RF Link 4800bps Receiver & Transmitter

hi,
i purchased rf link 4800bps receiver & transmitter spark fun.

i have working except how determine when transmitter powered , wait until has established link receiver before running code on receiver?

code: [select]

void loop(){
incomingbyte = rfserial.read();
serial.println(incomingbyte, dec);

if(incomingbyte <30){
   digitalwrite(red, high);
   digitalwrite(blue, low);
   digitalwrite(green, low);
 }
 else if(incomingbyte >30 && incomingbyte <40){
   digitalwrite(blue, high);
   digitalwrite(red, low);
   digitalwrite(green, low);
 }
   else if(incomingbyte >40){
   digitalwrite(green, high);
   digitalwrite(red, low);
   digitalwrite(blue, low);
 }

incomingbyte = 0;

}

im thinking ill need have sort of system i.e

send 000011000011000011 @ start @ other end?

i have no idea!!!

thanks

thanks

hi,
when using 1 way transmission can't know if there receiver. same way fm radio station doesn't know if listening.

i suggest if not want read partial data, set header , tail each transmission packet , on client side write code match full packet.

another option setting delay between packets client try sync transmission.
