General issue report

ESP-AT version v3.4.0.0

If I enable Ethernet and send a sleep command, it does not enter sleep. If I build without Ethernet and send the sleep command, it will enter sleep mode normally. sdkconfig

CONFIG_AT_ETHERNET_SUPPORT=y CONFIG_PHY_RTL8201=y

I would like to know how to enter sleep mode when using Ethnet.

Thanks Sungsu

@charon22 We sincerely apologize that esp-idf has not yet optimized the power consumption for Ethernet usage. This means that when Ethernet is enabled, the module may not be able to enter light-sleep, resulting in relatively higher power consumption.

If this feature is essential for your product, we kindly suggest submitting detailed requirements to esp-idf issue.
