Change Tx Bluetooth Linux No Effect

I would like to change the signal strength of my bluetooth device using linux command line (ubuntu 14.04).

I have found that I need to use the command

sudo hciconfig hci0 inqtpl


to change the signal strength but it's not working




sudo hciconfig hci0 inqtpl


gives me

and with hcidump

enter image description here

sudo hciconfig hci0 inqtpl 2


gives me

enter image description here

Using the command again

sudo hciconfig hci0 inqtpl


Gives me exactly the same thing than the first time. Nothing changed.




The command

sudo bccmd psget 0x0017


gives me

Unsupported manufacturer





Thank you for your help buddies

Answer

So after checking with the manufacturer, it seems that the bluetooth we use is a class 2 bluetooth. Despite it should be class1!
