When the frequency-hopping quantity sets as 1, the module
works only at the fixed frequency (425M + CHAN *
0.5M ). Otherwise the module works at
(425M Hz+CHAN*0.5MHz+FHSS_nums*0.5M Hz).
-----------------------------------------------
This bit is used to the module internal pull-up resistor. It
also increases the level's adaptability in case of open drain.
But in some cases, it may need external pull-up resistor.
-----------------------------------------------
0 is recommended.
-----------------------------------------------
After turn off FEC, the actual data transmission rate
increases while anti-interference ability decreases. Also,
the transmission distance is relatively short.
Both communication parties must keep on the same pages
about turn-on or turn-off FEC.
-----------------------------------------------
The external power must make sure the ability of current
output more than 300mA and ensure the power supply
ripple within 100mV .
Low power transmission is not recommended due to its low
power supply efficiency.
