Have a transmitter/reciever pair hooked up to two seperate boards. Each message I send is a Sync byte, then a Message Start byte, then an address byte, then an information byte. If I send the messages one at a time then the receiver gets the message about 1 out of 20 tries. If I send messages as fast as I can the receiver appears to be receiving most or all of them.
Also the transmitter works better when it sends hard coded signals instead of ones received through the USB cable from the computer.
Does anybody know how I can make sending single messages more reliable? Do you need any more info?
