How integrate  bluetooth printer in Kivy ?

platforms : osx, iOS, android, windows

Kivy not supporting  pybluez.

plyer.platforms.macosx.bluetooth can help only for bluetooth is on/off info only, It won't help on connecting, printing, but even this is also not working. :(

Plyer OSXBluetooth coming as None  

<plyer.platforms.macosx.bluetooth.OSXBluetooth object at 0x117ca4df0>

from kivy.app import App
from kivy.lang import Builder
from kivy.properties import ObjectProperty
from kivy.properties import StringProperty
from kivy.uix.boxlayout import BoxLayout


Builder.load_string('''
#:import bluetooth plyer.bluetooth
<BluetoothInterface>:
bluetooth: bluetooth
orientation: 'vertical'
padding: '50dp'
spacing: '20dp'
BoxLayout:
orientation: 'horizontal'
size_hint_y: 0.3
Button:
text: 'Get Bluetooth status'
on_release:
root.get_info()
Label:
text: str(root.text)
Label:
text: str(root.info)
''')


class BluetoothInterface(BoxLayout):
'''Root Widget.'''

info = ObjectProperty()
text = StringProperty()

text = "Bluetooth: "

def get_info(self):
self.info = str(self.bluetooth.info)


class BluetoothApp(App):
bt = BluetoothInterface()
def build(self):
return self.bt
def on_pause(self):
return True


if __name__ == "__main__":
BluetoothApp().run()

Bluetooth is orthogonal to kivy.  Is there a specific problem using kivy with pybluez?  I would expect it would be simple to integrate.

 

I did a quick search and found this list of Bluetooth libs: https://github.com/ukBaz/python-bluezero/wiki

This is not a kivy issue, but it looks like you are missing a dependency of the bluetooth library.

Did you follow the instructions?  https://github.com/pybluez/pybluez/blob/master/docs/install.rst

It looks like you need to pip install lightblue
