Can not get IMSI and IMEI with AT commands
<p>I am using a raspberry pi to communicate with an SL8092 modem from Sierra. I am able to communicate with the device via the /dev/ttyUSB4 using minicom.</p>
<p>Sending AT commands returns the following answers:</p>
<pre><code>&gt; AT
&lt; OK
&gt; AT+CSQ
&lt; +CSQ: 30,99
&gt;AT+COPS
&lt;+COPS: 2
</code></pre>
<p>But when sending AT+CIMI or AT+CGSN, I am expecting to get the IMSI and the IMEI. Unfortunately it's not the case - the only answer I get is just &quot;OK&quot;.</p>
<p>Am I missing something?</p>
