Hc-06 bluetooth module wont connect

Using Arduino Project Guidance
#1

I’ve been trying to set up my Bluetooth module just to change the Baud Rate and the name.
I tried to change the serial baud rate to every one of them and when I try the AT command it won’t return anything in the Serial Monitor.

<I connected the Vcc to 5V, Tx to D10 and Rx to D11>
<I tried to connect Vcc to 3.3V as well>

Here is the Code:

#include <SoftwareSerial.h>

SoftwareSerial mySerial(10, 11); // RX, TX

void setup() {
 // Open serial communications and wait for port to open:
 Serial.begin(9600);
 mySerial.begin(9600);

 while (!Serial) {
   ; // wait for serial port to connect. Needed for native USB port only
 }

 Serial.println("Start Communicating");
}

void loop() { // run over and over
 if (mySerial.available()) {
   Serial.write(mySerial.read());
 }
 if (Serial.available()) {
   mySerial.write(Serial.read());
 }
}

Attache a proper wiring diagram. Those Skakespeare typ diagrams don't work. You connect and You try to connect, 5 volt, 3.3 volt...… Makes no sence.
Read "How to use this Forum" and post code using code tags.

Stop trying 3.3v and stick to 5v.
Have you tried initial ping "AT"?
Have you used the right command ? AT+BAUD8

#4

I did initialize "AT" but nothing shows up

#5

Note that the serial monitor should be set to "no line ending" at the bottom, and 9600 baud.

#6

Oh my god, IT WORKS! THANK YOU! But is there any reason why it has to be no line ending?

#7

I've no idea, and note the the HC-05 does require a line ending.
