2.4 GHz Support Possible? #8

Hi,

Thanks for making Jorne. It seems one of very few split keyboards that take into account the greater number of letters in Cyrillic alphabets.

I was wondering if Jorne could implement 2.4 GHz connectivity. Perhaps along with Bluetooth? I need to enter a password early in the boot process, before OS loads, which is why I find 2.4 GHz more suitable. Plugging wires in and out would be a drag.

I haven't found anything on this in the wiki.

Yea. Stock mitosis firmware and nrfmicro will do the trick. I haven't tried that because I don't like dongles that but it should not require any changes at all.

You'd need matrix suport, so check out mitosis clones with diodes https://github.com/joric/bluetosis/wiki/Alternatives redox wireless probably.

So, all in all, it means I could assemble a Jorne based on this guide...

...next, assemble a Redox receiver, flash this receiver with this firmware...

...then get two NRFMicro boards based on this schematics, flash them both using a version of ZMK...

And everything should work, basically?

joric commented 3 years ago

except ZMK is not related to this at all. you flash both nrfmicros with a slightly modified (maybe even unmodified, chips are basically the same) redox transmitter firmware (left and right) and flash the receiver with redox receiver firmware.

You don't really need to order PCB for the transmitter, all you may just solder any nrf51/nr52 module to 3.3v pro micro via uart pins as here https://github.com/joric/jorian/wiki/Soldering#receiver it only need 4 pins to solder - RX,TX,VCC,GND.

So, in the end, I can get away with:

  1. three Pro Micros, or similar boards
  2. three NRF42's soldered onto Pro Micros

Right?

joric commented 3 years ago

wrong. YOU DON'T NEED PRO MICROS (except for the receiver). also there's no such thing as nrf42

glow12121 commented 3 years ago

Okay, two Pro Micros used in the wired model go away, while two YJ-14015's step in for the wireless model, right?

Could you clarify whythere's no such thing as an NRF52? You mentioned, "you may just solder any nrf51/nr52 module to 3.3v pro micro."

42

Cool, thanks.
