Re: Light Sleep unexpected Behaviour.

Very disappointing in comparison to what is stated in the data sheet and in comparison to what is stated here viewtopic.php?t=133

Thanks for investigating.

Re: Light Sleep unexpected Behaviour.

So, light sleep is not working reliably even with today’s SDK 2.0?

Best regards,

Re: Some power saving questions

@Espressif_Faye: Deep sleep is a great feature that enables battery applications. This is particularly helpful when sensor data is transferred with long time interval like 10 minutes. But how can we reduce regular power consumption when NOT in deep sleep? For applications that need to check switches...

Re: Some power saving questions

I like to support this request and comment: . If a full reset is involved, I would prefer storing in Flash rather than RTC ram. . Success of speeding up connecting and DHCP lease might depend on access point behavior/settings. . Power consumption might be optimized with .. TX power. Already asked fo...

IO voltage pins

Hi, Specification states: VDDIO(min): 1.7V VDDIO(max): 3.6V Thus, I assume, IOs can operate at 1.8V, 2.5V and 3.3V in dependece of VDDIO, which is great. Reference schematic states: IO_VDD=VDDPST There are two VDDPST pins on the package. On on the bottom and one one right hand side. Are those VDDPST...

Re: Inverse UART output? (for WS2812 )

As I am playoing around alot with the WS2812b.... Could UART actually be used as the pulse widths determine the "0" and "1"? I don't now. But the idea in more detail is the following: WB: Number of WS2812 Bits per UART Char USYMB: UART Symbols per UART Char inclunging start-bit ...

Inverse UART output? (for WS2812 )

********** ********** EDIT: NOTE for those who try this: After the start-bit, the UART sends LSB first. ********** ********** Hi, is it possible to inverse the output of the UART. Output 1 instead of 0 and 0 instead of 1. Background of Question: Using the UART for controlling WS2812 after the follow...
