Multiple devices and knowing from which device notifications originate from

[hbldh]

This is a simple example of how one can use functools.partial to have notification callbacks with access to the device they came from:

from Bleak import BleakClient

def my_notification_callback_with_client_input(
    client: BleakClient, sender: int, data: bytearray
):
    """Notification callback with client awareness"""
    print(
        f"Notification from device with address {client.address} and characteristic with handle {client.services.get_characteristic(sender)}. Data: {data}"
    )

Write your Bleak application and when you call start_nofify, then use functools.partial to inject the client object into the function:

from functools import partial

# [...]

client.start_notify(
    char_specifier, partial(my_notification_callback_with_client_input, client)
)

Thanks sir, I'll give it a try.

Great, I am able to see the data from different devices simultaneously with the address of the modules.
