EASY plug Bluetooth 2.0 Module

Introduction

Keyestudio Bluetooth 2.0 module can easily achieve serial wireless data transmission. The operating frequency is among the most popular 2.4GHz ISM frequency band (i.e. Industrial, scientific and medical).
It adopts Bluetooth 2.1+EDR standard. In Bluetooth 2.1, signal transmit time of different devices stands at a 0.5 seconds interval, so that the workload of Bluetooth chip can be reduced substantially and more sleeping time can be saved for Bluetooth.
It has build-in on-board antenna which provides high quality signals. 
Note: this module should be used together with EASY plug control board.

Upload the Code

Copy and paste below code to Arduino IDE and upload.
Firstly should upload the code to control board, then connect the Bluetooth module. Otherwise, it will fail to upload the program. 

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");
}}


What You Should See

Done uploading the test code, powered on, power indicator is turned on, and LED on Bluetooth module is blinking.
