Wireless SUN Click

Wireless SUN Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

Example Description

This example demonstrates the use of Wireless SUN Click board by showing the communication between the two Click boards configured as BORDER and ROUTER.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.WirelessSUN

Example Key Functions

• wirelesssun_cfg_setup Config Object Initialization function.

void wirelesssun_cfg_setup ( wirelesssun_cfg_t *cfg );

• wirelesssun_init Initialization function.

err_t wirelesssun_init ( wirelesssun_t *ctx, wirelesssun_cfg_t *cfg );

• wirelesssun_send_cmd This function sends a specified command to the Click module.

void wirelesssun_send_cmd ( wirelesssun_t *ctx, char *cmd );

• wirelesssun_send_cmd_with_parameter This function sends a specified command to the Click module with desired parameters appended to.

void wirelesssun_send_cmd_with_parameter ( wirelesssun_t *ctx, char *cmd, char *param_buf );

• wirelesssun_generic_read This function reads a desired number of data bytes by using UART serial interface.

err_t wirelesssun_generic_read ( wirelesssun_t *ctx, char *data_out, uint16_t len );

Application Init

Initializes the driver and configures the Click board by performing a hardware reset and a clear parameters feature, and setting the device network name, device role to BORDER or ROUTER depending on the application mode. In the end, it saves settings and reboots device.

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    wirelesssun_cfg_t wirelesssun_cfg;  /**< Click config object. */

    /** 
     * Logger initialization.
     * Default baud rate: 115200
     * Default log level: LOG_LEVEL_DEBUG
     * @note If USB_UART_RX and USB_UART_TX 
     * are defined as HAL_PIN_NC, you will 
     * need to define them manually for log to work.

Application Task

Depending on the selected application mode, it reads all the received data and parses the received TCP/UDP messages (BORDER mode) or waits for the connection, reads the parent global address, and then starts sending a desired TCP/UDP messages to the parent every 3 seconds (ROUTER mode).

Note

By default, the BORDER application mode is selected. comment out the DEMO_APP_BORDER macro definition in order to switch the application mode to ROUTER.

Application Output

This Click board can be interfaced and monitored in two ways:

• Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
• UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
