I read in the internet that it is possible to connect the tomtom go gps to a
computer via bluetooth as a serial connection therefore allowing a gps

If I

But trying to connect it to a serial device:
victor$ rfcomm_sppd -a tomtom -t /dev/ttyp6
rfcomm_sppd: Could not obtain RFCOMM channel: Attribute not found
How can I make it?
I don't see RFCOMM in the list above. Here's what I do (for my Rikaline
bluetooth gps):
hccontrol -n ubt0hci inquiry
gives me something like:
Inquiry result, num_responses=1
Inquiry result #0
BD_ADDR: 00:00:00:00:67:4f
Page Scan Rep. Mode: 0x1
Page Scan Period Mode: 00
Page Scan Mode: 00
Class: 00:00:00
Clock offset: 0x44da
Then:
sdpcontrol -a 00:00:00:00:67:4f browse
Gives:
Record Handle: 0x00090001
Service Class ID List:
Serial Port (0x1101)
Protocol Descriptor List:
L2CAP (0x0100)
RFCOMM (0x0003)
Protocol specific parameter #1: u/int8/bool 1
Then:
rfcomm_sppd -a 00:00:00:00:67:4f -t /dev/ttyp6
and in another xterm:
$ sudo cu -l /dev/ttyp6
Connected
