esp32s3: Implement the Wi-Fi/BLE coexistence
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.

|

Wi-Fi supports the Modem-sleep mode which refers to the legacy power-saving mode in the IEEE 802.11 protocol.
|
||||
Modem-sleep mode works in station-only mode and the station must connect to the AP first. If the Modem-sleep
|
||||
mode is enabled, station will switch between active and sleep state periodically. In sleep state, RF, PHY and
|
||||
BB are turned off in order to reduce power consumption. Station can keep connection with AP in modem-sleep mode.
|
||||
|
||||
Modem-sleep mode includes minimum and maximum power-saving modes.
|
||||
|
||||
In minimum power-saving mode, station wakes
|
||||
up every DTIM to receive beacon. Broadcast data will not be lost because it is transmitted after DTIM.
|
||||
However, it cannot save much more power if DTIM is short for DTIM is determined by AP.
|
||||
|
||||
In maximum power-saving mode, station wakes up in every listen interval to receive beacon. This listen interval
|
||||
can be set to be longer than the AP DTIM period. Broadcast data may be lost because station may be in sleep
|
||||
state at DTIM time. If listen interval is longer, more power is saved, but broadcast data is more easy to lose.
|
||||
Listen interval can be configured by setting ESP32S3_WIFI_LISTEN_INTERVAL.
|
||||
|
||||
ESP32S3_POWER_SAVE_NONE disables Modem-sleep mode entirely. Disabling it increases power consumption, but
|
||||
minimizes the delay in receiving Wi-Fi data in real time. When Modem-sleep mode is enabled, the delay in
|
||||
receiving Wi-Fi data may be the same as the DTIM cycle (minimum power-saving mode) or the listening interval
|
||||
(maximum power-saving mode). Setting ESP32S3_POWER_SAVE_NONE is suitable when high throughput is required.
