Bluetooth page turning for Kobo eReaders

Thanks to you. I just found out about it in this thread. I didn't know it works out of the box in Moon+ Reader.

This is to install the Webserver in Kobo:
$ wget https://github.com/tylpk1216/KoboPag...0/KoboRoot.tgz

$*cp KoboRoot.tgz /run/media/jospalau/KOBOeReader/.kobo

This is the Android app:
$ wget https://github.com/tylpk1216/KoboPag...HTTPClient.apk

It shouldn't be difficult to make a simple app for IPhone to so something similar or maybe there is something similar to Task.

I made a simple Linux demon to use the headphones like this:

import subprocess

from evdev import InputDevice, categorize, ecodes


dev = InputDevice('/dev/input/event24')


print(dev)


def getKey():

for event in dev.read_loop():

if event.type == ecodes.EV_KEY:

c = categorize(event)

if c.keystate == c.key_down:

yield c.keycode


keygenerator = getKey()

while True:

c = next(keygenerator)

print(c)

if c == 'KEY_PLAYCD': subprocess.run("curl http://192.168.50.101/right", shell=True, check=True)

I spent a bunch of time last Friday setting up the $5 ($7 for me) bluetooth camera remote previously mentioned.

I had weird missteps along the way but it did indeed work with the Reddit-linked steps.

My main problem is figuring out how to use NickelMenu to toggle bluetooth. I am able to turn it on and off AFTER the bluetooth switch is turned on in the settings. I suspect it's a "hardware" switch. As I have to do it every time I turn on the reader it feels clunky.

I had an idea that maybe rfkill would turn it on but apparently /dev/rfkill doesn't exist.

[admin@io root]# rfkill list bluetooth
rfkill: /dev/rfkill: No such file or directory

Here's what I ended up with in NickelMenu:

menu_item :reader	:Bluetooth (toggle)	:cmd_output	:500 :quiet :/sbin/lsmod |/bin/grep uhid || /sbin/insmod /mnt/onboard/.adds/kobo-libra2-uhid-module/uhid.ko
  chain_success:skip:2
    chain_failure			:dbg_toast	:problem installing uhid module
    chain_always:skip:-1
  chain_success				:cmd_output	:500 :quiet :/bin/bluetoothctl list |/bin/grep -q Kobo
    chain_success:skip:2
      chain_failure			:dbg_toast	:please start bluetooth from settings
      chain_always:skip:-1
    chain_success			:cmd_output 	:500 :quiet :/bin/bluetoothctl show |/bin/grep -q "Powered: no"
      chain_success:skip:3
        chain_failure			:cmd_output 	:1500 :quiet :/bin/bluetoothctl power off
        chain_success			:dbg_toast 	:bluetooth turned off
        chain_always:skip:-1
      chain_success			:cmd_output 	:1500 :quiet :/bin/bluetoothctl power on
      chain_success			:dbg_toast 	:bluetooth turned on

As you may grasp from the mess above (I'm still learning best practices with NM), bluetoothctl doesn't work unless you go into the reader's menu and turn the device on which makes it available as a controller. It turns off again and disappears from bluetoothctl when the network drops or the reader is in standby.

I don't really want to mess with stopping/starting bluetoothd.

You might want to ask this in the Nickelmenu thread. Geek1011 mentioned over a year ago he would look into turning on/off bluetooth in NM when he got time, see post #645. I would like to see this work too!

This is the exact page turner discussed in the above article; color doesn't matter -- I have both the blue and the white, and both work fine. The rechargeable internal battery lasts for a very long time on a charge; I've yet to have to recharge and I've been using them heavily for many weeks. Single press pages forward; double press pages backward:

https://www.aliexpress.com/item/1005002613561422.html

This is my relevant Nickel Menu code:

menu_item :main    :Bluetooth Patch (toggle) :cmd_output       :500:quiet :rmmod -w /mnt/onboard/.adds/kobo-libra2-uhid-module/uhid.ko
  chain_success:skip:3
  chain_failure                              :cmd_spawn        :quiet :exec /mnt/onboard/.adds/kobo-libra2-uhid-module/run.sh
  chain_success                              :dbg_toast        :Page turner ENABLED
  chain_always:skip:-1
  chain_success                              :dbg_toast        :Page turner disabled

Could you share the config file you are using? I'm trying to get it to work on my Clara 2e and I've tried all the configs I've been able to find with no luck.
Also, I noticed that when I connected a bluetooth speaker, it added this to the Kobo ereader.config.

