#ZephyrOS has a pretty cool http server demo that runs out of the box on many of the supported boards. It can even toggle the LED used in the blinky demo through the browser. It drove my crazy that on my mimxrt1060-evk, the network always lost connection when the LED was toggled. After some unsuccessful debug attempts and #wireshark traces, I finally downloaded the schematics and took a look 🙈

How do you maintain Bluetooth range in a fully metal-enclosed BMS? One customer’s design initially had <1m range due to shielding. Fixes:

🔹 Structural tweaks: Added openings near plastic connectors (485/4G)
🔹 Antenna repositioning: Moved closer to non-metal sections
🔹 Component upgrade: Switched to ceramic antenna

Result? 10m+ range despite the metal shell! Lesson: RF performance hinges on mechanical + electrical co-design. #IoT #BLE #Embedded #Hardware #BMS

#MI6 #Embedded With #Syria's #AlQaeda Government”

by Kit Klarenberg in Global Delinquents on Substack

“If #Starmer’s unelected security chief is [..] scripting foreign policy thru #InterMediate, then Britain is no longer merely meddling in West Asia but is also governing it by proxy. & if #Powell’s loyal Al-Qaeda client in #Damascus is the new face of ‘liberal interventionism,’ it is clear the #colonial playbook has not simply returned – it in fact never left”

Global Delinquents · MI6 Embedded With Syria's Al Qaeda GovernmentBy Kit Klarenberg

Exploring how #BluetoothTech is shaping the future of #SmartHome systems! With low-power BLE (like the KT6368A chip), users control lights, appliances & security effortlessly. Key perks:

🔹 Local/remote device management
🔹 Energy-efficient automation
🔹 Secure data transmission (FHSS)

Bluetooth 5.1 takes it further—faster, longer range & better IoT scalability. Are you using Bluetooth in your home setup? Share your experiences! #IoT #HomeAutomation #Embedded

Good news Homebrew friends! :) Now bmputil-cli has a formulae you can use to install it. This should simplify things especially for those that manage a lab with a bunch of machines! :) All you need to do is run `brew install blackmagic-debug/blackmagic/bmputil-cli` and profit! github.com/blackmagic-debug/ho #opensource #debugging #embedded #electronics #rust #macos #homebrew

It would also be a more flexible option not just for "dumb #terminals" like a VT320 or VT525, thus desireable for a lot of #legacy / #embedded setup and allow for integrating like a #serial #console into a "Managment LAN" (which should be #airgapped!)…

  • Also an #EthernetModem would really be a cost-effective option compared to proprietary solutions, espechally when one can make a #DINrail-mounted version.

So yeah, a #LAN232 / #Ethernet232 would be kinda cool, even if it's just a #PiZero 1.3 with a USB Serial & Ethernet Chip in a case.

Everyone and their mom has a #Wifi232 to get their #VintageComputer online, but I wounder if there's a #wired (#LAN) option instead.

Background: In my area, 2,4 GHz WiFi is so overcrowded that it's basically unuseable and also because Ethernet is more reliable.

I don't mind if it looks like a MAU but with like a unmanaged 4-port Gigiabit Switch for #10Base2 / #10Base5 - lookalike "passthrough" and internal 10 MBit/s port so it can be used to directly link units or be hooked up to a switch. Similar to FriendlyNet

So technically it's closer to a DEC DELNI than real AUI but if someone wants to implement an #AUI and even add a an AAUI adaptor cable I'm not gonna tell anyone not to.
