The illustration below shows the setup and hold times for the strapping pin before and after the CHIP_PU signal. so if someone decides to use the Arduino API then they want to know how to achieve what they need with the Arduino API, if it is possible. ulp 协处理器; 在启动DeepSleep后ESP32只剩RTC相关模块继续工作,其它所有模块全部关闭,所以我们需要根据需求手动处理一些事务,比如手动结束蓝牙、wifi等工作( esp_bluedroid_disable() esp_bt_controller_disable() esp_wifi_stop() ); 从DeepSleep唤醒后在Arduino core for the ESP32中. It’s the best choice for smart cities, smart farms, smart home, and IoT makers. 1 of esptool does not know about ESP32-PICO-D4, but it can still detect an ESP32 device, and the update went through normally.
