Thank you so much sir, out of all the HC-05 pairing forums and videos on the internet, you are the only one who solved my problem!!!

[@Manon-xs2fj]

thank you for the video (and the link to the code :) ) . Where do you find the Slave adresse that you put in the master's program?

[@nicolasguanoluisa552]

you need to use the AT comand, AT+LADDR?, some HC-05 give you this ERROR(0), i use this code to use the AT code:#include SoftwareSerial BTSerial(2, 3); // RX | TX void setup() { Serial.begin(9600); BTSerial.begin(38400); Serial.println("Sending AT+LADDR command to HC-05..."); sendATCommand("AT+LADDR?"); } void loop() { if (Serial.available()) { BTSerial.write(Serial.read()); } if (BTSerial.available()) { Serial.write(BTSerial.read()); } } void sendATCommand(String command) { BTSerial.println(command); delay(1000); while (BTSerial.available()) { Serial.write(BTSerial.read()); } }

Hi, can I use the same device as Master to receive a command (e.g. swtch on a motor) from a different device like a remote controller and then translate that command in an analog signal (e.g. open the circuit to power the motor)? Thanks.

Which type of arduino is it

arduino nano

when i saend a message its just giving ???? mark

[@RNEI_DarshanM]

In tht case chane ur baud rate

[@danger0679]

Same here. Have you figured it out ?

[@arduinobasics5556]

@@danger0679 yah i solved it interchange TX and Rx on both Arduino and it will work For me it worked I used this video to make gesture control car But there is some problem configuring adxl345 Do you have any idea about its code

[@danger0679]

Thank you very much for responding. I will do as you suggested. I am just beginner in arduino, but in future if I come across any solution to the code you're getting I will keep you posted.
