Hello everyone!
I’m using the Telit UE910-GL for a 3G connection and even though I can see it within the USB modules, I can’t connect to its network. It doesn’t show on ifconfig command…
Here are some terminal’s commands responses:

I think here is important to notice the cdc_acm instead of something like qmi_wwan.

From the examples above, we can see that the raspberry recognizes it and I’m also able to connect and send AT+COMMANDS to it.
picocom -b 9600 /dev/ttyACM0
- Manufacturer identification
AT+GMI
Telit
OK
- Model identification
AT+GMM
UE910-GL
OK
- Read command reports the PIN/PUK/PUK2 request status of the device in the form:
AT+CPIN?
+CPIN: READY
OK
- Set command enables/disables network registration reports depending on the parameter .
- (0,1) (the MODULE is registered)
AT+CREG?
+CREG: 0,1
OK
- Set command specifies PDP context parameter values for a PDP context identified by the (local) context identification parameter,
AT+CGDCONT?
+CGDCONT: 1,"IP","allcom.vivo.com.br","",0,0
OK
I think those are the main commands that I found around the sixfab tutorials… Also AT#ECM=1,0,"","",0 returns error all the time =/
I’ve also downloaded the Telit_Modules_Linux_USB_Drivers_User_Guide_r8 but I couldn’t find a solution for it…
Thank you for your time
