Re: Auto light sleep doesn't seem to work with 2.1.x NONOS SDK

A while ago, I had the same question.
viewtopic.php?f=7&t=5680

As I understand it, in light sleep mode the clock is off and the esp only wakes up periodically because of the beacons of an ap the esp is connected to. If there is no ap, it oversleeps. I stopped using light sleep mode... it is unfortunate.

Of course you can, that's what light sleep was intended to do.

Btw, I just found out that this issue does not happen in NONOS_SDK 2.0.0. Light sleep is working. 2.1.0 and above it seems to be broken.

Hoping to get an answer from Espressif as this seems to be a major issue.

AFAIK, you cannot sleep if there is a timer enabled. I think you can find more details in the API guide or sleep guide. http://www.espressif.com/en/support/download/documents

Auto light sleep doesn't seem to work with 2.1.x NONOS SDK

2017-11-13T09:12:14+08:00

So I just migrated from 1.5.4 to 2.1.x and enabling auto light sleep doesn't seem to work!

My timers run for a few iterations before I get the UART output "pm open, type 1: 1 0" and then the timers stop. It looks like my timers stop once auto light sleep is enabled.

Not really sure where to look ...

Thanks for any help you can provide.
