Generic Bluetooth Commands

This application allows you to define your own commands and send them via bluetooth to a paired device. It is up to you how you interpret these commands on the remote device, which could be an Arduino board, phone, PC, or any other device with Bluetooth module.

Commands could be defined in a string format or as an array of bytes (in hexadecimal format) with some additional options, such as including new line at the end of the string or selecting endian mode (ordering of bytes during transmission). Application can also listen to incoming transmisions and display incomming messages in various forms - user can choose between string, hexadecimal or decimal format.

All settings and user defined commands are saved / loaded each time application is closed / opened.

Application is simple and intuitive, however, here is a short user guide:

*Connecting to a device*
To connect to a device, it must be first paired with your phone. Then simply click Menu -> Connect and select a device.

*Creating commands*
To create a new command, click on the "empty item" in the list of commands. On the following screen choose between hexadecimal or string format - fill in the associated fields:
Command name - for user to identify specific command. If the field is left empty, default name is used

Value 0x(hexadecimal) - hexadecimal value (array of bytes) that represent command. Only valid hexadecimal number is accepted (characters 0-9 and A-F, not case-sensitive). Prefix "0x" is already included.

Least significant byte first - check this checkbox to send least significant byte of a command first. Otherwise the most significant byte will be send first.

String - String representing text form of your command

Include new line character at the end of the string - If checked, new line character ("n", 0x0A) will be appended at the end of the string

*Sending commands*
Commands are displayed in a list. You can send it to a connected device by clicking on respective item. Use long click to remove item from the list.
