if my esp32 is connected to wifi before going into deep sleep, is there any advantage to issuing the commands:

esp_wifi_stop();
esp_wifi_deinit();

before

going into deep sleep?

I'm thinking perhaps that may tell the AP that the wifi will no longer be required and save resources there, until the ...

I don't get how wi-fi 6 works with the esp32-c6.

I am writing code for an esp32 Wi-Fi 6 Weather Station which will be take readings and then communicating via Wi-Fi to an MQTT server as well as a weather service for a total of about 1 second, and then be asleep for 15 minutes, after which time it ...

I am using the ESP-IDF with the (still in development) version 5.1, and an ESP32-C6.

One of the features of the ESP32-C6 is WiFi support.

How do I enable that in my code?

More specifically, I added:

ESP_ERROR_CHECK(esp_wifi_set_protocol(ESP_IF_WIFI_STA , WIFI_PROTOCOL_11AX));

just prior to ...

Thank you, but adding:


#define FASTLED_RMT_MAX_CHANNELS 1
#define FASTLED_RMT_BUILTIN_DRIVER 1
#define FASTLED_INTERRUPT_RETRY_COUNT 1


In any combination did not resolve the rebooting problem.

Adding
#define FASTLED_RMT_BUILTIN_DRIVER 1
did turn the LED red when it was supposed to, but ...

I have an esp32-s2-saola-1 which has an addressable RGB LED (WS2812), driven by GPIO18 as described here:
https://docs.espressif.com/projects/esp-idf/en/latest/esp32s2/hw-reference/esp32s2/user-guide-saola-1-v1.2.html

Problem is I haven't yet found an Arduino compatible library to drive the RGB led ...

thank you, that was very helpful.

Can anyone confirm the input voltage range for the esp32-s2-saola-1 board; wondering if it can handle 7.5v in?

ESP_Sprite: thank you very much, that was exactly what I needed to know - indeed pins 8 and 9 are the two to use.

Thank you but I really don't understand.

Are you saying I can use any two GPIO pins?

If yes, how do I tell the ESP32-S2 dev board ( ESP32-S2-Saola-1) which GPIO I am using for SDA and SCL?

For example, on a ESP32 Dev Kit 1, GPIO21 is SDA and GPIO22 is I2C SCL - so I just use those two pins.

But ...

please note, at 7:35 there is a reference to running get.exe
on my system I had to run this as an administrator for the setup to work correctly
