BG95M3 Not Receiving SMS

IoT Modules LPWA Module
1

I am working my way through integrating the BG95M3 into Android (7.1.1) RIL.

As of now the RIL is connecting to the modem, establishing a PPP connection that works within Android API and I can send SMS using Android API.

My problem is that it never receives SMS. When I was manually connecting to the USB I could send and receive SMS, and I would receive URC for new SMS.

Are there special setting for the RIL that I need to include for Android to be able to receive SMS?

Here is my radio log

I can see it setting the URC port to UART1

AT+QURCCFG=“URCPORT”,“UART1”
OK
AT+QCFG=“CMUX/URCPORT”,1
OK

As a side note, I see a ton of these errors in the radio log:

AT+CRSM=192,28478,0,0,0,“”,“3F007F20”
+CME ERROR: 100

Any idea what these are for?

Thanks!

There is no entry for telephony.sms.receive

I checked my config.xml and found:

<bool name="config_voice_capable">false</bool>
<bool name="config_sms_capable">true</bool>

Here is my networkAttributes from the same file:

<string-array translatable="false" name="networkAttributes">
     <item>"wifi,1,1,1,-1,true"</item>
     <item>"wifi_p2p,13,1,0,-1,true"</item>
     <item>"ethernet,9,9,2,-1,true"</item>
     <!-- BG95 Added-->
     <item>"mobile,0,0,0,-1,true"</item>
     <item>"mobile_mms,2,0,4,60000,true"</item>
     <item>"mobile_supl,3,0,2,60000,true"</item>
     <item>"mobile_dun,4,0,2,60000,true"</item>
     <!-- BG95 Add end-->
</string-array>

I was given Quectel_Android_RIL_Driver_V3.3.32 by support to use, should I use Quectel_Android_RIL_Driver_V2.9.6 instead?

Also, I am curious, do my PPP chat files get used at all by the RIL? I ask because right now my quectel-ppp script uses /dev/ttyUSB2 (I was testing out PPP and my modem was only attached to USB at the time, now it is attached to UART).

Thanks for the help!
