Bluetooth App for Android OS

I need an Android based application developed with a single function. The function of the app is to autopair with a specific Bluetooth receiver. That's it. I have created a keychain with a built in bluetooth receiver. I simply need an application that cna find this specific receiver and auto-pair with it. I would only like to receive bids from experience APP developers who are familiar with Bluetooth technology. More details about the application will be given to the chosen developer.
