Description

The Bluetooth Shield integrates a Serial Bluetooth module. It can be easily used with Arduino /Crowduino for transparent wireless serial communication. You can choose two pins from Arduino D0 to D7 as Software Serial Ports to communicate with Bluetooth Shield (D0 and D1 is Hardware Serial Port). It also expand five analog IOs that you can use it to connect other devices.

Model: MCS01108S

Usage

Communicating between two Bluetooth Shield

Upload1.jpg
This demo will show you how to communicate between two Arduino/Crowduino through Bluetooth Shield.For the special applications, you may need to write the code by yourself.

  • Download the Arduino Library for the shield, and unzip it into the path of Arduino Libraries. This library includes two sketch, one for Master and the other for Slave. Make sure Software Serial Library is included as well.

  • Upload the sketch Master.ino and Slave.ino to two separate Arduino/Crowduino.

  • Open two Serial Terminals on your PC, with the setting of 38400, 8, 1, N. Open the two Com Port of Arduino/Crowduino.

  • Plug the Bluetooth Shields to the Master board and the Slave Board, and reset the two boards.

Then you will see the red and green LED on the board are flashing in interval indicting they are inquiring for each other. After a while only the green led is flashing one time per second indicating that they are connected. There's also some information printed on the two terminal as following.

  • The connection is successful now, and you can type any character on the Serial Terminal and send to each .

Connecting Bluetooth Shield to Android Phone

This demo will show you how to connect Bluetooth Shield to Android Phone. Here we test on HTC Legend with Android 2.2.For the special applications, you may need to write the code by yourself.


  • Download the Arduino Library for the shield, and unzip it into the path of Arduino Libraries. This library includes two sketch, one for Master and the other for Salve. Make sure Serial Library is included as well.

  • Plug the Bluetooth Shield onto the Arduino/Crowduino, and upload the Slave.ino to the board.Open the Serial Terminal with setting of 9600, 8, 1, N.

  • Download an Serial Terminal for Android to the phone. Install the apk(Bluetooth SPP).
  • Enable the bluetooth function and scan for devices. You will find the CrowBTSlave device.
  • Select and pair with the "CrowBTSlave", input the PIN code 0000, choose OK.
