ESP32-S3 has only one 2.4 GHz ISM band RF module, which is shared by Bluetooth and Wi-Fi, so Bluetooth can’t receive or transmit data while Wi-Fi is receiving or transmitting data and vice versa. Under such circumstances, ESP32-S3 uses the time-division multiplexing method to receive and transmit packets.
