RX_OFDM.grc not working on LimeSDR

Projects LimeSDR

Hi,
I have been trying to adapt the rx_ofdm.grc example for binary file transfer, although nothing appears on the RX side when I connect the LimeSDR sinks.

Has anyone been able to successfully implement this? If not any suggestion how should I proceed to accomplish a BPSK/QPSK file transfer using the LimeSDR and the GnuRadio?

Thanks in advance

Hi @andremartins4,

I’ve been trying to make it work with LimeSDR mini but failed. Have you found any solutions yet?

I was wondering where this rx_ofdm.grc was from, and I think I found where ? https://github.com/gnuradio/gnuradio/tree/master/gr-digital/examples/ofdm

Have you tried asking for help with gnuradio on the gnuradio IRC channel ? https://wiki.gnuradio.org/index.php/Chat ( Typically IRC is slower than some snail mail. Basically ask a question and hang around for 24+ hours for a reply, somebody in any timezone will eventually see the question and respond ).

Thanks @mzs for the IRC recommendation. I thought to check with LimeSDR community first :slight_smile:
