Standalone keyboard not registering keystrokes

Hello there,

I received my standalone keyboard last week. I received it without switches, I installed Kailh Choc v1 Purpz in it.
It doesn’t register any keystroke.

I tried:

  • on a Windows PC
  • on a Linux PC
  • with the included USB-C cable
  • with another USB-C cable from another keyboard

But so far, I only see the MNT RE logo on the OLED screen and the lightings below the switches.

I’ve looked so far:

  • in the community forum
  • in the gitlab server
  • in the handbook

but I didn’t find where to start debugging this.

Thank you for any help!

Can you post what appears in sudo dmesg -w when you plug the keyboard in? Kinda sounds like it may be stuck in firmware update mode.

Thank you.

Here’s an excerpt of output of the command related to the USB Keyboard (the log is too long), regarding the USB keyboard.

The process hang after that so I stopped (Ctrl-c)

That looks how I would expect. Have you tried flashing the latest firmware yet?

Yes, I followed the instructions of Paul from MNT.
Same result , still not working…

Could it be hardware?
I received it without switches and I put switches inside, hotswap. I checked that the pins were straight everytime but maybe I missed something else to do?

@vkoskiv I didn’t realise that I needed to solder the switches :man_facepalming:. I’ll keep you posted. Thanks for taking the time to answer my questions.

That was going to be my next question :smile:

Glad you got it figured out!

I didn’t figured it out, I got help from MNT’s Paul :grin: . I am just a humble beginner in this kind of field…
