Hi all.
I am trying to connect my linux laptop via a bluetooth dongle with a modem
(typhoon 56k Bluetooth modem). With a windows-system this combination works
fine.
With "hcitool scan" the modem is found correctly, but a simple
echo "ATZ" > /dev/rfcomm0 fails with an authentication error.
I have read several documentations about bluetooth and linux and followed
(hopefully) exactly the steps, that were described there. But I still get the
same error every time i am trying to connect to the modem.
So, please help me........
Here comes my configuration and the output of hcidump, hcid, bluepin,
hciconfig. If you need any further information just ask for it.
Thx and best regards,
Olli.
