Bluetooth page turning for Kobo eReaders

Is it possible to turn on just Bluetooth using NickelMenu?

Will the air fryer take the food out of the refrigerator or freezer and prepare it for cooking? I do have an air fryer and our stove also has air fryer capability which comes in handy when you want to prepare chicken wings, etc. for a larger group.

If we needed more air fryer space, we could borrow one from the in-laws who live close by. But for us, the two draw one works well enough.

We do have a fan assisted oven and one with no fan for when we use the oven. We always use the fan assisted oven. It's a dual-oven built into the wall with the microwave above.

It's implemented in the main branch, but not yet released.
https://github.com/pgaskin/NickelMenu
Users can fork and build until the next release is up. Exact timing of release is a question for @geek1011 .

---

For anyone who wants to hack their way to turning bluetooth on/off without modifying NickelMenu, you can create a shell script or NickelMenu instruction to execute the block from here. Make sure to run WiFi first via nickel or nickelmenu!
https://github.com/onatbas/bluetooth...e5/on.sh#L5-L9
This will run bluetooth, but untested. Nickel won't be notified, so there could be side effects.

Any tips for dealing with bluetooth devices that don't show up in `/dev/input` on the Kobo device (Clara 2E, in this case)?

I have a couple of devices (including the JX-03 that has been mentioned here on this thread) that work very reliably on Android but although they appear to pair with the Kobo (according to the Nickel settings screen and to `bluetoothctl`), no input device is created under `/dev/input`. In fact, I have yet to find a single bluetooth device for which the Kobo *does* create a suitable device node.

Do I just need to keep trying more devices (and/or stop cheaping out on stuff from AliExpress)? Can anyone recommend a device that has been known to work properly with a Clara 2E?

Thanks!

I’m not sure about that device specifically, but some devices require uhid.ko patch to be applied before the device is recognized as an input device. My Clara 2E won’t recognize my device without it. Are you applying it?

If your device is not identifying itself as a keyboard-like device, you may indeed be out of options. I found 2 out of 4 devices that work. The ones that don’t function are marketed for this and that app, like TikTok shutter control With a bunch of buttons etc. I would avoid those and go for single button devices at the very least. But do try uhid.ko first if you haven’t already. It’s in this thread somewhere.

[Renate]

Most buttony Bluetooth thingies use HID over GATT (Bluetooth).
Since they are HID, like USB HID things, they have HID report descriptors.
That says what the buttons (or joysticks) do.
They can say that they are Usage 0x07 (Keyboard) or Usage 0x09 (Button)
When it's 0x07, your system knows what 'R' is and adopts the device as a system device.
When it's 0x09, your system only knows that it's some button and waits for some user proc to do something with it.

I've built both of these styles of Bluetooth devices for different purpose.
I have a utility for analyzing HID report descriptors, but I've never run it on Kobo.
If I can find my Kobo I'll see if I can get it running on that.

Edit: Duh! My Kobo Aura2 apparently has neither BT or USB OTG.

Thank you -- I think this was the part I was missing. I still have a bunch of devices that don't work, but now I have one or two that do, and I'm off to the races. Much obliged to you!

For some reason when I double tap the top button on this it does sleep/wake without me having even coded that so I'm deeply confused as the what I do. This is my current config file

Nothing is working except for some reason double tapping up is causing it to wake/sleep.

I think that there are two things going on here.
The first is that your hid kernel module is junk.
It's translating USB Consumer codes into Misc, which is not necessary.

Usage page 0x0c (Consumer)

(0)c 00b5  Scan Next Track     -> a3 KEY_NEXTSONG
(0)c 00b6  Scan Previous Track -> a5 KEY_PREVIOUSSONG
(0)c 00cd  Play/Pause          -> a4 KEY_PLAYPAUSE

The other problem is that your device is also an absolute pointer.
But I think that they screwed up the report descriptor.
Apparently they are only using one report so it always sends screwed up pointer with each button.

If you have a Raspberry Pi we can experiment further with that.
I don't have any executables for Kobo right now.
I guess that I could make one.

Sadly no Raspberry Pi, just a Windows PC, an android phone, a Kobo, and a dream lol

I ordered this off tiktok shop because I liked how small it was but I think it's probably screwed me.

Oh, this thing has a bunch of different modes.
Also, double clicking generates different codes right in the device itself.
The Amazon page shows using double click for readers.
That seems a hassle to me.

I know I've posted this a zillion times, but here's mine that I built and programmed.
