Brad,
Try usimg sdptool browse XX:XX:XX:XX:XX:XX --l2cap (some phones do not
implement Public Browse Group which is used for discovery by default)
and if this does not help for some phones you have to ask for specific
profiles to get an answer (new Motorola's): sdptool search --bdaddr
XX:XX:XX:XX:XX:XX DUN for an example.
Regards,
Victor.=20

Subject: [Bluez-devel] sdptool fails with ppc6700
Hey
Is this a known issue? sdptool browse won't return anything with this
phone from sprint. I eventually found it would do DUN on channel 4 by
experimenting.

Do you have a "byebyemoto" workaround I can try out?

I only have the samsung i730 currently. So it will work for a while and
then drop the connection when I do something that saturates the link. Is
it useful to see the output of the older hcidump? The capture ends in:

show me the "hcidump -X -V" for that problem. I think that I know what
it is and I titled it ByeByeMoto. I've seen similar things on my new
RAZR V3x.

thanks... the l2cap scan didn't help, but searching specifically for DUN
did.
The phone still locks up whenever I try to max out the connection so
it's going back unless there's an easy fix. Maybe it's some kind of bad
interaction between bluez and pocketpc. :(
