<p>Hi, </p>
<p>I'm working on an application which utilizes 4 simcards connected to 2 Sierra Wireless MC7304 modems, to manage an internet connection across internet providers / country borders / etc. </p>
<p><span style="font-size: 12pt;">Simcards are</span><span style="font-size: 12pt;"> </span><span style="font-size: 12pt;">separated by a </span><span style="font-size: 12pt;">GPIO-pin (high/low) to change simslots.</span><br>
</p>
<p><span style="font-size: 12pt;">The goal is to disable a modem, set simcard in low-power-mode change the gpio-pin, set simcard in power-state-on and enable the modem, which will save time and prevent the modemmanager-interface from changing. </span><br>
</p>
<p><span style="font-size: 12pt;"><br>
</span></p>
<p>But, c<span style="font-size: 12pt;">urrently the only way I've found to change between simslots with libmm-glib/mmcli </span><span style="font-size: 12pt;">is to fully reset the modem after changing the gpio-pin with an AT!RESET.</span></p>
<p><span style="font-size: 12pt;"><br>
</span></p>
<p><span style="font-size: 12pt;">Case 1: the first simslot is empty the modem goes to state: FAILED => reset, </span></p>
<p><span style="font-size: 12pt;"><br>
</span></p>
<p><span style="font-size: 12pt;">Case 2: re-detect the new simcard after modem-low-power-mode needs a reset as well, </span></p>
<p><span style="font-size: 12pt;"><br>
</span></p>
<p><span style="font-size: 12pt;">first case is fine, we are not interested in using the empty simslot so that switch can be ignored after initialization, but changing between available simcards "on-the-fly" is one of the points of the whole system, so not
having to reset the modem is much preferred. </span></p>
<p><br>
</p>
<p><span style="font-size: 12pt;">an example I've been testing with is manually swapping a single simcard (see output below, sorry it's quite large) while manually powering down the modem/simslot, using qmicli along with mmcli and at-commands.</span><br>
</p>
<p><br>
</p>
<p>[NOTE]</p>
<p><br>
</p>
<p>we added <span style="font-family: Calibri, Arial, Helvetica, sans-serif, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;">--uim-power-down and <span style="font-family: Calibri, Arial, Helvetica, sans-serif, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;">--uim-power-up
to qmicli to switch the simslot-power on/off, and it's working as intended.</span></span></p>
<p><br>
</p>
<p>[/NOTE]</p>

<p>A working manual example is: </p>
