<div class="WordSection1">
<p class="MsoNormal">Hello,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have MM version 1.6.4 running on Linux and I am using it to communicate with a Telit LE910 V2 over MBIM and AT.<o:p></o:p></p>
<p class="MsoNormal">Along with MM I have running my own process that sends and receives AT commands over one of the serial interfaces (ttyACM0).<o:p></o:p></p>
<p class="MsoNormal"> -------------------------<o:p></o:p></p>
<p class="MsoNormal"> Hardware | manufacturer: 'Generic'<o:p></o:p></p>
<p class="MsoNormal"> | model: 'MBIM [1BC7:0032]'<o:p></o:p></p>
<p class="MsoNormal"> | revision: '20.00.504'<o:p></o:p></p>
<p class="MsoNormal"> | supported: 'gsm-umts, lte'<o:p></o:p></p>
<p class="MsoNormal"> | current: 'gsm-umts, lte'<o:p></o:p></p>
<p class="MsoNormal"> -------------------------<o:p></o:p></p>
<p class="MsoNormal"> System | device: '/sys/devices/platform/soc/soc:internal-regs/d005e000.usb/usb1/1-1'<o:p></o:p></p>
<p class="MsoNormal"> | drivers: 'cdc_acm, cdc_mbim'<o:p></o:p></p>
<p class="MsoNormal"> | plugin: 'Generic'<o:p></o:p></p>
<p class="MsoNormal"> | primary port: 'cdc-wdm0'<o:p></o:p></p>
<p class="MsoNormal"> | ports: 'ttyACM3 (at), cdc-wdm0 (mbim), wwan0 (net)'<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Apparently MM fails reading packet statistics from the Modem and this happens periodically. I see the following error -<o:p></o:p></p>
<p class="MsoNormal">ModemManager[1949]: <warn> Reloading stats failed: OperationNotAllowed<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I suspect that MM’s periodic stats request(assuming this is over MBIM) is interfering with my AT requests over ttyACM0, which fail occasionally (i.e I don’t get responses to AT commands send over ttyACM0 ocassionally).
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I would like to know if there is a way to configure MM to prevent polling for stats and if it may interfere with using one of the serial ports independently of MM?<o:p></o:p></p>
<p class="MsoNormal">Please let me know if you need more information.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks,<o:p></o:p></p>
