Hello, I am new to this Group.
Thank you for your recommendation to avoid using unsupported techniques. I am trying to obtain the signal strength seen by the G1 phone. As you had referred to, I have implemented a PhoneStateListener and onSignalStrengthChanged (int asu). It looks like I am seeing only a few returned asu values (e.g., 2, 6, 12 and 25). I believe that the mapping of asu to dBm is as follows: -113dBm + 2*asu. Therefore, it looks like the G1 phone is reporting dBm values of -109, -101, -89 and -63. Also, I see that the signal strength icon used by the G1 has four bars (I am assuming that each bar corresponds to one of the 2, 6, 12 and 25 asu values). Question: do you know if there is a supported way to obtain signal strength (either as an asu measure or a direct dBm measure) with a higher level of granularity (that is, for example, in single asu steps or single dBm steps)? Thank you in advance for any help or comments.
