Tengo 2 HC-05 conectados entre si, uno esclavo que es el del coche y el otro el maestro.
El código del coche se activa con letras pero lo que no se es como enviarlas con el maestro.
Aquí los codigos:

y el del maestro que no se como funciona:
#include <SoftwareSerial.h>
// se define al Pin2 como RX, Pin3 como TX
SoftwareSerial mySerial(0,1);// RX,TXvoid setup()
{//inicializa la comunicación serial
Serial.begin(9600);
}
void loop()
{
mySerial.write('f');
delay(2000);
mySerial.write('g');
delay(2000);
}
Lo que quiero es ponerlo con botones, pero intente probar a ver si arrancaba el motor pero no hace nada.
con el móvil probé el codigo del coche y funciona bien, el blutu esta puesto:
RXD BLUTU= TX1
TXD BLUTU= RX0
A ver si alguien puede ayudarme ya que soy un novato. Saludos!!!
