当ESP32 作为 STA 和 AP进行通信时,接收完一次数据后需要等待一段时间再关闭 RF,这个时间称为 Minimum active time,默认值为50 ms, 在保证每次数据吞吐量的基础上,可以适当减少这个等待时间来降低功耗。 而当ESP32 处于power save 模式下时,需要周期性的给 AP 发送一个 keep alive 包来告诉 AP 自己还保持着...
测试esp-idf v3.3 中的例子power_save。 发现ESP32有时可以进入省电模式,有时不可以进入省电模式。感觉省电模式很不稳定,进入省电模式需要什么条件?是否受路由器的影响? 如果进入WIFI_PS_MIN_MODEM,测的电流约为10mA;如果进入WIFI_PS_MAX_MODEM,测的电流约为4mA。ESP32保持空连接,最省电可以达到多少电流?

I need to run power save example on ESP32-C6 board in the light sleep mode. Can someone help me out with the memory configuration, clock configuration and peripheral configuration details. In the datasheet, for the light sleep mode there are two configurations as follows: esp_sleep_config....
【问题】我在尝试idf中的power_save例程,我仅仅在menuconfig中修改了SSID和password以及WiFi listen interval设置为1,烧录到ESP32S2-MINI-1中运行一段时间后会出现如下错误,并且重启数次。同样的代码,放到ESP32-wroom上就没有问题。 并且我尝试过在ESP32S2上取消Support for power management选项中就不会出现此类错误...
I've managed so far to program an SSE client with lvgl ui, which works fine, but draws ca. 780 mA of current from a 5V source. I'd like to realize a power save mode for this, meaning the screen is dark, all peripherals are powered down _except_ the touch function of the screen...
