Control Your Arduino BLE Device Using Smartphone
Here you can learn how to control a device using BLE module
Arduino pin 9 ----Bluefruit RX
Arduino pin 10---Bluefruit TX
Arduino pin 11---Bluefruit CTS
Arduino pin 12---Bluefruit Mode pin
Arduino GND---Bluefruit GND
Arduino Vcc---Bluefruit Vcc
Arduino pin 3---led
Arduino pin 6---Buzzer
This example demonstrates how a device can be controlled using your smartphone.Here i am controlling An LED and buzzer using android App.This device will read incoming data from any other BLE device(which is working in central mode)and do actions.
Incoming data Actions
character 1(ASCII49) ---------- LED ON
character 2(ASCII50) ---------- LED OFF
character 3(ASCII51) ---------- will reply "Thank you for reading wiring it my way"
character 4(ASCII52) ---------- BUZZER ON
character 5(ASCII53) ---------- BUZZER OFF
You can use your own BLE app.Here I am Using bluefruit LE app from adafruit. in that after pairing your device to your phone open UART mode in your app and send different characters like 1,2,3,4,5 and test your BLE.
As you know this is only the basic intro off BLE.Now try your own devices like BLE controlled toys,sensor data apps etc.please commend your BLE experiences.
