Bluetooth Page Turner plugin for Kobo KOReader

[Frenzie]

You'll see soon enough if you try.

(But yes, it should be .koplugin).

I have been trying to make this work on my Clara Colour without success. It gives me an error "Error: No result from the Bluetooth script" even after changing the path in the configuration. Any pointers? I really want to use my 8bitdo device as a page turner with KOreader.

If anyone has managed to get this work on a Clara with 8bitdo micro, can you please share the plugin code with us? I think except the MAC address, everything should be the same?

Thanks.

Output of running on.sh:

/mnt/onboard/.adds/koreader/plugins/bluetooth.koplugin
# ash ./on.sh
insmod: can't insert '/drivers/mx6sll-ntx/wifi/sdio_bt_pwr.ko': No such file or directory

Realtek Bluetooth ERROR: Can't initialize device 2, No such file or directory
Error org.freedesktop.DBus.Error.NoReply: Message did not receive a reply (timeout by message bus)
Can't open HCI socket.: Address family not supported by protocol

When I check /drivers/ there's only the following:

# pwd && ls
/drivers/mt8113t-ntx/mt66xx
wlan_drv_gen4m.ko   wmt_cdev_bt.ko      wmt_chrdev_wifi.ko  wmt_drv.ko

(there's no other directories or subdirectories)

I don't know if these are equivalent, but I tried the following:

# insmod /drivers/mt8113t-ntx/mt66xx/wmt_cdev_bt.ko
insmod: can't insert '/drivers/mt8113t-ntx/mt66xx/wmt_cdev_bt.ko': File exists

and the same output for all other files listed here.
Anyways, if you could point me in the right direction (or tell me there's no easy solution) that would be greatly appreciated.. Thank you!

I get the same error. I have checked the event(4) in mine, and tried different tests but I am unsure why its giving me this error. I'm at wit's end here, and tried chatGPT but I feel this is just the blind leading the blind(er)...

Trying this on the KCL.

Any updates on the Clara BW? Trying to get it set up now.

If I’m not mistaken, currently there is no known way to use Bluetooth page turners in KOReader on Clara BW, Clara Colour, or Libra Colour devices.

I have a Libra Colour, and been poring over forums for days trying to figure out a solution. Trying to use it with an 8BitDo Micro. I’ve tried using the .btpt plugin as well as the native drivers. Both let me use the clicker

As far as I can tell, it comes down to the string that need replacing on the on.sh file. And that string is not known. I anyone has any suggestion on how to find that string for these devices it should hopefully solve the problem.

Update: Ignore this post. I was able to figure out how to set up bluetooth page turners on KOReader. See my next post below.

For anyone interested, I was able to figure out how to set up bluetooth control for KOReader on the Libra Colour. Took me almost 3 days to figure it out (countless tries, crashes, reconnections etc.). The instructions do not rely on a plug-in, so they should work on other devices as well. This thread and others on mobileread were very useful. Anyway, I've created a new post with instructions. Here's the link -- https://www.mobileread.com/forums/sh...d.php?t=370120

I had wanted to move the SDL (desktop) gamepad support away from its hardcoded semi-poc state but I hadn't considered that it could potentially be of benefit to actual ereaders as well.

Out of curiosity, do you recall if the KOReader logs showed any kind of keycodes for the gamepad prior to mapping it as a keyboard?

I have only ever used evtest for key codes and that's not that reliable to give you a clear picture. It becomes tricky if you don't know what button is being fired from the keyboard.

Update 0.4.0: Bluetooth Plugin Update: Font Controls & Bank System

New Font Control Events Added
The Bluetooth plugin now supports comprehensive font and typography controls:
Font Cycling Events:
BTCycleFontHinting - Cycle through font hinting options (off → native → auto)
BTCycleFontKerning - Cycle through font kerning options (off → fast → good → best)
BTCycleWordSpacing - Cycle through word spacing options (small → medium → large)
BTCycleWordExpansion - Cycle through word expansion options (none → some → more)
Font Adjustment Events:
BTIncreaseFontWeight / BTDecreaseFontWeight - Adjust font weight by ±0.5 units
BTIncreaseLineSpacing / BTDecreaseLineSpacing - Adjust line spacing by ±5%
Display Control Events:
BTIncreaseBrightness / BTDecreaseBrightness - Frontlight brightness control
BTIncreaseWarmth / BTDecreaseWarmth - Frontlight warmth control


Bank System for Limited Button Devices
Introducing the Bank system. Many Bluetooth controllers have limited buttons (4 to 14 buttons), but you want access to 20+ different functions, The new Bank System allows you to use the same physical buttons for different functions by switching between "banks" of button mappings. Instead of mapping buttons to explicit functions, you can set them to generic BTActions which act as a single level of indirection and allow you to execute different functions with the same buttons. Using the banks is completely optional. If the user doesn't map buttons to BTActionX type events and continue to use hardcoded events, the system will continue to work.

How It Works:
BTAction1-20: Universal action mapping that changes based on current bank
Bank Navigation: Use dedicated buttons to switch between banks. Using BTRemoteNextBank and BTRemotePrevBank functions.
Bank Persistence: Current bank is remembered across sessions
Easy Configuration: Define banks in bank_config.txt Keep this in the plugin folder as everything else.

Example Setup:
Bank 1: Core navigation (chapters, pages, bookmarks, brightness)
Bank 2: Font controls (hinting, kerning, spacing, weight, line spacing, warmth)

Perfect for small controllers, page turners, or any device with limited buttons that needs access to many functions.
The bank system transforms your limited-button controller into a powerful, multi-function device. By sacrificing 1 or 2 buttons for bank navigation, you can now map all functions onto your remote.

Detailed explanations are available in the repository readme.

I connected a regular game controller to the Kobo Libra Colour, just to see what event codes it provides. I got the following output -
Event code 304 (BtnA)
Event code 305 (BtnB)
Event code 306 (BtnC)
Event code 307 (BtnX)
Event code 308 (BtnY)
Event code 309 (BtnZ)
Event code 310 (BtnTL)
Event code 311 (BtnTR)
Event code 312 (BtnTL2)
Event code 313 (BtnTR2)
Event code 314 (BtnSelect)
Event code 315 (BtnStart)
Event code 316 (BtnMode)
Event code 317 (BtnThumbL)
Event code 318 (BtnThumbR)

The event capture response kept going on continuously even without pressing any button on the controller. It may have been the thumb-sticks constantly reporting their position, or perhaps the Gyro control output being reported continuously. Not sure. I did not play around with it too much. But it did lead me to believe that since event codes were reported, a regular game controller should work just the same as a bluetooth keyboard.
