TypeError when going from bleak to bleekWare #5
Description
Hi,
I've created a very simple app that connects to a device and print whatever the device is sending.
The app works well in Linux using bleak, but when I compile it for Android using bleekWare, it connects ok but when it should print on screen what it receives, it prints TypeError: 'bool' object is not callable
Here's the script Im using:
import asyncio
import toga
from toga import App, Button, Label, Box
if toga.platform.current_platform == 'android':
from .bleekWare import bleekWareError as BLEError
from .bleekWare.Client import Client as Client
from .bleekWare.Scanner import Scanner as Scanner
else:
from bleak import BleakError as BLEError
from bleak import BleakClient as Client
from bleak import BleakScanner as Scanner
# UUIDs for the UART service and characteristic
UART_SERVICE_UUID = "6E400001-B5A3-F393-E0A9-E50E24DCCA9E"
UART_TX_UUID = "6E400003-B5A3-F393-E0A9-E50E24DCCA9E"
class HelloWorld(App):
def startup(self):
self.label = Label("Waiting for data...")
self.button = Button("Connect", on_press=self.connect)
self.box = Box(children=[self.label, self.button])
self.main_window = toga.MainWindow(title='BLE UART')
self.main_window.content = self.box
self.main_window.show()
async def connect_to_device(self):
device_address = "2C:CF:67:97:DE:C7"
try:
async with Client(device_address) as client:
if client.is_connected():
await client.start_notify(UART_TX_UUID, self.notification_handler)
self.label.text = "Connected! Waiting for data..."
# Keep the connection alive
while True:
await asyncio.sleep(1)
except Exception as e:
self.label.text = f"Error: {e}"
def notification_handler(self, sender, data):
# Handle incoming data from the Bluetooth device
message = data.decode('utf-8')
self.label.text = f"Received: {message}"
def connect(self, widget):
# Schedule the async connection task in the event loop
asyncio.create_task(self.connect_to_device())
def main():
return HelloWorld()
Any idea why this happens?
Thank you
