<p class="MsoNormal">Hello all,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Our device is running ModemManager v1.4.6 against a Telit HE910-D modem (rev. 12.00.024). We’ve been quite successful<o:p></o:p></p>
<p class="MsoNormal">in expediting data transfer via IP through the cell network (no problems there), but we’re having considerable difficulty<o:p></o:p></p>
<p class="MsoNormal">getting SMS messages to be received by the device. The signal strength being measured looks reasonable and since IP<o:p></o:p></p>
<p class="MsoNormal">connectivity is quite reliable I don’t think it’s RF-related.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’ve been running ModemManager in debug mode and using mmcli.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The issue I’m seeing is when the modem is <u>enabled</u>, ModemManager appears to be properly configuring the HE910-D
<o:p></o:p></p>
<p class="MsoNormal">for SMS handling (I see the <i>AT+CNMI=”<span style="color:#00B050">2,1,2,1,0</span>”</i> command being successfully executed to set-up new message indication<o:p></o:p></p>
<p class="MsoNormal">handling and the default message storage is properly selected). Running the
<i>AT+CSMS?</i> command shows the mode is<o:p></o:p></p>
<p class="MsoNormal">capable of sending/receiving SMS messages (as does <i>AT+CSMS=0</i> and
<i>AT+CSMS=1</i>).<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">However, immediately after I successfully <u>connect</u> to the AT&T “i2gold” APN (<i>mmcli –m 0 –simple-connect=”apn=i2gold”</i>),<o:p></o:p></p>
<p class="MsoNormal">I then re-query the New Message Indications configuration (AT+CNMI?) and the result is “<i><span style="color:red">0,0,0,0,0</span></i>”.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">My question to the group is: Do you think it is the AT&T network that is causing the change in the New Message Indications<o:p></o:p></p>
<p class="MsoNormal">configuration in the HE910-D?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Any help/ideas would be appreciated. I’ve attached a <span style="background:yellow;mso-highlight:yellow">
highlighted</span> log to perhaps help illustrate.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks in advance<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
