an AT command to set specific bands:

AT!ENTERCND="A710"

add new band groups:

AT!BAND=10,"Only B2",0,0000000000000002 
AT!BAND=11,"Only B4",0,000000000000008
AT!BAND=0F,"B2 and B4",0,000000000000000A

set to only B2 and B4 by selecting group 0F:

AT!BAND=0F

AT!RESET

Please let me know if I missed anything that you might need, thank you in advance.

Hi @PR-NCE , there is a big problem with adding support for Sierra Wireless modems. Through the band grouping mechanism, I can't easily read and set the bands.

[PR-NCE]

Hi @4IceG, are you open to the idea of adding support for sierra modems if I or someone else write the code for it? and can you please point me to the file in your repository that should be modified (to save me time as i haven't looked to see how you programmed this luci app) e.g. the exact part that is responsible to handle band looking for Quectel modems.

[4IceG]

Hi @PR-NCE , I'm open to code. If you add simple code that is compatible with the modemband package.
https://github.com/4IceG/luci-app-modemband/tree/main/modemband

My package for LuCI is unimportant, all operations are done by modemband package, I only made the gui for the user.
For example, for Quectel EM12-G

Hi,
could you again show output of:

AT!ENTERCND="A710"
AT!BAND=?
AT!BAND?
