You need a stronger pullup than what is included in the pump control circuit there. Try a 10K. From your description, this is happening when the device restarts, so it literally can't be a problem in your code (which isn't running during a restart). You say there's more involved in the circuit- I am...

Put a 10-50K pullup resistor on the pins you want to stay high. When the device resets, there is not going to be any signal delivered on those pins, so you need to provide a default one.
You should choose a pin other than 12, which is a strapping pin that needs to be pulled low for 3V3 flash.

The development version is currently at 3.0.0-beta1, which has support for the C6 (and H2) boards. If you prefer to use platformio, you can use Jason2866's packages that I linked above. The link shows what you add to platformio.ini. arduino-esp32 is built on top of ESP-IDF. So, you can use almost al...

Platformio does not seem to support the boards yet (it only supports stable versions of esp-idf extension)

Jason2866 maintains a repo with frequent release packages for platformio.

You need to include the header file in your code (`#include <WebSocket.h>`)
If you need more help, please provide code and a link for the library you are using.

You can do a printf directly into the response method in a for loop. This will stream it, and likely is breaking it into mtu-sized chunks to deliver on the line.

I assume this is data that you actually want to log anyhow. Write it to a file, and then staticServe that file.
If you want a lightweight data logger that's a bit more sophisticated, take a look at rrdTool

If you are a bit clearer about what you mean, we can help you much faster. There are AsyncUDP and AsyncTCP libraries for arduino-esp32. They both run FreeRTOS tasks which then reach down to directly access the ESP-IDF functionality. The ESP-IDF framework uses a customized version of LwIP ( esp_lwip ...

If you are just sending a file from the flash, you can use the serveStatic method. https://github.com/me-no-dev/ESPAsyncWebServer?tab=readme-ov-file#serving-specific-file-by-name The mime type would be "text/csv". I would recommend you add a max-age header at the frequency that you are collecting th...
