This looks more useful:

Radio Frequency HC-12. Arduino. Bluetooth HC-06

2.- App. Bluetooth. Arduino. App sends information via Bluetooth to the Arduino. Arduino transmits that information through the HC12. There is feedback from the Bluetooth module (but not from the receiving HC12). [hc12_17] arduino_bluetooth.ino #include <SoftwareSerial.h> SoftwareSerial HC12(10,11) ; // TX to pin_10. RX to pin_11 of Arduino. SoftwareSerial BT(2,3) ; // TX to pin_2. RX to pin_3 of Arduino. String texto; void setup() { HC12.begin(9600); BT.begin(9600); } void loop()…
