Hi Gary,

The BF-888s uses the "h777.py" driver module. It is available in the CHIRP repository.

You may also be interested in looking at Baoclone. It is a basic command line programmer that supports the BF-888s among other Baofeng models.

Newbie here, so haven't found how to search topics yet.

I have a project where I have an arduino housed in an enclosure with a 
baofeng bf-888s. I want to be able to leave the radio on channel one, 
and program both pre-stored frequencies, as well as manually entered 
frequencies.  The arduino is tied to the audio in and out of the 
radio. I know enough about arduino coding to generate square wave 
output and detect square wave input, vary frequency of the data 
pulses, duty cycle, etc.

What I don't know is what is the protocol for sending a "code plug" to 
the BF-888s.  Anyone know where to steer me?  Mr Google doesn't seem 
to understand my question.
