Re: 关于ESP32 WIFI功能功耗的问题
测试模组：ESP32-WROOM-32UE(4MB) 测试条件：电源能力3.3V@500mA 软件版本：ESP-IDF_V4.1.2 测试模式：ESP32模块作为站模式 问题表现：在进入deep sleep模式后，如果已经配置好WIFI的初始化，然后进入deep sleep，它的工作电流为1.7A左右，如果将WIFI相关代码注释后，进入deep sleep模式后工作电流为20-80uA。 在进入deep sleep前尝试调用了esp_wifi_stop()，但是结果依旧，问一下是什么原因导致这种问题，下面是我的WiFi初始化相关代码。 static void initialise_wifi(v...

Re: ESP32-C3 power consumption doesn't match to the datasheet
Have you tried esp_deep_sleep() and esp_deep_sleep_start().
When i call the first function, the current consumption is 10~20uA while the latter is 80~90uA.
So weird!

Re: ESP32-C3 power consumption doesn't match to the datasheet
Hi！
I am using a bare esp2-wroom-32ue module to measure the current consumption, i used the deep_sleep example.
I only use the rtc and ext1 to wake up the esp32, but the measured current is:80-90uA which does not match the datasheet.
I want to know what i have missed.
regards.

Re: ESP32 休眠时, IO口要怎么处理才能低功耗
使用的示例为example/system/deep_sleep，模组是esp32-wroom-32UE，只使用了RTC和ext1唤醒
我是直接用模组引出线来下载并测试，测试结果deep sleep情况下工作电流为80-90uA，不是手册给出的10uA，问一下可能是啥原因
