Support bluetooth/2.4Ghz

[strodgers]

Currently the keyboard is only controlled over usb cable, would be nice to include wireless

I can understand bluetooth but why does it throw an error when i run any command while the connection method is 2.4? isn't it basically the same? fyi i'm trying to read the battery percentage value from the keyboard while it's on 2.4g mode, that way i can write a script that checks the battery percentage every once in a while and if let's say the percentage is under 20%, it'll send the user a notification that the keyboard should be charged.

I know this is possible, because it's visible in the epomaker driver app while the keyboard is on bt or 2.4 mode:

on wired it doesn't show anything probably because it's redundant (i think?)

yea good point about 2.4Ghz, it should just be the same, I just havent gotten around to testing it all yet. Maybe I'll try it today then.

Oooo that sounds like a cool feature! do you mean to add it to this project or do you have another one? any idea how the information is retrieved from the keyboard about battery level?

No idea how it is done in the app, I was able to narrow the driver's source code down to C:\EPOMAKER Driver\resources\app.asar.unpacked\dist\index.js, made the code readable using prettier 3.3.3 but well... the file is 300k lines long and i have no idea how the app communicates with the keyboard. I tried doing ctrl+f and searching for any "battery" mentions, there are a lot but I'm not good in js so i have no idea how all that works. It's one of those shitty electron containers (i could tell from the folder structure, it's identical to programs like Discord, Notion etc.). Normally you should be able to open devtools in an electron app, but this one won't budge so I suppose it's a lost cause.

Afterwards I installed wireshark to capture all traffic between the computer and the keyboard (after applying a lot of filters), seems promising but it's in binary/machine code and i have no idea how all that works:

However, it is possible to retrieve the battery percentage when it is in bluetooth mode, i made a quick implementation for this today which you can find on my profile (keep in mind that my device is a TH80 pro, so the properties might be different. I suggest you take a look at the source code first)

Hey sorry for the hiatus again

Thanks very much for all the info on this! I will take a look at your TH80 implementation.

I have no idea about node js/electron etc, but there must be some communication about battery level going on somewhere in the wireshark dumps. I will make another issue for it, since this one is more just for bt/2/4GHz support

On the subject of 2.4Ghz, I tried just changing the product ID to the corresponding 2.4Ghz usb adapter but no avail, the controller seemed to think it could still communicate with the keyboard (claimed to be able to send updates to it) but nothing was actually happening, so need to investigate more

[strodgers]

Tentative support for 2.4Ghz now in branch add-24ghz-support
Seems I needed to poll the device before trying to send any further commands
Uploading images does NOT work yet using wireless

One thing I noticed is that when polling, I still see these interrupts being sent from host -> device every now and then which doesn't happen when using the official driver, not sure if thats going to be a problem

[devil304]

If any 2.4Ghz support was figured out, then why it's not in main branch. Branch with 2.4Ghz is now very outdated. I am using my RT100 on bazzite using 2.4Ghz, so I'm interested in this implementation.

[devil304]

I've tried porting that trick with pulling to current version but no luck. No matter what I tried it's not working. Command behaves like it is working and I added log to pulling command and it's saying that it's pulling but no changes on keyboard.
@strodgers Can 2.4 GHz branch be updated to current main version?
I don't need to upload images ar change backlight color's, I need to send time, temperature and CPU usage

[kbrddestroyer]

I'll merge main into wip branch

[kbrddestroyer]

@devil304 I merged current main branch into 2.4GHz wip branch
Please tag me if you'll have any issues with that

Ok, thank you! I will check it out as soon as possible.
