cc @octoate ...wo wir gerade das Thema hatten ;-)
@octoate Zigbee hatte ich lediglich Mal mit den ESP32 s ausprobiert, würde ich aber nicht für Batteriebetrieb empfehlen. Wenn von Nordic, dann entweder 'alten' #nRF52840, damit Du altes nRF Connect SDK nutzen kannst oder neuen #nRF54L15 dann mit #Zephyr. Zigbee samples https://share.google/aHb4LxuU7vJ4xJwX3

I am slowly getting better at soldering, 4 out of 7 successful #MechanicalKeyboard PCBs now - all three of my diode-free #GraphTheory wired keyboard PCB designs have worked (eventually) ⌨️🎊
1️⃣ #RaspberryPiPico #RP2040 ‘Gamma Omega TC36K’ (USB only) http://astrobeano.blogspot.com/2025/08/my-first-self-built-computer-keyboard.html
2️⃣ #ProMicro #nRF52840 BLE ‘Gamma Omega Hesse’ https://astrobeano.blogspot.com/2025/10/hesse-diode-free-bluetooth-keyboard.html
3️⃣ #SeeedStudio #Xiao #SplitKeyboard BLE split Forager ‘Acid’ http://astrobeano.blogspot.com/2025/10/partial-heawood-forager-keyboard.html
So I spent some time optimizing the #MeshCore firmware to use less power on some companion devices.
Especially if you are using devices based on #nrf52840 like #T1000E or #WisMeshTag and want to avoid draining the battery when the device is powered off, you might want to look at https://github.com/meshcore-dev/MeshCore/pull/1122.
Tests and feedback welcome!
My current success rate with #MechanicalKeyboard PCB soldering is currently only 2 out of 5, well 40% is a pass mark - just.
The #RaspberryPiPico #RP2040 ‘Gamma Omega TC36K’ board worked (an easy build, could probably have socketed it). 💚
One success, one failure with #SeeedStudio #Xiao BLE castellated in Forager ‘Acid’ PCB (some fiddly back pads). 🧡
Two failures with #ProMicro #nRF52840 BLE in ‘Gamma Omega Hesse’ board attempting faux-castellation💔
Just as well custom PCBs are fabricated in batches of five - waiting on spare parts to try again - #LearningByDoing or #LearningByFailing ?

If my first wireless Bluetooth #MechanicalKeyboard proves a little battery hungry - and the #ZMK Discord channel suggests the #nRF52840 #ProMicro controller I plan on using can be - there’s an easy fix: Buy a bigger battery! 🪫
In hindsight I was over cautious when I ordered the 300mAh LP602030 battery BEFORE finalising the design, and eked out a few more millimetres for it 😢
Design is here: https://github.com/unspecworks/gamma-omega/tree/main/hesse
The last few days I spent a fair chunk of my day arguing with the nRF Connect SDK and its Partition Manager…
The goal: trying to get NSIB and mcuboot to behave with the secondary image on external (QSPI) flash.
Took the better part of yesterday and today just getting a `pm_static.yml` together… only for it to compile an image, and `west flash` to barf because the image file embedded both on-chip flash data *and* a copy of the bootloader for the QSPI flash.
In the end, I came to the following conclusions:
1. Partition manager is over-engineered and fails at its prime objective of making partition layout easier (they tell you to skip dynamic layout and use `pm_static.yml` when doing DFU… enough said!)
2. NSIB is a no-go if external flash is involved because it *insists* on making a composite image that won't actually load.
Tomorrow, I'll see if I can bend `mcuboot` to my will. Primarily I want to see if I can move the public keys it uses for authenticity checks into a separate partition so I can update those without flashing a whole new bootloader.
