rx_power with LimeSDR #89

Open ghost opened 3 years ago

ghost commented 3 years ago

I'm trying to work with rx_power scripts recently. For some reason, the csv file output is not correct in Ubuntu 16.04. However, it's working fine in Ubuntu 20.04. Unfortunately, changing the Ubuntu distribution from 16.04 to 20.04 is not an option for me at the moment. So, I need some suggestions and help to identify and fix the problem in Ubuntu 16.04

SoapySDRUtil --probe="driver=lime" finds the LimeSDR without any problem. Can someone points me in the right direction whether it's some soapy library issues or not? or rx_power is not compatible with ubuntu 16.04 ? Any suggestions are welcome

I added -d driver=lime options with rx_power command. This time got this error Error: bad retune at 101388888 Hz (4 of 3 attempts), r=-1, flags=0 (try increasing -S or -R). Error: reading stream -1
