Bluetooth Arduino Master and Slave Code

I have an Arduino Uno and Arduino Nano. I paired the HC-05 bluetooth modules and have the wiring diagram done. I need the Arduino Nano (Master) to tell the Arduino Uno (Slave) to turn on and off a relay switch using a simple limit switch. Fairly simple. I imagine someone that knows what they are doing could figure it out pretty quick. If limit switch button is pressed, relay turn on and if button is released then the switch turns off. I can resend files if needed at higher resolution. Again, I just need the Master and Slave code.
