bleak compatible pythonista.cb backend

Bleak compatible backend for Pythonista iOS app

This module uses bleak backend API to implement a compatible solution for Pythonista iOS app. It uses Pythonista built-in _cb module, that is wrapper to iOS CoreBluetooth.

[!CAUTION] This project is in early beta use with caution

• This backend refers to Pythonista.cb docs
• This backend refers to existing macOS CoreBluetooth bleak backend was used as a reference
• It also provides stub files for pythonista built-in modules as _cb and pythonista.cb, and fake _cb.py implementation for testing on unsupported platforms
• Use Bleak docs to explore how to use Bleak

Installation

pip install bleak-pythonista

Usage

Direct import

import asyncio
from bleak_pythonista import BleakScanner, BleakClient

async def main():
    devices = await BleakScanner.discover(
        service_uuids=["<some-service-uuid>"]  # optional
    )
    for d in devices:
        print(d)        
        client = BleakClient(d)
        await client.connect()
        print(client.services)
    
asyncio.run(main())

With bleak itself

import asyncio
from bleak import BleakScanner, BleakClient
from bleak_pythonista import BleakScannerPythonistaCB, BleakClientPythonistaCB

async def main():
    devices = await BleakScanner.discover(
        service_uuids=["<some-service-uuid>"],  # optional
        backend=BleakScannerPythonistaCB,
    )
    for d in devices:
        print(d)        
        client = BleakClient(d, backend=BleakClientPythonistaCB)
        await client.connect()
        print(client.services)
    
asyncio.run(main())

[!WARNING] DO NOT NAME YOUR SCRIPT bleak.py or bleak_pythonista! It will cause a circular import error.
