i can use a bluetooth device and any python module with Flet?

[9acca9]

Hi, sorry the dumb question. I just hear about Flet.
I want to make a device that is pair with a android cellphone. Recieve a variable string from that device in the app, and use Python-Chess (https://python-chess.readthedocs.io/en/latest/) module to interpret, later send that value to lichess api (Berserk module)

The thing is i have a limitation in which modules i could use?
Thanks!

Hello, I don't know if you still have the question but I also had that problem but no Python module is directly compatible with the use of Bluetooth on cell phones so you can use low-process commands. I'll leave you my code if it helps you. import subprocess
import os
import flet
from flet import *

def main(page: Page):
page.title = "Bluetooth File Sender"

you_file = TextField(label="Your file name")
destination_mac = TextField(label="MAC Address")
scan_result = Text(weight="bold")

def scan_devices(e=None):
    try:
        res = subprocess.check_output(["hcitool", "scan"]).decode("utf-8")
        print(res)

        devices = [line.split("\t", maxsplit=1) for line in res.splitlines()[1:]]
        formatted_devices = [
            f"MAC Address: {mac} \t Device: {name}" for mac, name in devices
        ]
        scan_result.value = "\n".join(formatted_devices)
        page.update()

    except Exception as e:
        scan_result.value = f"Error scanning: {str(e)}"
        page.update()

def send_file_now(e):
    command = f"bluetooth-sendto --device={destination_mac.value} {you_file.value}"
    result = os.system(command)
    if result == 0:
        print("Success! Transfer complete.")
        page.snack_bar = SnackBar(
            Text("Success sending!!", size=10),
            bgcolor="blue"
        )
        page.snack_bar.open = True
        page.update()
    else:
        print("Failed to send file.")
        page.snack_bar = SnackBar(
            Text("Failed to send file!", size=10),
            bgcolor="red"
        )
        page.snack_bar.open = True
        page.update()

page.add(
    Column([
        Text("Upload file to Bluetooth", size=25, weight="bold"),
        you_file,
        destination_mac,
        ElevatedButton("Scan Devices", bgcolor="gray", color="white", on_click=scan_devices),
        scan_result,
        ElevatedButton("Send Now", bgcolor="blue", color="white", on_click=send_file_now)
    ])
)

flet.app(target=main)
