Instruction format
Description
C5+C5+C5+frqH+frqL
In configuration (M0=1,M1=1,M2=0), send the command (HEX format) to the serial port of the
module: C5 C5 C5 frqH frqL, where frqH is the byte with high configuration frequency and frqL is
the byte with low configuration frequency. For example, if the band is 915M, C5 C5 C5 03 93 must
be sent. If it is configured in the 868M band, C5 C5 C5 03 64 must be sent. Read the current
frequency band send: C5 C5 C5 00 00, return the string 868 or 915. The change takes effect
immediately and is saved after power failure. Note that this instruction is only used for frequency
selection, and the actual operating frequency setting needs to be determined according to register
4[CHAN] in Section 7.6.
