HI , I have a peculiar problem and observation , can anyone help?
I have TRUST bluetooth usb dongle and bluegiga module working on an embedded controller. The usb dongle is coneected to the PC.

At about 2 meters, in two PCs where the dongle is conected, the bluetooth application works properly without any problem continuously even when testd for an hour,

whereas in  2 other PCs there is data error even within about 2 mintutes of operation.

I am not able to understand what difference PCs make to bring about this?
situation. I will be obliged to take guidnace from anyone who knows better and has a clue. The devices are Bluetooth vr 2.00 EDR categories.

Thanks in advance,  Murali :
