Hello, I want to create a flowgraph in order to send a "Hello World" using my LimeSDR-Mini.
The thing is that I want to encode the "Hello World" using NRZ, Manchester, etc coding techniques, but I don't know if this is possible. Also I would like to modulate on FM, for example. But as the input from the WBFM Transmit block is a float, I don't know if my File source block could be a float or I should use a conversion block.
I hope someone can help, thanks in advance.
