How do I transfer data from Arduino to app?

How do I transfer data from Arduino to app?

If both devices are coupled, go to the app, pick the HC-05/HC-06 and click the red connect-button. “Arduino Bluetooth Data” should establish a serial connection. In the Arduino-Code you determine on your own which values you want to send to the Android-Device.

How do I connect my Arduino to my Android?

You Will Need

  1. Android Phone – The phone used needs to support USB Host Mode (i.e OTG Support).
  2. Arduino – Any version will do, but we used an Uno R3.
  3. Arduino USB Cable.
  4. USB OTG Cable – This component connects the USB cable of your Arduino to the micro-USB port of your Android phone.

How to send and receive data with Android and Arduino?

I am trying to write an Android application that can send and receive serial data to and from an Arduino board that is connected by an On-The-Go (OTG) adapter. I am using the usb-serial-for-android library. I am setting the Arduino up so that if it receives the string “T” then it will send the string “T” back.

How to pair your Android phone with Arduino?

Pair your phone with HC-05. for doing this go to Settings->Bluetooth->Scan device->select HC-05 and pair it. Pass code to pair is ‘1234’. 3. Now, open the app and connect the HC-05 module.

What happens when you send a code to Arduino?

If you send ‘A’ it will make to LED ON and if you send ‘B’ it will make the LED OFF. The Arduino code also sends the current state of LED also.

Why does my Arduino flash differently when I start the app?

When I start the application, the bluetooth module of the Arduino flashes differently. (I guess it’s because my app connectswith the board). Inside the Log Cat, it can be seen that the connection has been made correctly. . . What could be missing here to print the data received from the Arduino?
