUT955
looks like the proper solution to go.
In the opposite, ZBT confirmed, that on their WE826 there is no wiring
to (power-)reset the installed Quectel EC25.
@Daniel:
Could you please publish a complete shell-script on the openwrt forum, using
the GPIO on the RUT955
to reset the EC25 ?
Cheers,
Reiner Karlsberg

As similar problem can be observed when looking at swconfig. some switches
need a reset, others do not. for this purpose an "option reset 0/1" was
introduced in uci. In this case maybe "modem_reset" might be a good option.
This particular device (Teltonika RUT955) got a dedicated reset line for
the USB-connected internal Quectel EC-25 modem available as GPIO which
could be toggled on boot if needed (in user-space or by wiring up
device-tree magic doing that).
That's more reliable than using QMI to trigger the reset, and also more
generic in terms of people not even using 'uqmi' on that device.
Cheers
