In what units is being measured the power received in rxstream::recv? I'm currently using B205mini-I and I was supposing that I was receiving Watts, but converting to dBW and then to dBm gives me a power level much higher than my spectrum analyser, even when my rx Gain is set to zero.

The values are linearly-proportional voltage readings that are *proportional* to the voltage at the antenna terminals. You'd need to use external calibration to determine their meaning in absolute power units like dBm. SDRs deliver *voltage* samples, not *power* samples. If you want to determine the power level in a stream of samples, then you could compute AVG(I*I + Q*Q) over whatever averaging interval is appropriate in your application.
