Depending on the actual situation, it is possible to configure the module to operate in modes such as Modem-sleep, light-sleep, or deep-sleep within a certain working range, which is beneficial for reducing power consumption.

1. Is the hardware functioning correctly and connected properly? 2. Is the UART port of the Wi-Fi module connected consistently? 3. Have you included carriage return and newline characters when sending commands from the serial assistant?

2.4GHz: Longer transmission distance, lower speed compared to 5GHz, but more susceptible to interference.

5GHz: Shorter transmission distance, faster speed compared to 2.4GHz, but less susceptible to interference and more stable.

Wi-Fi 4: Supports the 2.4GHz and 5GHz frequency bands.

Wi-Fi 5: Operates in the 5GHz frequency band.

Wi-Fi 6: Operates in the 2.4GHz and 5.8GHz frequency ban

Default is 10.

Yes, it's possible to use AT commands to read information such as SSID, MAC address, RSSI, etc., of the scanned nearby access points (APs). After retrieving this information, it can be uploaded to a server for further processing and localization calculations.

Yes, in PICO VR use cases, ESP8266's I2C interface is used, and similarly, ESP32-C3 can also use the I2C interface to achieve the same functionality.
