I’m experimenting with OFDM implementation with LimeSDR-mini. I found sample gnuradio examples (rx_ofdm.grc and tx_ofdm.grc) under /usr/share/gnuradio/examples/digital/ofdm/ directory. Simulation mode works fine, then I replaced the source and sink with LimeSDR blocks. However, the receiver file is always 0 kb with no data.
Has anyone tried this with limesdr? Could you please give me some suggestions to make it work with the hardware.
