I’ve run into similar issue with mine LimeSDR Mini V2. Zack suggested that with the new LimeSDR both RX and TX channels are to enabled even only for RX-only applications.
If you add
if (LMS_EnableChannel(device, LMS_CH_TX, 0, true)!=0) // Fix for v2
error();
before //Enable RX channel
in singleRX.cpp
and recompile you should see proper streaming going on.
I’ve submitted a PR to the LimeSuite now with this change. Hopefully it will can be landed soon, or some alternative/better fix will land, so that we all will have better out-of-box experience with the LimeSuite
