PATCH 1/1 rctest DUMP mode with data dump

Hello,

the attached patch extendes rctest.c with a cmd line switch -D, which writes the data recived in DUMP mode to stdout.

Install:
cd bluez-utils-2.21
patch -p0 < rcdump_2.21.patch
make distclean
./configure --enable-test
make

Why I made it:
For me it is usefull as a very simple client program, which waits for incoming connections and dumps the incoming data. It can be used from script languages like perl.

In real I receive mesurements from a sensor (bluetooth equiped with PicoPlug) out there, which wake up from time to time, send measure value via SPP to the host, where the pachted rctest runs and sleeps again.

sml@Amadeus:~> rctest -P 5 -d -D
rctest[12071]: Waiting for connection on channel 5 ... rctest[12072]: Can't get RFCOMM connection information: Protocol not available
(92)
rctest[12072]: Connect from 00:80:37:15:1A:A9 [handle 0, class 0x000000] rctest[12072]: Receiving ...
this is line the data payload
rctest[12072]: Disconnect: Connection timed out

Please give me feedback, if this is usefull for anybody else.

Hartmut
