Hi guys, i made an app that meassures the signal strength using the GetSignalStrength function. How can i convert the the result in dbms? What kind of units does this function counts? I'm getting values in a range of 15-20.
Any suggestion?

It depends on the phone you´re using. I´ve seen values from 15 to 20 only on an SX1 yet. On a 6600 I get values from 40-90.

Yes mate i'm getting these values on an SX1.I don't know about 6600 but i can try it.
So,what i have to do?
Celltrack dislays signal strenth in dbms in all cell phones. How they do it if it depends of the cell phone?
Tnx for your answer.

i found only this

(dBm) = (-113) + (2 * CSQ)

is this correct?
