TIme for ESP32-C6 to wake from light/deep sleep

How long, approximately, does it take for for tje ESP32-C6 to wake from light vs deep sleep?

I realize it will depend on all kinds of things but in general under ordinary conditions are we talking microseconds, milliseconds, hundreds of milliseconds? How does it differ for light versus deep sleep?

which GPIO pin is connected to the physical knob on the side of the lilygo T-Watch S3?

On the LilyGo T-Watch S3 2020, which GPIO pin is connected to the physical knob on the side of the watch? I'm aware of the schematic https://github.com/Xinyuan-LilyGO/TTGO_TWatch_Library/blob/t-watch-s3/schematic/T_WATCH_S3.pdf but I can't find the knob in that schematic. I have also looked through ...

Where to ask questions about lilygo t-watch development?

Does anyone know where is a good place to ask questions specific to the lilygo t-watch?

My question is: where can I find the code for the demo firmware that comes preloaded onto the watch?

ESPNOW messages being dropped

I have 13 ESP32-C3 devices in a room sending messages at a rate of up to 10 messages per device per second. All the devices are within wifi range of each other, and all the messages are sent as single-packet ESP-NOW transmissions. Each message is sent on the same wifi channel, and all messages are b...

Get a synchronized WIFI TSF when using ESP-NOW?

I'm using ESP-NOW for communication devices but I am also relying on the WIFI TSF to be synchronized across all my devices. What I'm seeing is that with ESP-NOW there is no need to connect to an access point, so the WIFI TSF is zero. Is there a way to get a synchronized WIFI TSF while using ESP-NOW?

Can I access the low-level RF encoder/decoder on the ESP32-C3?

Can I get access to the low-level RF encoder/decoder on the ESP32-C3? I would like to send and receive my own signals using the 2.4 GHz antenna, outside of the bluetooth/wifi protocols. The reason I want to do this is for an ultra-low latency application in which I only need to send extremely simple...

Re: ESP32-C3-DevKitC-02 ADC bias drifts a lot over time

Very helpful -- thank you! I am now eliminating the bias drift in software and it seems to be working great.

Give a list of wifi networks and passwords to try

The building I live in has two wifi networks and I would like my esp32c3 to try connecting to both of them. Is it possible to provide multiple ssids and passwords to esp_wifi_set_config so that if any of the listed networks are available then my device will connect to that one?

Multiple "main" targets in a single project

I have a project that involves a few ESP32 chips running different software. I would like to set up an ESP-IDF project in which there is more than one "main" target that I can build. So I would like to be able to run ninja main_abc and ninja main_xyz or something like that in order to build differen...

ESP32-C3-DevKitC-02 ADC bias drifts a lot over time

I am using the ADC continuous mode driver with ESP-IDF v5.1 on an ESP32-C3-DevKitC-02. I am reading from an adafruit MEMS analog microphone SPW2430 (https://www.adafruit.com/product/2716). During 10 seconds of data recording, I see significant drift in the "zero point" of the microphone. Here is 10 ...
