ESP32-C6 - high light sleep current

[michapr]

Board

ESP32-C6FH4

Device Description

Dev-board

Hardware Configuration

no hardware attached in this time

Version

v3.1.0

IDE Name

Arduino IDE

Operating System

Win 11

Flash frequency

80 MHz

PSRAM enabled

no

Upload speed

921600

Description

Cannot get the device in correct light sleep mode, will get current >250uA instead of the published 35uA

In deep sleep all is working as expected (<10uA). How the deep sleep sample must be modified?

I've tried all sorts of things, but nothing has helped...

@michapr Can you please try latest actual Arduino core and if the behaviour is still there Arduino core 3.2.0-rc2?
