Hello,
Thanks Marcel for you earlier reply. I am new to
Bluetooth programming.
I am trying to make RFcomm connection with Motorola
HS850 through a DBT120 dongle. I am using linux
2.4.21-40 kernel and bluez 3.1 .
I see that the rfcomm connection gets disconnected
immediately. Is this how it is supposed to work? I
have pasted hcidump below. Pls let me know. thanks,
Manoj
