Library Description

Library provides functions and macros for complete control over device. Library has one buffer that collects data with zigbee_process function. You can clear it and write it with library functions, you can also check if there is new data in buffer with zigbee_resp. There is generic function for sending one string of data, and one additional function for concating two string so you can use predefined AT commands from library.

Key functions:

• void zigbee_send_cmd ( uint8_t *cmd_buf ) - Sends string to device
• void zigbee_process ( uint8_t process_b ) - Collects data to library buffer
• uint8_t zigbee_resp ( void ) - Checks if there is new data in library buffer

Examples description

The application is composed of three sections :

• System Initialization - Initialization of UART module and additional pins
• Application Initialization - Initialization of driver, UART ISR and then configures device. Depending on previous selected device mode it creates new PAN network or joins to one.
• Application Task - * Host mode: Broadcasts message 'MikroE' every 3 seconds. * User mode: Cheks if something is received.

void application_task ( )
{
    if ( DEV_HOST == dev_mode )
    {
        //Broadcasts message 'MikroE' over it's PAN network
        zigbee_send_at( ZIGBEE_AT_BCAST, &AT_BCAST_MSG[ 0 ] );
        resp_wait(  );
        Delay_ms( 3000 );
    }
    else if ( DEV_USER == dev_mode )
    {
        //Checks if there is something received
        resp_wait(  );
    }
}

Additional Functions :

• void logger_function ( uint8_t *demo_txt, uint8_t write_macro ) - Wrapper function
• void resp_wait ( ) - Function for waiting for complete response

Other mikroE Libraries used in the example:

• UART
• C_String

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.
