Library Description

The library covers all the necessary functions to control Bluetooth Click board.
A library performs the communication with the device via UART interface with the RN-41 Bluetooth module.

Key functions:

• void bluetooth_writeByte(uint8_t input) - Write Single Byte.
• void bluetooth_uartWrite( uint8_t *txData ) - UART write function.
• BLUETOOTH_STATUS_T bluetooth_setDeviceName( uint8_t *name ) - Set the device name function.

Examples description

The application is composed of the three sections :

• System Initialization - Initializes UART structures sets RST pin as output and initialize variables.
• Application Initialization - Initialization driver enables - UART, enable interrupts routine, enter command mode, set device name, set extended status string, set operating mode, set auth, and set security pin code also write log.
• Application Task - This is an example which demonstrates the use of Bluetooth click board.

void applicationTask()
{
    cnt = 0;

    memset( txtBuffer, 0, 16 );
    EnableInterrupts();

    while ( !dataReady );

    Disableinterrupts();
    dataReady = 0;

    cnt = 0;
}

Additional Functions :

• char bluetooth_getResponse() - Get response from device function.

Other mikroE Libraries used in the example:

• UART
• Conversions

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.
