AT^BAND_PREF returns ERROR on MV31-W modem | Thales IoT Developer Community

September 3, 2021 - 2:56pm, 993 views

Hi,

I have been trying out sending AT commands to MV31-W modem. Most commands are working, however I am unable to enable/disable bands using AT^BAND_PREF.

Here are some of my outputs :

at
OK
at+cpin?
+CPIN: SIM PIN

OK
at+cpin=****
OK
at+cfun?
+CFUN: 1

OK
at^slmode?
^SLMODE:1,4

OK
at+cgdcont?
+CGDCONT: 1,"IPV4V6","internet","0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0",0,0,0,0

OK
at^band_pref?
ERROR
at^band_pref=nr5g,2,71  
ERROR
at+cops?
+COPS: 0

OK
at+cops=1,2,"20815"
OK
+cops: 1,2,"20815",2      

OK

I was wondering if the version we are using might have to be updated...

Here is the version of our MV31-W module :

at+skuid
HW Revision : V065
SW Revision : T99W175.F0.0.0.3.4.GC.003

OK

Thank you in advance for your answer,
