Bootloader OTA GPIO Trigger Factory Reset Increase Power Consumption

Postby Cantonius99 » Sun Jan 02, 2022 9:19 am

Hello,

I'm working on OTA and set the GPIO Triggers Factory Reset Flag in the Bootloader (in MenuConfig).

However, I now notice that the power consumption has increased from 58uA to 200uA. Is this expected behaviour and is there a way to decrease the amount somehow?

Thank you!

Sorry about that!

When in deep sleep it used to be 58uA. But when GPIO Trigger Factory Reset is On, power consumption is 200uA during deep sleep.

Not sure what happened to my previous entries. Perhaps Mods need to verify it first. But looks like I have fixed the issue:

I was working on OTA and enabled GPIO Trigger Factory Reset. However, that same GPIO is used for external wakeup as well. Deep sleep measurements went from 58mA to 185mA after enabling this so was wondering what the cause was. Turns out it was the external circuit that was causing extra current flow.

rtc_gpio_isolate on that gpio helps to prevent the current flow.

Your first 3 posts need to be approved my a mod first, indeed. Glad you got it resolved!
