4.10.11 Do ESP8266/ESP32/ESP32-S2/S3/C2/C3 support web/SoftAP provisioning?
Yes.
• For ESP8266, please refer to example ESP8266 softap_prov.
• For ESP32/ESP32-S2/S3/C2/C3, please refer to example ESP32/ESP32-S2/S3/C2/C3
wi󰝘_prov_mgr.
4.10.12 [Connect] How do ESP8266 and ESP32 hide SSID in SoftAP mode?
To hide ESP8266 or ESP32 as SSID in SoftAP mode, you can use the following methods:
• Use the esp_wi󰝘_set_con󰝘g() function to con󰝘gure the SSID and password in SoftAP mode and
whether to hiding them. For example, the following code sets the SSID to “MySoftAP”, the
password to “MyPassword”, and set .ssid_hidden = 1 to hide the SSID:
wifi_config_t config = {
.ap = {
.ssid = "MySoftAP",
.ssid_len = strlen("MySoftAP"),
.password = "MyPassword",
.max_connection = 4,
.authmode = WIFI_AUTH_WPA_WPA2_PSK
.ssid_hidden = 1
},
};
esp_wifi_set_config(WIFI_IF_AP, &config);
Then use esp_wi󰝘_start() function to starts Wi-Fi.
4.10.13 Does the buer parameter in esp_wi_802.11_tx interface include FCS?
No, the FCS frame is generated automatically by hardware.
4.10.14 What is the supported Wi-Fi frequency band and power meter for ESP-
WROOM-32D?
The Wi-Fi frequency band is 2412 ~ 2484 MHz, and the available channels and corresponding oper-
ating frequencies can be con󰝘gured in software. There are default values in power meter, and it can
also be con󰝘gured by software. For detailed guidance, please refer to ESP32 Phy Init Bin Parameter
Con󰝘guration Guide.
4.10.15 What is the maximum value of ESP32 Wi-Fi RF power？
The output RF power of ESP32 can be set to 20 dBm at maximum. Please note that the maximum
output power may vary in di󰝗erent countires and regions. Please ensure that you comply with local
rules and regulations when using ESP32. In addition, high power output also in󰝙uence battery life and
Wi-Fi signal stability. As a result, you should con󰝘rm the output power depending on applications and
requirements.
