	1 # RFCOMMd, a rfcomm daemon.
	2
	3 ## RFCOMM
	4
	5 RFCOMM is a sub standard of bluetooth, allowing serial communication via
	6 some bluetooth channel.
	7
	8 ## What is this?
	9
	10 The rfcomm daemon will offer some rfcomm service for any device and based
	11 on the id of the device, users can run different scripts, daemons or
	12 filters for serial link output.
	13
	14 This can be used in the most simple case to emulate some bluetooth
	15 printer, bluetooth-capable printing clients connect to, where the piped
	16 format is simply outputted to lpr(1). See the spirofilter script for how
	17 this can be done.
	18
	19 ## Installation
	20
	21 $ make
	22 $ make PREFIX=/usr install
	23 # Copy over init scripts from etc/* for your needs.
	24 # Copy over sample filters from filters/* for your needs.
	25
	26 ## Filters
	27
	28 A filter is a simple script, where the first argument is the rfcomm
	29 device, like /dev/rfcomm0. The script can then do whatever it likes on
	30 this pseudo tty. See the example filters for how to properly configure
	31 the device to your needs using stty.
	32
	33 Using this logic, you can use whatever daemon allowing serial
	34 communication as a filter script.
	35
	36 ## Types of Connection
	37
	38 Depending on how crappy someone implemented bluetooth, I observed
	39 following device behaviours:
	40
	41 1.) The device will connect, output content and then disconnect.
	42
	43 2.) The device connects and stays connected.
	44
	45 Since rfcommd does no child process management, which would be too much
	46 for it, you need to consider this for anything restarting rfcommd. Maybe
	47 in the future a better logic can be implemented.
