NRF52840 MDK USB DONGLE: From zero to hero?

[gesnaud]

Hi community 👋🏼!

I've bought a tiny NRF52840 mdk usb dongle few months ago and from this time, I struggle to understand how to use it...
Here is a thread i started weeks ago on nordiczone, where i explained that i cannot make Zigbee sample working...
Blinky, hello_world are ok, but I need Zigbee for a project and I'm in a dealock...

• My first was to have a working development environment ✅
• Second one was to make hello_world ✅
• Third one make a dummy zigbee end device recognized in Home Assistant ❌

I'm able to have a zigbee/shell sample working thanks to nrf sdk v2.9.0 and not Makerdiary SDK... But once this zigbee shell firmware uploaded in the board I have no way to start the shell because... the sample is not configured for USB connection 😭

NOTE: I tried the zigbee shell from makerdiary SDK and it is not working...
(I will copy/paste error logs here later)

Please help me 🙏🏼!

Have a nice day 🖖🏼!
