Bg951gl setting to LTE band 20

IoT Modules LTE Standard Module
1

I’m trying to set “LTE BAND 20” for module BG951A-GL.
I used recommended sequnce, but just on command anwer OK, others ERROR.
AT+CFUN=0
OK
AT+QCFG=“nwscanseq”,0203,1
ERROR
AT+QCFG=“iotopmode”,0,1
OK
AT+QCFG=“band”,0,0x80000,1
ERROR
AT+CFUN=1,1
OK

What correct sequence ? .
I used many efforts with using decimal vlaue fro band 20 : 524288 (=0x80000).
In some recomendation was recomended for band 2- value - 0x80 – also not working.

AT+QCFG=? get formula:
+QCFG: “band”,(0),(0-0x2000000000f0e189f),(0-200000000090f189f),(0,1)

Not so clear what i means.

Also why AT+QCFG=“nwscanseq”,0203,1 not recognizing – it’s fully correct to AT+QCFG=?
I used also “nwscanseq”,02,1 also answer is ERROR.

In some recomdation wrote that should be configured with CFUN=1
I used it – the same effoect..

Can you help me with correct sequence for set BG951A-GL to LTE BAND 20 ?

I’ve solved problem :

Problem was just in those CR and LF symbols in end of line.
Started to use just CR (0x13) and it’s started answerin fully correct and then:

AT+QCFG=“band”,0,80000,1
OK

+QNWINFO: “eMTC”,“24202”,“LTE BAND 20”,6300

Thanks to all for help !
