Arduino. The HC-06 module does not respond to AT commands. What am I doing wrong?

Question

Arduino

Hello! I bought myself an Arduino Nano and HC-06 decided to try what and how. I connected this method.



Only I connected it to pins 10 and 11.
Uploaded the sketch

#include

SoftwareSerial BTSerial(10, 11);

void setup() {
BTSerial.begin(9600);
Serial.begin(9600);
delay(500);
Serial.println("Enter AT commands");
}

void loop() {
if (BTSerial.available()) {
Serial.write(BTSerial.read());
}
if (Serial.available()) {
BTSerial.write(Serial.read());
}
}

But when viewing the port monitor, I send the command, but nothing in response. What am I doing wrong?

Answer 1

1. Check installation.
2. Check arduino and code. To do this, turn off the bluetooth module and connect pins 10 and 11 to each other. If the code is correct, everything you send to the terminal should come back.
3. Check the bluetooth module. Connect according to your scheme, connect to the bluetooth using your smartphone and open the terminal on your smart phone. If the module is OK, the data from the computer terminal will go to the smartphone terminal and vice versa.
4. Switch the module to AT command mode. To do this, disconnect your smartphone from the module. NS-06 itself switches to AT mode in the absence of a bluetooth connection.

Answer 2

Swap rx and tx, confused, most likely
