\o/ i just did a 5-way DKG with one of the "servers" being a xiao esp32s3 over bluetooth LE! \m/

i'm porting #klutshnik to #zephyr it's not very quick, takes a few seconds, but this is creating of a key. decrypting should be much quicker. also i expect this to be faster when done over usb. this is an early PoC, loads of features missing before it can be deployed in production.

ST Nucleo Board Implements STM32N6 Series with Neural-ART Acceleration Support

ooo looks like the #Zephyr SDK is getting caught up (mostly) on GCC and others. New version (in alpha) is GCC 14.3-based, which was released less than a month ago.

Today i made my first hello_world #zephyr board working. I have no idea what i'm doing. But it works ... and feels good just to poke around.:D

My initial impression with #Zephyr RTOS: I suppose all this cruft with the device trees and overlays, the weird west tool, the Repository/Workspace/Freestanding application types, etc. will pay in the end. But I find the nRF documentation confusing and and it took me way more than usual to build a blinky and run it on a dev board.

Gotta learn #Zephyr #RTOS for those very power efficient #nRF MCUs. I have used so many RTOS to this day that I will loose the count: RTX51-TINY, MaRTE, SYS/BIOS (DSP-BIOS), RTIC (RTFM), QNX, VxWorks 653, PikeOS and of course FreeRTOS.

If you're outgrowing Arduino or feel limited by bare-metal and FreeRTOS, #Zephyr might be your next step. It offers built-in drivers and cross-platform hardware abstraction, perfect for scalable, production-ready #embedded systems.

The final #Zephyr episode is out today! Zephyr works with "boards" and creating a custom board definition can be a pain. But I've got you covered! Check out the full video to learn more 📺

Getting #WiFi to work in #Zephyr can be a bit tricky...so, I'm here to help! In my latest video, I show how to configure a WiFi driver for the #ESP32 and make simple HTTP requests. Check it out!

alright i am checking out #tmuxAI. i was a fan of gnu screen(1) in the 90s and early aughts, used it all the time, but my openbsd friends rapidly all adopted #tmux and i joined them.

originally i learned screen just cuz i wanted a way to leave myself on #irc & #zephyr when i was away from a terminal.

anyway this #AI assistant for tmux is seemingly able to operate in sessions, panes, and windows!

if you're really curious about this too it's in #macOS #homebrew today:

The #LinuxFoundation will mentor 21 contributors in the Google Summer of Code 2025!! #GSoC

Despite having lined up many more proposals than last year we got the same amount of slots.

11 for #OpenPrinting, 3 for #AGL (Automotive Grade Linux, 2 for each of #SPDX and #IIO (Industrial I/O), and 1 for each of #SOF (Sound Open Firmware), #Zephyr, and #KWorkflow.

See Google's announcements of the projects:

It's taken a while, but I think I've finally gotten the hang of some of the #Zephyr project/workspace patterns, specifically manifests and "shared libraries”.

Wait, why does IntelliJ Serial Connection plugin not set DTR any more? It definitely used to set it. Down another rabbit hole. #zephyr

OK, somehow this code now blocks forever... what? It should just wait until you connect to the serial console. #zephyr

```c
while (!dtr) {
uart_line_ctrl_get(dev, UART_LINE_CTRL_DTR, &dtr);
k_sleep(K_MSEC(250));
}
```
