Hey all,
Has anyone tried to transmit small audio using LoRa-SDR pothos blocks. I know LoRa is very slow protocol to transmit audio/image…but just curious to test…
This is the TX chain, that I created to fetch audio from UDP source and transmit it using LimeSDR mini
This is RX chain to receive the signal and retrieve the audio
On the receiver side, I saw garbage value in my UDP sink and but audio player doesn’t recognize it. My guess is, probably I need some error correction block to regenerate the audio packets…
Any suggestions or comments?? reference links for additional reading also welcome 
Happy Friday!!
