I am using a Bluetooth device to connect with the android Phone manually there is no problem. But My Question is how can I connect automatically when I starts my Activity or Application .
I am taking the reference of Bluetooth chat in Sample API to connect. http://developer.android.com/resources/samples/BluetoothChat/index.html
Please Suggest me.
Yes you can achieve this using Bluetooth API. First of all you need to get that Device’s Address. Now in activity you need to make it hardcode(static) for connection. you can write code in OnCreate() Method of Activity for Automatic Connection.
