Hello,

the connection to my bluetooth modem doesn't work very reliable. When I connect successfully, "hcidump -V -X" looks like this:

Sometimes it's enough to restart the bluez-utils Ver 2.15 (hcid & sdpd), but in other cases I need to reload these kernel modules:

Hi Raphael,

Quoted 2 lines

the connection to my bluetooth modem doesn't work very reliable. When I connect successfully, "hcidump -V -X" looks like this:

the support for a 2.4 kernel is deprecated. Move to the latest 2.6 kernel and use the latest hcidump. I am not looking at hex numbers.

Regards

Marcel
