Program a Laird BL600 Bluetooth 4.0 Module to work as a RSSI activated switch controlled by an existing Android app. The electronic circuit of the device has already been designed. The functions of the BL600 will basically be to output a signal for activating a transistor when the Android device is near and also when the Android app signals it to activate.
The app is already functional and currently works with Tinyos TOSR02-BluetoothBee Wireless module, so communication protocols can be the same and don't have to be changed unless necessary.
If you are interested, but don't agree with the amount $$, please make an offer.
