Do you have a start script for gpsd? Just add those lines to your start script, and you're done. You can either create a shell script to start gpsd, or better yet, have gpsd start in a boot script.

Look up info on init scripts. You can usually copy one for a different service, and modify it for your own needs.

is the sudo in the release command going to work?

If you're putting those in an init script, it will be run as root anyway and you can remove the "sudo" from that line.

here is my /etc/init.d/gpssamp.sh

Code:

#!/bin/sh
rfcomm release 4
rfcomm connect 4
gpsd -n /dev/rfcomm4

to put it there i used

Code:

cd /etc/init.d/

sudo gedit gpssamp.sh

sudo update-rc.d gpssamp.sh defaults
update-rc.d: warning: /etc/init.d/gpssamp.sh missing LSB style header
 System startup links for /etc/init.d/gpssamp.sh already exist.

sudo chmod +x gpssamp.sh

works just fine when manually started but wont do it on start

Code:

 sudo  /etc/init.d/gpssamp.sh
[sudo] password  : 
Connected /dev/rfcomm4 to 00:12:0E:80:D8:xx on channel 1
Press CTRL-C for hangup

then close terminal(bc i dont have a control key)

then i can run roadnav and it picks the reciver up

have a look at /etc/init.d/skeleton for a proper init script. That should give you a base to start from when creating your script.

the skeleton file looks really scary, after some searching I found a Start up script generator:

Also can I link to the script file from the sessions (System \ Preferences\ Sessions \ Startup Programs) menu?
