Light_BLE

An enhanced android app to communicate with Bluetooth LE peripheral.

This app maybe useful in Bluetooth Low Energy peripheral equipment development. It is based on an example in Android's SDK source code smaple which located in sdk/samples/android-19/connectivity/BluetoothLeGatt/ , but that exmaple is so sucks(yeah, Light BLE is still sucks, but much better than that sample).

Following is what I emproved based on that sample.

1. Change the LocalService and Activity communication mechanism from broadcast intent into callback hooks.
2. Add RSSI signal detect.
3. Add write characteristic dialog(still need improve).

Why I make above emprovment?

1. Broadcast Intents was not dependable, I guess that's the reason that I missed a lot of messages. So I studied the communicaiton between Service and Acitivity, and decided to use callback hooks to send feedback or messages to the forground Activity.

2. Since, I wanna develop an Loss-Resistant device, the most silly implementation is to detect the RSSI signal strength, and write a characteristic value back to BLE devices back to inform whether it is losed or not. So I add an RSSI signal detection function into that APP.

3. Some time, we just need to write an characteristic value into the BLE database to operating the peripheral device. That's an practical function in BLE device development. There are an ios APP named LightBlue, I refered its function to add above functions. Actually, that's another reason why I develop this app, I can't found any available APP in android platform.
