ESP8266移植阿里LinkSDK

https://help.aliyun.com/zh/iot/developer-reference/port-the-sdk-to-esp8266

更正内容

• 用户需要下载附件posix_port.c（适配了esp8266），用它将LinkSDK中portfiles/aiot_port/freertos_port.c替换掉。

1. 移植demo程序

   我们通过修改 examples/wifi/getting_started/station/下的example来完成mqtt上云的演示。

   原生的例程主要演示使用wifi station模式接入特定的wifi热点， 用户可下载附件源文件覆盖原有的 station_example_main.c

   修改Kconfig.projbuild

menu "Example Configuration"

    config ESP_WIFI_SSID
        string "WiFi SSID"
        default "myssid"
        help
            SSID (network name) for the example to connect to.

    config ESP_WIFI_PASSWORD
        string "WiFi Password"
        default "mypassword"
        help
            WiFi password (WPA or WPA2) for the example to use.

    config MAX_STA_CONN
        int "Maximum retry"
        default 5
        help
            Set the Maximum retry to avoid station reconnecting to the AP unlimited when the AP is really inexistent.
          
    config ESP_WIFI_MODE_AP
        int "STA 0, AP 1"
        default 0
        help
            Set the Maximum retry to avoid station reconnecting to the AP unlimited when the AP is really inexistent.
endmenu

printf("xTaskCreate demo_mqtt_process_task failed: %ld\n", ret);改为 printf("xTaskCreate demo_mqtt_process_task failed: %d\n", ret);

E:\ESP8266\ESP8266_RTOS_SDK\components\LinkSDK\components\dynreg\dynreg_private.h中修改宏定义

#defineDYNREG_PATH "/auth/register/device"

改为

#defineDYNREG_PATH "/admin-api/iot/device-info/auth/register/device"

使用mqtts tls连接平台

配置主任务栈大小

# Component config → ESP8266-specific → 
#   Main task stack size (4096)

配置

    memset(&cred, 0, sizeof(aiot_sysdep_network_cred_t));
    cred.option = AIOT_SYSDEP_NETWORK_CRED_SVRCERT_CA;  /* 使用RSA证书校验MQTT服务端 */
    cred.max_tls_fragment = 16384; /* 最大的分片长度为16K, 其它可选值还有4K, 2K, 1K, 0.5K */
    cred.sni_enabled = 1;                               /* TLS建连时, 支持Server Name Indicator */
    cred.x509_server_cert = ali_ca_cert;                 /* 用来验证MQTT服务端的RSA根证书 */
    cred.x509_server_cert_len = strlen(ali_ca_cert);     /* 用来验证MQTT服务端的RSA根证书长度 */

配置ali_ca_cert
