[Bluez-devel] Widcomm BlueConnect and Bluez

[Didier Alves]

Hi,

Does anybody tried to connect a TDK CSR usb dongle using bluez and a PDA
with Widcomm Blueconnect 3.0 springboard? I can create rfcomm links
without any problem but after some time (2-10 seconds) the springboard
stop receiving data. The problem occurs when I try to send a stream of
data from the PC with bluez. It looks like there is a buffer overrun on
the receiver. I know that the problem is from the PDA but since that
Widcomm stopped working on BlueConnect, I can't get any help from them.
So if anybody has any ideia about what the problem is and how to resolve
it, please help.

Thanks.

Didier

what kind of PDA is this? What kernel are you using? Make a binary
hcidump and send it to us.

please run "hcitool info <bdaddr-visor>" (as root).

Don't use this. A kernel with my -mh patch is enough.

I use this version of bluez kernel because I need to make some changes in
bluez modules (qos parameters...). Can I make these changes with mh?

Thanks.

so go with my -mh patches and if you have changed something and you want
me to include it into the mainstream kernel, post a patch to the mailing
list.
