Cool project. I have a keyer exactly like that "somewhere".

Nice project. I may have to build one myself.

Neat!

Although few suggestions for tx & Rx sides,

I think transmitter code needs to send the state of keyer only when the input the state change. Currently it is transmitting the state every 25ms continuously. It will also reduce the redundant lines as well.

you can use strncmp to compare the received payload against two char buffers with different sizes. If only one byte of data is checked, it makes sense to transmit 0 &1 and avoid using uint8_t buffer and charcopy of same size.
