Re: ESP32 websocket client misses first received message

Issue still exists. My current workaround is to add a delay on my Python server before sending any messages since the first message gets dropped on the ESP32.

Re: Getting 5V for MCP2515

The mcp2515 has an operating range of 2.7 to 5.5V. You shouldn’t have an issue operating at 3.3V unless there’s something I’m missing.

Re: Two version de esp-idf in diferents directories

I’d highly recommend doing this inside a docker container. I just upgraded a large code base from 4.4 to 5.1 by using a devcontainer that was set up for esp-idf 5.1. Going back and forth between different IDF versions can be a big pain because of all the tool chain and python dependency issues.

Re: Espressif Reveals ESP32-P4, So close to perfection

Not every microcontroller needs WiFi and/or ble. This looks like an excellent competitor to STM’s f7 series micros. Can’t wait to start using the P4 in my designs! I’m glad you all finally have another micro with an embedded Ethernet MAC.

Any idea on approximate-ish, sorta release date?

Re: Software UART in ESP32-S3

Here’s an example of using the rmt peripheral as an extra UART. Note that I’ve never used this library. https://github.com/naffej/esp32-rmt-uar ... rmt_uart.c

Re: Problems defining component that uses code generation

I know this is well after your original post, but if you're still having issues, let me know and I'll share a copy of my cmakelists that generates some code successfully.

You should just be able to move your add_dependencies outside of the CMAKE_EARLY_EXPANSION check and it should work.

Re: Can I delete pins 17-22 from the wroom-32d footprint?

@mikemoy, mainly to reduce vias for some high-frequency rmii signals.

@ESP_Sprite, thanks for the tip, that is an excellent idea.

Can I delete pins 17-22 from the wroom-32d footprint?

Is there any issue with deleting pins 17-22 from the footprint and routing traces under them (protected by soldermaks, of course)? See attached screenshot.
