<div dir="ltr"><div dir="ltr"><div>Hello Alexander and people in the list,</div><div><br></div><div>Let me provide some additional information and new test log messages.</div><div><br></div><div>The problem I reported is improved one setp. Originally it was like:</div><span class="gmail-im" style="color:rgb(80,0,80)"><div> root at LEDE:~# mmcli -L<br> error: couldn't create manager: Timeout was reached<br></div><div><br></div></span><div>Now it is like:</div><div> root@LEDE:~# mmcli -L<br> No modems were found<br></div><div><br></div><div>I had to enable "dbus-utils" under "Utilities" of openwrt make menuconfig. So it seems that now mmcli talks with ModemManager at last. The problem now belongs to ModemManager not in the mmcli.</div><div><br></div><div><br></div><div>And I created the rule file you provided:</div><div><br></div><div># vim /lib/udev/rules.d/78-mm-custom.rules to fit to my modem:<br>ACTION!="add|change|move", GOTO="mm_custom_end"<br>DEVPATH=="/sys/devices/platform/1a0c0000.usb/usb2/2-1",<br>ENV{ID_MM_TTY_BAUDRATE}="115200"<br>DEVPATH=="/sys/devices/platform/1a0c0000.usb/usb2/2-1",<br>ENV{ID_MM_TTY_FLOW_CONTROL}="xon-xoff"<br>LABEL="mm_custom_end" <br></div><div><br></div><div>I wonder if these rule files are supposed to be provided from the modem provider.
