Here is the serial terminal.

Here is a clip of the lwip configuration options.  I wouldn’t recommend changing anything unless you are sure you know what you are doing.

The makefile controls all of the libraries.  To enable these libraries you need to add the following “components” to the list if they aren’t already there. (Note that all of this information is in the Quick Start section of the library’s documentation).

COMPONENTS= FREERTOS LWIP MBEDTLS

And you need to tell the system about the configuration.

DEFINES+= MBEDTLS_USER_CONFIG_FILE='"mbedtls_user_config.h"' 
DEFINES+=CYBSP_WIFI_CAPABLE
DEFINES+=CY_RTOS_AWARE

Just like the other lessons you will need to create a public header file for the cloud task.

Inside of that file there will be only one function prototype for the task.

#pragma once

void cloud_task(void *param);

At the top of the file we will have some includes.  And I will define some macros that tell WiFi which AP to attach to. When you do this on your own, you will need to update those to match your WiFi AP SSID and password. The task itself is really simple for now, just connect to WiFi and then do nothing.

#include <stdio.h>

#include "FreeRTOS.h"
#include "task.h"

#include "cy_wcm.h"

#include "cloud_task.h"

#define CLOUD_WIFI_AP        "ew2021"
#define CLOUD_WIFI_PW        "ew2021ap"
#define CLOUD_WIFI_SECURITY  CY_WCM_SECURITY_WPA2_MIXED_PSK
#define CLOUD_WIFI_BAND      CY_WCM_WIFI_BAND_ANY

static void cloud_connectWifi();

void cloud_task(void* param)
{
    (void)param;

    cloud_connectWifi();

    while(1)
    {
        vTaskDelay(1);

    }
}

The connect to WiFi function will

1. Setup the Access Point information
2. Initialize the wireless connection manager
3. Then go into a loop that will attempt to connect until there is success.
4. Once a connection is made, it will print out the IP information.

static void cloud_connectWifi()
{
    cy_rslt_t result;

    cy_wcm_connect_params_t connect_param = {
        .ap_credentials.SSID = CLOUD_WIFI_AP,
        .ap_credentials.password = CLOUD_WIFI_PW,
        .ap_credentials.security = CLOUD_WIFI_SECURITY,
        .BSSID = {0},
        .band = CLOUD_WIFI_BAND,
    };
    cy_wcm_config_t config = {.interface = CY_WCM_INTERFACE_TYPE_STA}; // We are a station (not a Access Point)

    cy_wcm_init(&config); // Initialize the connection manager

    printf("\nWi-Fi Connection Manager initialized.\n");

    do
    {
        cy_wcm_ip_address_t ip_address;

        printf("Connecting to Wi-Fi AP '%s'\n", connect_param.ap_credentials.SSID);
        result = cy_wcm_connect_ap(&connect_param, &ip_address);

        if (result == CY_RSLT_SUCCESS)
        {
            printf("Successfully connected to Wi-Fi network '%s'.\n",
                    connect_param.ap_credentials.SSID);

            // Print IP Address
            if (ip_address.version == CY_WCM_IP_VER_V4)
            {
                printf("IPv4 Address Assigned: %d.%d.%d.%d\n", (uint8_t)ip_address.ip.v4,
                        (uint8_t)(ip_address.ip.v4 >> 8), (uint8_t)(ip_address.ip.v4 >> 16),
                        (uint8_t)(ip_address.ip.v4 >> 24));
            }
            else if (ip_address.version == CY_WCM_IP_VER_V6)
            {
                printf("IPv6 Address Assigned: %0X:%0X:%0X:%0X\n", (unsigned int)ip_address.ip.v6[0],
                        (unsigned int)ip_address.ip.v6[1], (unsigned int)ip_address.ip.v6[2],
                        (unsigned int)ip_address.ip.v6[3]);
            }
            break; /* Exit the for loop once the connection has been made */
        }
        else
        {
            printf("WiFi Connect Failed Retrying\n");
            vTaskDelay(2000); // wait 2 seconds and try again;
        }

    } while (result != CY_RSLT_SUCCESS);
}

In main.c you need to include the cloud task

#include "cloud_task.h"

Then start the cloud task.

xTaskCreate(cloud_task,    "Cloud"     ,configMINIMAL_STACK_SIZE*8  , NULL, 2, 0);
