Read Frequency Agility Configurations - Command Code = 37
This command reads out the module’s Frequency Agility channel mapping
value.
The channel map value is one byte long and contains two parts. The high
nibble defines the number of channels out of the 4 available channels that
are used. The low nibble is a bitmap which defines which channel(s) are
being used. In this nibble, bit 0 corresponds to channel 0, bit 1 to channel
1 and so forth.
For example, the factory default value is 0x12. The high nibble is 0x01, so
one channel is being used. The low nibble is 0x2, which is binary 0b0010,
so channel 1 is being used.
The response parameter indicates if the command was successful (00) or if
there was an error (01).
