Would the following be possible?
Let\'s say I have a scale with Bluetooth capabilities, when I turn it on, it sends the weight via BT.
Is it technically possible
Yes, we can connect Bluetooth devices with iOS application through Core bluetooth framework. This framework is supported on the iPhone 4s, iPhone5,iPhone 5S ,iPad3. We can use BLE 4.0 for the communication between scale and iOS application. Here, iOS application become the client and scale become the peripheral. You Can set as well as get data from the weighing scale.
