Hi
The boards are fixed to the 433 868 or 915 MHz bands
The properties dialog let you move the frequency a small amout (430.2425 to 439.7550) MHz for example with the 433 Board.
This is done by moving the slider.
Both Rx and Tx need to be set to the same frequency to work correctly.
Ive attched a simple half duplex Tranceiver flowchart.
Just load this into both systems
Pressing a key on one system will show on the LCD on the other system.
They wont both transmit at the same time though.
The boards only work with the professional version of flowcode
