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. 

Parameters

  • Bluetooth protocol: Bluetooth 2.1+ EDR standard
  • USB protocol: USB v1.1/2.0
  • Operating frequency: 2.4GHz ISM frequency band
  • Modulation mode:  GFSK (Gauss Frequency Shift Keying)
  • Transmit power: ≤ 4dBm, class 2
  • Sensitivity: ≤-84dBm at 0.1% Bit Error Rate
  • Transfer rate: Asynchronous: 2.1Mbps(Max)/160k         Synchronous: 1Mbps/1Mbps
  • Safety  feature: Authentication and encryption
  • Supported configuration: Bluetooth serial port
  • Supply Voltage: 5V DC /50mA
  • Operating temperature: -20℃ to +55℃

 

Sample code:
 
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("Hello keyes!");
}}
