Note: if automatic band selection is enabled(AT#AUTOBND=2) then read
command AT#BND? will report followed setting of band configuration.
Band configuration for HE863 family is as followed
HE863-NAx(GSM QUAD, FDD II / V)
HE863-EUx(GSM QUAD, FDD I / VIII)
HE863-AUx(GSM QUAD, FDD I / V)
AT#BND?
Read command returns the current selected band in the format:
#BND: <GSM band>, <WCDMA band>
AT#BND=?
Test command returns the supported range of values of parameters <GSM band>
and <WCDMA band>.
Note: the range of values differs between modules
3.5.5.1.42. Automatic Band Selection - #AUTOBND
#AUTOBND - Automatic Band Selection
AT#AUTOBND=
[<value>]
Set command enables/disables the automatic band selection at power-on.
