Hi all,
my ipaq 3870 (with a built-in bluetooth device) is running Familiar Linux
0.8.2 with OPIE, i would like to use it with a GPS device (Nemerix BT77
chipset). I was able to get NMEA output time ago, now i'm trying again but
maybe i'm missing something - so please tell me where i'm wrong:

root@h3600:~# cat /dev/bluetooth/rfcomm/0

blank. nothing, no output. Time ago with the same O.S. version i was able to
see the NMEA output, so i used gpsd and a navigator. CTRL-C and...

root@h3600:~# rfcomm
rfcomm0: 00:08:1B:8C:3F:A2 channel 1 closed

where is the mistake? any help is appreciated. I have not the hcidump tool
for my PDA (StrongARM cpu).

I think the devices are paired: isn't it an operation that i have to do only
once? I say this cause i was able to use the GPS receiver without problems.
Now i'm trying several version of Familiar (from 0.8.2-stable to
0.8.3-snapshots and release candidate) without luck.

How could i pair again the devices?

what does this do:

# l2ping 00:08:1B:8C:3F:A2


I would also look if they actually are paired
