LimeSDRMini Octave example - waveformfile(.wfm) error

I tried to fit this example( for LimeSDRMini. We have error about wfm files.I noticed wfm files not supported by LimeSDRMini. Actually, I dont know what these files do. How can i figure this?
Thx, best.

The workshop is designed around the larger LimeSDR USB and as you have discovered, the LimeSDR Mini is not capable of playing waveform files (due to it not having DDR memory like the larger board).

GNURadio has GFSK example for LimeSDRMini and we want to use octave with LimeSDRMini. For this we worked on source codes. We are using LMS_SendStream() function but we cannot get correct result. Any suggestion?
