Blue Arduino

Easy lightweight app for Bluetooth communication between e.g. an Android phone and Arduino(using a Bluetooth module).

Functionality:
- List all Bluetooth devices available
- Send a string to the device
- Listen and display response from device
- Clock widget for setting time for e.g. an Arduino based clock
- Send an array of bytes to device (hex format)

# Clock widget
Will take hour and minute as input and send it as a string on the format: #HHMMSS

# Send Byte array
Accepts bytes on hexadecimal format. One byte corresponds to two digits in hex. For example. If you want to send 8 bytes that all have value 1 input the following: 0x0101010101010101
