WARP Project Forums - Wireless Open-Access Research Platform

hi,

I have problems in reading RSSI of radio 2 and radio 3 by software control. I built up the project with 2 radio cards (radio 2 and radio 3) by project-base system builder. I inputed sinesoid signal into the WARP and tried to control them by software. I am sure that I can control the CenterFrequency, RxEnable, RxLnaGain and  RxVGAGain correctly. But when I attempted to read the RSSI of both cards, the values were strange. For example, radio 2 is 899 and radio 3 is 4. And from chipscope, I could see that both signals of the radio cards were strong. And the values would not change even I readed hundreds of times with centern interval (100us) between every two read.

My question is that when I controled the RxEnable, RxLnaGain and  RxVGAGain by software, I ran the SoftControlEnable functions for the corresponding signals. But for Rssi control, I did not find the function for its SoftControlEnable. What should pay attention to when I attempted to read the RSSI by software?  Do I need to use the function of WarpRadio_v1_RssiHighBandwidth?

Thanks a lot,
