The API is working - I can stream I/Q. As I understood the sample either I or Q is a number in the range [-2048, 2047]. So signal ith sample is (Ith + Qthj).
To get the power - I can simply calculate "I*I + Q*Q"
The maximum power that can be measured is basically 2048*2048*2

1- How can I get the actual power measured (dBm). I'm not asking for perfect calibrated level
