Library Description

Library carries generic command parser adopted for AT command based modules. Generic parser.

Key functions:

• wifible_cmdSingle - Sends provided command to the module.
• wifible_setHandler - Handler assignation to the provied command.
• wifible_modulePower - Turn on module.

Examples description

The application is composed of the three sections :

• System Initialization - Initializes all necessary GPIO pins, UART used for the communcation with WiFi-BLE module and UART used for infromation logging.
• Application Initialization - Initializes driver, power on module and sends few command for the default module configuration.
• Application Task - Waits for valid user input and executes functions based on set of valid commands.

Commands : '+' - Next command 's' - Start command 'e' - change example (WiFi example / BLE example)

Additional Functions :

• void _packageBeaconData( ) - Package iBeacon data
• void _WiFi_TCPServer( ) - WiFi example / command list
• void _BLE_iBeacon( ) - BLE example / command list

Timer initialization and default handler.

        {
            _WiFi_TCPServer(command_cnt);
        }
        if(fExample == _WIFIBLE_BLE_EXAMPLE)
        {
            _BLE_iBeacon(command_cnt);
        }
    }
}

Alongside with the demo application timer initialization functions are provided. Note that timer is configured acording to default develoment system and MCUs, changing the system or MCU may require update of timer init and timer ISR functions.

Other mikroE Libraries used in the example:

• String
• Conversion

Additional notes and informations

Depending on the development board you are using, you may need USB UART click, USB UART 2 click or RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.
