You can change the baud rate of the HC-05 by using AT commands.

Use:

<pre><code> AT+UART=57600,1,0
</code></pre>

here is a <a href="http://dronehitech.com/change-baud-rate-bluetooth-module/" rel="nofollow">tutorial</a>

If it is the full code then you sending not printed characters. And also after you will get i=127 you will send characters from upper part of ascii table. And think what will happens when i>255. Try this code in loop:

<code>Bluetooth.println("this is test code")</code>

instead of writing <code>Bluetooth.write(i);</code>

From <a href="http://blog.oscarliang.net/multiwii-bluetooth-change-baud-rate/" rel="nofollow noreferrer">here</a>:

<blockquote>
 The bluetooth module baud rates are set by an hexadecimal index from
 ‘1’ to ‘C’. Indexes are: 1:1200, 2:2400, 3:4800, 4:9600, 5:19200,
 6:38400, 7:57600, 8:115200, 9:230400, A:460800, B:921600, C:1382400
 
 To set a default baud rate, enter this command
 
 AT+BAUD
 
 For example for multiwii, we need 115200 as the BT baud rate, we would
 enter AT+BAUD8.
 
 If successful you should be returned “OK” in the serial monitor.

You can change the baud rate of the HC-06 by using AT commands

<pre><code>#include &lt;SoftwareSerial.h&gt;
SoftwareSerial btSerial(2, 3); // RX, TX
/*
* Connect pin 2 Arduino to pin TX HC-06 
* Connect pin 3 Arduino to pin RX HC-06
*/ 
void setup() {
Serial.begin(9600);
Serial.println("Enter AT commands:");
btSerial.begin(9600);
}
void loop()
{
if (btSerial.available())
Serial.write(btSerial.read());
if (Serial.available())
btSerial.write(Serial.read());
}
</code></pre>

AT

AT+BAUD4==>9600

AT+BAUD8==>115200

I am doing a project in Arduino and want sensor data on my Android. For this purpose I am using HC-05 BT module and Bluetooth Terminal app on Android. But Bluetooth Terminal is receiving data at constant rate (1 sec, I think). And I want to receive data in 10 millisecs. How can I do this? 

Here is my code:

<pre><code>#include &lt;SoftwareSerial.h&gt;

int RX=0;
int TX=1;

SoftwareSerial Bluetooth(RX,TX);
int i=0;

void setup() {
 Bluetooth.begin(9600);
 Bluetooth.println("The controller has successfuly connected to the phone");
}

void loop() {
 Bluetooth.write(i);
 i++;
 delay(5); 
}
</code></pre>

How can I increase baud rate for bluetooth in Arduino?
