Hi Marcel,

Thanks for your help. I know it may be irrelevant to ask this......but I have no other way! This group seems to be the only one where I can get a bit help.

1. I want to know the golden receiver power range (GRPR) of the bluetooth dongles I am using (specifically the upper & lower threshold). From your reply, I guess it should be implemented in the chips (BlueCore4-Ext or BlueCore4-ROM) and so will be a chip paramter. Should reading the data-sheets of those chips help me in finding their Golden Receiver Power Range (i.e. the upper & lower threshold level)? Or any other way to find it?

2. Is Link Quality (LQ) also a chip-parameter? Is the link quality algorithm same for all CSR chips (the one posted in your website)? How could you find that algorithm?

3. Does the power-control (stepping up or down of power) vary from chip to chip?

4. What's the main purpose of the driver (Toshiba or Level1 etc.)?

Thanks in advance
Mahtab

I ended up with dongles from Level1 and Toshiba. All of them were
BlueCore4-External, but it seems nowadays they only use BlueCore4-ROM
chips to reduce the costs.
