I am trying to connect a bluetooth GPS iPAQ Navigation System Model# BT-308 to my gumstix. When I boot the gumstix here is what I see:
(I snipped out the bluetooth related info from the boot sequence) ....

Scott,
Did you get the GPS working? I have recently fought through some of this. The general methodology I used was: See the Bluetooth GPS using hcitool commands (This you have accomplished) Create an rfcomm connection to the device. Check you /var/log/messages to see the various status information or use "hcidump" to see the raw communication stream. Then you can "cat /dev/rfcomm0" to see the raw GPS stream. The thing that gave me fits was that I had to run a passkey program on my gumstix to provide a passkey to the GPS device. I used: passkey-agent -default 0000 & Once I could see the raw NMEA code on the /dev/rfcomm0 device, I installed Gpsd on /dev/rfcomm0 Then, I found cgps a useful serial based program to begin the real work. It provides an update without watching the raw data - unless you are into that "Matrix" sort of thing. I do find it interesting that you can begin to discern the items of interest from watching enough raw data... Mike -----Original Message----- From: gumstix-users-bounces@...
