Description:
A: Modem-sleep mode is used in scenarios that require the CPU to work all the time, such as PWM or I2S. When Wi-Fi
connecting, if there is no data transmission, according to the 802.11 standard (such as U-APSD), turn off the Wi-Fi
Modem circuit to save power. For example, in DTIM3, keep the sleep interval of 300 ms, and wake up 3 ms each time to
