13.2.4 Dynamic routine
If the method above works, you are all set and done. I started out that way and everything worked great for a while. Then all of a sudden I was unable to connect. It turned out that the DUN channel on my phone had changed!?! Instead of 4 as in the example above it showed up as channel 2, and later on as channel 3...
The statical configuration done by editing the rfcomm.conf file cannot handle this confusion. Instead I needed to dynamically decide which channel my phone used for the DUN service today and bind to it.
This is done in a simple shell script, that is called just before I intend to connect. Personally, I use Kppp and find it great for both modemtomodem dialups and GPRS connections. So, I have configured KDE to call my script just before Kppp is opened.
First I was a bit suspicious about this method to work all the time, but I have not had any trouble this far and I have been using it for years now. You may find a printout of the script in Appendix C, or download it from http://ferrari.databa.se/3400/f8/dunbind.sh. Obviously, you will need to change the name of the bluetooth device, BTNAME, and maybe the port to connect it to, RFPORT. Once that is done you may test run it:
#wget http://ferrari.databa.se/3400/f8/dunbind.sh
#chmod +x dunbind.sh
#./dunbind.sh
