Re: [Bluez-users] Power level & Scan Timing

[Rafael Vidal Aroca <rafael@3wt.com.br>]

    With Rolf suggestion, i decreased the discovery time to about 5 
seconds using lenght 2.

    Now about the transmit/receive power, i know we can see what is 
set....but the windows software allows us to controle low high or 
medium...and as i understood from this mail this kind of configuration 
can not be set with bluez.
    Is it correct or is there a way to change the power level?

again, thanks.
Rafael.
