Library Description 

BroadR-Reach click library contains basic functions for controlling the click board, but also the advanced functions, which abstract basic operations to a simple send or receive functions. 

Key functions:

uint8_t broadr_socketOpen(uint8_t socket, uint8_t mode, uint16_t settings)- Opens a socket in the selected mode, enabling its operation

uint8_t broadr_sendData(uint8_t socket, uint8_t * pSendData, uint16_t bytesCount)- Ends data from the selected socket

uint8_t broadr_receiveData(uint8_t socket, uint8_t mode, uint8_t * pReceiveData, uint8_t * headerInformation)- Reads received data from the selected socket

Examples Description

The application is composed of three sections :

• System Initialization - Initializes pin, SPI peripheral, and logger functions.
• Application Initialization - Initializes the click driver, sets the required network parameters (Addresses), opens socket 0 in UDP mode, and sets the destination address and port for that socket.
• Application Task - Sends data contained in the sendData array and checks if any data has been received. If so, the received data is printed on UART. Contents of the sendData array are automatically changed in each iteration, so that each sent packet is different from the previous.

     * Sends sendData

    broadr_sendData(_BROADR_SOCKET0, &sendData, 18);

    /*
     * Checks if data is received, and writes received data if so.
     */
    if (broadr_getReceivedSize(_BROADR_SOCKET0))
    {
        mikrobus_logWrite("Received data:", _LOG_LINE);
        broadr_receiveData(_BROADR_SOCKET0, _BROADR_MODE_UDP, &receivedData, &receiveHeader);
        mikrobus_logWrite(receivedData, _LOG_LINE);
    }
    else
    {
        mikrobus_logWrite("No data received.", _LOG_LINE);
    }

    /*
     * Increments packet number in send data text, resets after 99.
     */
    sendData[16] = sendData[16] + 1;
    if (sendData[16] > '9')
    {
        sendData[16] = '0';
        sendData[15] = sendData[15] + 1;
    }
    if (sendData[15] > '9')
    {
        sendData[15] = '0';
    }

    Delay_ms(1000);

• UART

Additional notes and information

Depending on the development board you are using, you may need USB UART click, USB UART 2 clickor 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.
