Hi Everyone,
I am using two PC's, one consist of VIA mother board
and another one consist of Intel chipset mother board. I am having one
dongle of CSR chipset. In both PC's I installed Bluez(2.17).
First, I plugged the usb bluetooth dongle to VIA PC
and i used "rfcomm connect 0 <BDADDR> 1". It get connected and worked
fine. Then, I plugged the same dongle in the Intel chipset PC and used
"rfcomm connect 0 <BDADDR> 1". This is also working fine.
Again I did the First step. But now "rfcomm connect 0
<BDADDR> 1" fails with the following message:

Can't connect RFCOMM socket: Connection refused

At this time i am getting the following hcidump:
