<div style="margin:0px;font-size:12pt">I recently updated by system to drop ppp/AT usage for CDC. <span style="margin:0px">Now my EG25 dongle work through qmi-wwan driver and libqmi.</span></div>
<div style="margin:0px;font-size:12pt"><span style="margin:0px"><br>
</span></div>
<div style="margin:0px;font-size:12pt"><span style="margin:0px">But I began to experience a major difference with the old protocol method. My signal quality<span> </span><span style="margin:0px;background-color:rgb(255, 255, 255);display:inline !important">is
not updated anymore </span>(the information output in Status chapter of mmcli -m any stays "cached").</span></div>
<div style="margin:0px;font-size:12pt"><br>
</div>
<div style="margin:0px;font-size:12pt">By the way, I use ModemManager 1.16.6 and libqmi 1.28.8</div>
<div style="margin:0px;font-size:12pt"><br>
</div>
<div style="margin:0px;font-size:12pt">From what I understand by reading the code, when using ppp/AT commands, ModemManager poll regularly the signal quality but with QMI , it registers to indicator events and wait for indicator (from libqmi ? from qmi-wwan
driver ? from the modem firmware ? I don't know yet)</div>

<div style="margin:0px;font-size:12pt">I see this worrying log in ModemManager debug log:</div>
<div style="margin:0px;font-size:12pt"><br>
</div>
<div style="margin:0px;font-size:12pt">ModemManager[1369]: <debug> [modem0] extended signal information reporting disabled (rate: 0 seconds)<br>

</div>
<div style="margin:0px;font-size:12pt"></div>
<div style="margin:0px;font-size:12pt">And I only received one signal<span> </span><span style="margin:0px;background-color:rgb(255, 255, 255);display:inline !important">quality</span><span> </span>value after that, this is completely silent.</div>
<div style="margin:0px;font-size:12pt"><br>
</div>
<div style="margin:0px;font-size:12pt">This seems logical (even I don't know why the refresh rate is set to 0 by default) and I manually set the refresh rate with mmcli -m any --signal-setup=30 but this doesn't change anything and the signal<span> </span><span style="margin:0px;background-color:rgb(255, 255, 255);display:inline !important">quality</span><span> </span>keeps
being not updated.</div>
<div style="margin:0px;font-size:12pt"><br>
</div>
<div style="margin:0px;font-size:12pt">I checked that via the signal quality in mmcli output which state in "cached" state while running mmcli -m any --signal-get gives info that are updated.</div>
<div style="margin:0px;font-size:12pt"><br>
</div>
<div style="margin:0px;font-size:12pt">Do you know where the problem came from (the 0 default refresh rate and the not updated signal quality) ?</div>
<div style="margin:0px;font-size:12pt"><br>
</div>
<div style="margin:0px;font-size:12pt">Thanks in advance for any help you can bring to me.</div>
