Introduction

Bluetooth Shield integrates a Serial Bluetooth module. It can be totally compatible to Arduino/ Catduino for unvarnished transmission. Digital 0 and 1 is Hardware Serial Port, and choose two pins from D0 to D7 in Arduino as the software port, the external f analog IOs can be used to connect with other devices.

Technical Data

Operate frequent: 433MHz

Operate voltage: 1.8 to 3.6V

Transmission rate: 300Kbps

Max emission power: 20dBm

Max emission current: 120mA

Receive sensitivity: -120dBm @ 1.2Kb/s

Features

Low consumption

More professional ISM band

Usage

Connect wire jumper to BLE shield like below:

Plug BLE shield to Arduino/Catduino

Upload following program to Arduino/Catduino

[code]

// the setup function runs once when you press reset or power the board

void setup() {

  // initialize digital pin LED_BUILTIN as an output.

  pinMode(LED_BUILTIN, OUTPUT);

  Serial.begin(115200);

}

// the loop function runs over and over again forever

void loop() {

  digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)

  delay(1000);                       // wait for a second

  digitalWrite(LED_BUILTIN, LOW);    // turn the LED off by making the voltage LOW

  delay(1000);                       // wait for a second

}

 [/code]

Open serial monitor, set the baud rate at 115200, send AT, if you got respond of “OK”, BLE shield work.
