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
OKThank you in advance for your answer,

Hello,
It is possible that your version does not support this command. It wasn't supported in some older versions yet. Your firmware is not new. I think that you need to contact your technical sales person of supplier for the firmware update.

In case it helps as a reference: works for me with this firmware:
at+skuid
HW Revision: V065
SW Revision: T99W175.T41.1.0.0.8.GC.004
OK
