!! This project is fork by URL: https://github.com/android/connectivity-samples. This BluetoothServer should be run on Android devices and connect the client which is created by python(no provied code), to establish a two-way transport data over Bluetooth between the devices. But we only need to transport client data to the server.

Select "Made discoverable" in overflow menu on one device and click on the Bluetooth icon on the other one, to find the device and establish the connection. It will display the vital signs extracted from the client.

The sample demonstrates the following, using the [Bluetooth API]:

1. [Setting up] Bluetooth
2. [Querying] the local Bluetooth adapter for paired Bluetooth devices. No need to connect
3. Open discoverable button and wait for the client for 2 min
4. [Establishing RFCOMM] channels/sockets co
5. [Connecting] to a remote device
6. [Transfering] data over Bluetooth

sudo pat-get update sudo apt-get install libbluetooth-dev sudo pip install pybluez

Start RFCOMM service sudo sdptool add SP sudo rfcomm watch hci0

You can follow other operation of this URL: https://github.com/pybluez/pybluez/. It will provide the example of rfcomm-client. You can use "uuid" or "address" to connect your server. TO build your rfcomm-client!.
