    Re: Getting RxLevel, RxQuality,Timing Advance Zero

    I have experienced the same thing and what I can tell you is that this functionality does not behave equally among all the Windows Mobile devices, in some devices the RIL_GetCellTowerInfo call does not provide all the information you need.

    In some cases the RxLevel and RxQuality can only be retrieved during a call. And it seems that in some devices this information is never available. I am not sure but I think it happens due firmware bugs or some restriction enforced on the platform by the manufacturer.

    I recommend you checking the dwParams that you receive back from the RIL_GetCellTowerInfo call to determine the availability of the values you are looking for. In your case you should expect the RIL_PARAM_CTI_RXLEVEL, RIL_PARAM_CTI_RXQUALITY and RIL_PARAM_CTI_TIMINGADVANCE bits from the dwParams to be active.

    Good luck!
