<br>
==Introduction==
Keyestudio Bluetooth XBee Bluetooth wireless module HC-05 adopts XBEE design. <br>
It has features of compact size, compatible with XBEE shield, and suitable for various 3.3V MCU systems. <br>
The module can use AT command to set baud rate and master/slave mode, user info etc. <br>
The default settings are baud rate 38400, paring password 1234. <br>
It comes with efficient on-board antenna. The exposed antenna ensures better signal quality and longer transmitting distance. Transparent serial port can be used to pair up with various Bluetooth adapters, Bluetooth phones. <br>
The humanized design offers convenience for secondary development.<br>
After testing, the module is known to be suitable in using with all Bluetooth adapters on the market (PC and phones with Bluetooth).<br>

<br>
==Specification==
* Supply voltage: 3.3V (voltage above 3.3V is forbidden. It will damage the module)
* Bluetooth paring user name: HC-05
* Bluetooth paring password: 1234
* Default baud rate: 38400
* Modified baud rate takes effect after module reboot

<br>
== Connection ==
Stack it onto the board

<br>
== Sample Code ==
<pre>
int val; 
int ledpin=13; 
void setup() 
{ 
Serial.begin(9600);
 pinMode(ledpin,OUTPUT); 
} void loop()
{ val=Serial.read(); 
if(val=='a')
 { 
digitalWrite(ledpin,HIGH); 
delay(250); 
digitalWrite(ledpin,LOW); 
delay(250);
 Serial.println("keyestudio");
}
}
</pre>

<br>
== Test Result ==
Connect the shield to APC ports; enter cell phone “settings”; pair up the Bluetooth; device name is HC-05; pairing PIN No. is 1234. After device is paired, open APP “BTClient”; click search for device, pair up the Bluetooth. <br>
After successful connection, enter “a” in BTClient and click send, the BTClient APP page will display keyestudio. And Pin13 LED will blink once.<br>
