I am trying to control the pin output (high/low) on a RN42XVP-I/RM module, by sending commands from a Bluetooth Mate Silver controlled by an arduino pro mini.
I have connected both modules to my PC and removed the need for authentication (SA,0 , R,1).
I can connect the devices, but I am unable to put the slave module into command mode and then send commands to change pins high and low (s*,0400 and s*,0404).
My code so far is below. This connects the devices, as shown by a constant LED on the slave module, but once connected, I cannot work out how to put the slave device into command mode and control the pin output. Any help would be great!
Serial.begin(115200); // Begin the serial at 115200bps delay(100); Serial.print("$"); // Enter command mode delay(100); Serial.print("$"); delay(100); Serial.print("$"); delay(100); Serial.println("SM,1"); // Set to master delay(100); Serial.println("C,00066612345A"); // Connect to other bluetooth device delay(100);
