Hello,

My PC is installed with Win XP SP2. I already made all installation workaround I found on internet to avoid problem with SP2 bluetooth driver. I delete all .inf bluetooth SP2 drivers and I have reinstalled my WIDCOMM driver.
The bluetooth device I want to use is a credit card reader (serial over bluetooth).
I can dedect my PC from the device and I can do the pairing.
After the pairing I have to establish the serial connection from the BT device, but when the device tries to connect to the PC the bluetooth driver on the PC displays the message "Error in pairing with device, Reason : Authentication failed, try pairing again".
At this time I can try to pair again and the pairing will be OK but I will always get the same message when I will try to connect.
It's like if the bluetooth driver is forgetting the pairing key or the pairing with this devive but I can see my creditcard reader in the bluetooth place. Rem . my PC is a Fujitsu with an integrated BT chip.

Did you have this problem??

Thanks in advance for our answers

Alain.
