SmartConfig
SmartConfigTM 是由 TI 开发的配网技术，用于将新的 Wi-Fi 设备连接到 Wi-Fi 网络。它使用移动应用程序将无线网凭据从智能手机或平板电脑端广播给未配网的 Wi-Fi 设备。
这项技术的优势在于，设备无需直接获知 AP 的 SSID 或密码，而是通过智能手机获取。这对于没有用户界面的无头设备和系统而言十分重要。
如需通过其他方式为 ESP32-C2 设备配网，请参阅 配网 API。

Functions
-
const char *esp_smartconfig_get_version(void)
Get the version of SmartConfig.
- 返回
SmartConfig version const char.
-
esp_err_t esp_smartconfig_start(const smartconfig_start_config_t *config)
Start SmartConfig, config ESP device to connect AP. You need to broadcast information by phone APP. Device sniffer special packets from the air that containing SSID and password of target AP.
- Attention
1. This API can be called in station or softAP-station mode.
- Attention
2. Can not call esp_smartconfig_start twice before it finish, please call esp_smartconfig_stop first.
- 参数
config -- pointer to smartconfig start configure structure
- 返回
ESP_OK: succeed
others: fail
-
esp_err_t esp_smartconfig_stop(void)
Stop SmartConfig, free the buffer taken by esp_smartconfig_start.
- Attention
Whether connect to AP succeed or not, this API should be called to free memory taken by smartconfig_start.
- 返回
ESP_OK: succeed
others: fail
-
esp_err_t esp_esptouch_set_timeout(uint8_t time_s)
Set timeout of SmartConfig process.
- Attention
Timing starts from SC_STATUS_FIND_CHANNEL status. SmartConfig will restart if timeout.
- 参数
time_s -- range 15s~255s, offset:45s.
- 返回
ESP_OK: succeed
others: fail
-
esp_err_t esp_smartconfig_set_type(smartconfig_type_t type)
Set protocol type of SmartConfig.
- Attention
If users need to set the SmartConfig type, please set it before calling esp_smartconfig_start.
- 参数
type -- Choose from the smartconfig_type_t.
- 返回
ESP_OK: succeed
others: fail
-
esp_err_t esp_smartconfig_fast_mode(bool enable)
Set mode of SmartConfig. default normal mode.
- Attention
1. Please call it before API esp_smartconfig_start.
- Attention
2. Fast mode have corresponding APP(phone).
- Attention
3. Two mode is compatible.
- 参数
enable -- false-disable(default); true-enable;
- 返回
ESP_OK: succeed
others: fail
