Forgot to mention, you could get a Bluetooth to RS-232 module which
include every protocol in the module, and you don't need to write
anything, just plug'n'play, it will communucate throuth virtual com
port, but the module isn't cheap, and some cheaper modules the data
transfer rate is not fast. Last time I saw a Bluetooth to RS-232
module which can do a fast transfer, but it cost more than $60.
