EM7565 "no network service"

IoT Modules
1

I’m trying to get a new EM7565 module up and running. I’ve had it working in the development board in windows, I’ve also had my custom carrier board working with a different EM7565. With the problem unit when I do at!scact=1,1 I get :

"at!scact=1,1
+CME ERROR: no network service
"

On the other EM7565 module it works just fine.

I tried updating the firmware, but had no effect. Is there some other settings I need to change to make this work? It seems to connect under windows just fine so the module is obviously capable of working on my network.

Thanks for the help.

Issue is probably because problem modem is set to MBIM.

at!usbcomp?
Config Index: 1
Config Type: 1 (USBIF)
Interface bitmask: 0000100D (diag,nmea,modem,mbim)
OK

Change it to rmnet like the other modem:

AT!ENTERCND=“A710”
AT!USBCOMP=1,1,10D
AT!RESET

After reset, AT!SCACT=1,1 should work.

Brilliant! It’s working now. Thanks.

One small issue remains. On the original EM7565 the control port ( the one I send AT commands to) enumerated as /dev/ttyUSB2, on this one it is /dev/ttyUSB0. On both cards I get USB0 through USB2, but the ordering seems to have changed.

I have a script that runs on boot and sends the at!scact=1,1 command to the radio. Right now this script assumes the control port is the last of the /dev/ttyUSB devices added by the GobiSerial driver. Is there a way to determined which port is which without need to open and test each port?

Hi greg.wood,

Please change it to AT!USBCOMP=1,3,10D same as a working module:

<Config Type> : 3 Generic
<Interface bitmask>:  0000010D (diag,nmea,modem,rmnet0)

AT!ENTERCND="A710"
AT!USBCOMP=?
AT!USBCOMP=1,3,10D
AT!RESET
AT!ENTERCND="A710"
AT!USBCOMP?                                                                     
Config Index: 1                                                                 
Config Type:  3 (Generic)                                                       
Interface bitmask: 0000010D (diag,nmea,modem,rmnet0)                            
                                                                                
OK

/dev/ttyUSB2 is AT port.

That did the trick, thanks.
