Hi All,
We Have EC200A-CN Quectel Modules,
On this Modules We want to have an Option for band selection as 3gonly, 2gonly, LTE only, LTE Band 1, LTE band 3, LTE Band 8, LTE Band 40, LTE Band 41,

Please Help on flow to switch from LTE to 2gonly(gsm) or 3gonly(wcdma) mode, or selecting the specific lte band.

i have tried AT+QCFG=band, but it didnt worked

AT+QCFG="nwscanmode",1

AT+QCFG="nwscanmode",2

What was the exact command you used, and what was the response to the command?

To configure the LTE bandmask to B3 and B41 only, for example, the command is:

AT+QCFG="band",0,10000000004

hi @snowgum ,
AT+QCFG=“nwscanmode”,1
this command seems to throw CME Error 50

Maybe “1” is not a supported value. What does AT+QCFG=? return?

Look for the “nwscanmode” line for the supported values.

According to 3GPP 27.007, CME error 50 is “Incorrect parameters” (section 9.2.1).

AT+QCFG=?

0 through 3 supported according to that. I have no idea what went wrong when you tried setting it to 1.
