On the video you see a browser page talking morse code to a cheap walkie-talkie using only a normal audio cable.
In theory this shouldn't be possible because the audio is processed by the radio chip without access by the CPU.
In practice here we are. What is this useful for? Well.. now you can basically use your browser to send and receive text messages without a fancy LoRa device.
