Android BluetoothChat example link with HC-05 Bluetooth

This example show to import and modify Android BluetoothChat example, to link with low-cost Bluetooth HC-05.

First test HC-05 Bluetooth Module
AT Command mode of HC-05

We need a FTDI USB-to-Serial adapter to connect PC/USB and HC-05 Bluetooth, and use Arduino IDE's Serial Monitor as terminal, to talk with Android running modified BluetoothChat example.

This video show how to import BluetoothChat example in Android Studio, and edit to change MY_UUID_SECURE to UUID.fromString("00001101-0000-1000-8000-00805F9B34FB").

~ reference you are connecting to a Bluetooth serial board then try using the well-known SPP UUID 00001101-0000-1000-8000-00805F9B34FB.

This video show how it run on Android device, and talk to PC running Arduino IDE's Serial Monitor, via FTDI + HC-05.

In my on-hand HC-05 sample, it set as slave role and 9600, 0, 0, PIN="1234" by default, I have not change any setting.

Cross post with Arduino-er.