[BluetoothSettings]
DefaultAudioDevice=/org/bluez/hci0/dev_28_F0_01_D3_5E_C7
LeftVolume_org_bluez_hci0_dev_98_52_3D_E8_DE_F0=12 5
RightVolume_org_bluez_hci0_dev_98_52_3D_E8_DE_F0=1 25
SoftwareVolume_org_bluez_hci0_dev_98_52_3D_E8_DE_F 0=false

Is there anything like that in your Kobo ereader.config with a working device?
By the way, I reset my reader which took that out so it wouldn't interfer and I am on the original firmware as well.

Thanks!

Good idea. I asked some questions and shared some information there.

I noted that it takes me about 9 screen taps after waking up from sleep to re-enable Bluetooth which gets old. And if I use the book to help me sleep, I end up doing this several times a night until I give up and use the reader buttons.

First world problems.

Hello,
I bought thisTiktok ring https://www.amazon.fr/dp/B09YHMGY8P?...roduct_details for my Libra 2, I patched kobo-libra2-uhid-module using the guide https://github.com/tylpk1216/kobo-libra2-uhid-module but the ring still not works in my case .

Here the config file on my Kobo:

prevPage EV_ABS ABS_Y 3500
nextPage EV_ABS ABS_Y 200

I try to go deeper in order to understand the problem...

[tylpk]

If your ring device can appear in /dev/input/eventXX (XX means number for your ring device), you don't need to use kobo-libra2-uhid-module.

If your evtest report is from the Linux of Kobo, the value is hexadecimal. When you use kobo-btpt, you need to convert the value to decimal number.

The ABS_Y is for the location of touching panel, I am not sure whether you can use it in kobo-btpt.

In my experience, the evtest of PC Linux can get more information when you use bluetooth device. You can get the right event, like EV_KEY - KEY_VOLUMEDOWN ...

Then you can use suitable event in kobo-btpt.

[druss67]

Hello,

the events shown are coming from a Linux PC. Unfortunately I am no more able to test this because my Libra 2 bricked during an update. Back to the supplier.

Thanks for your sharing tylpk.

Too bad. Next time if you get a replacement try to remote into the device. Not only is there evtest, the bluetooth page turner code puts debug data in the event log, which helped me find my way to a solution.

[shiplap]

I'm trying to get the same remote working. When I telnet into the device and try to run evtest to figure out what inputs to use, it tells me evtest is not present.

Can't find my logs either, I hit the save to file option in Nickelmenu but can't find any files on the device.

Figured I'd try all the keys I could think of that might match, but still not triggering anything:

nextPage EV_KEY KEY_NEXT 0
nextPage EV_KEY KEY_VOLUMEDOWN 0
nextPage EV_KEY KEY_DOWN 0
nextPage EV_KEY KEY_PAGEDOWN 0
nextPage EV_KEY KEY_SCROLLDOWN 0
nextPage EV_KEY KEY_FASTFORWARD 0
nextPage EV_KEY KEY_VIDEO_NEXT 0

[retro]

Well, I tried 2 different bluetooth remote devices with no luck

So, I saw this reddit post and ended up buying a SYUKUYU RF Remote Control Page Turner.

Works great! Plus I can use it on all my ereaders.

Kobo should definitely add a page turner to their devices. Certainly an excellent selling point.

It's probable that the commands I'm thinking of are from NiLuJe's fine toolkit. I'm new to this thing. I set up my SSH connection with that package before I messed with the internals.

evtest is on my Kobo Libra 2.

logread is also available. My page turnin' activites from last night from when I turned on Bluetooth to when it went on standby (I fell asleep):

Yeah, sorry about the delay; I've barely had any time for kobo stuff this year...

[kobol2]

I don't get `/dev/input/event3` after pairing and connected my bluetooth pageturner. Any idea how I can troubleshoot?
