在开启和未开启wifi模式下进入sleep模式的功耗差异:
1、未使能wifi功能,休眠功耗大致在5微安左右。
2、先使能wifi功能,后关闭wifi功能进入休眠模式,功耗增加至1.4毫安左右:
esp_wifi_stop();
esp_deep_sleep_start();
这种现象是否正常,是什么原因导致的。
谢谢!

Re: 关于deep-sleep模式下功耗过高问题。
This is a regression in recent ESP-IDF versions; we are working on a fix, but for now you can call adc_power_off function before entering deep sleep to reduce the current.
Re: 关于deep-sleep模式下功耗过高问题。
你好,谢谢你的回复。
我们使用的IDF版本是3.1:
1、这个现象是3.1版本才出现的吗,回滚回其它版本是否可以避免这个问题?
2、我们通过增加 adc_power_off 控制,功耗并没有下降。
3、近期是否版本发布计划修复此问题。
谢谢。
Re: 关于deep-sleep模式下功耗过高问题。
The issue is present in IDF 3.1.1 and 3.0.x versions as well; there likely exists a version on 3.0 branch which does not have the issue, but i can't say for sure which one is that.
Regarding adc_power_off not having effect, here's the code i used to test.
If I remove the adc_power_off line, then current is 1.4mA. If i add it back, current is 5.5uA.
Please check with this code sample to see if your issue is the same or not.

Hope this helps! I'll update this topic when the fix makes its way into a release.
