Python drone connection Tmotor F7(Betaflight STM32F7x2)

[YY-71]

Hello everyone,

I am doing a project to connect drone with microcontroller Betaflight STM32F7x2 with python code. After some trials, I succeed detect the serial port with STM but it failed to connect like normal. My target is simple, to connect the STM, get battery value and simple motor activation.

I have tried with dronekit library, but the error showed as line below
class Parameters(collections.MutableMapping, HasObservers):
^^^^^^^^^^^^^^^^^^^^^^^^^^
AttributeError: module 'collections' has no attribute 'MutableMapping'
-------------ori code----------
from dronekit import connect
vehicle = connect('COM6', wait_ready=True)
print("Mode: %s" % vehicle.mode.name)

Besides, I have tried also with pymavlink, the error is different:
Serial port COM6 opened successfully.
Error establishing MAVLink connection: invalid literal for int() with base 10: 'COM6'
------------ori code-----------
import serial
from pymavlink import mavutil
def mavlink_connection(port, baudrate):
try:
connection = serial.Serial(port, baudrate)
# Create MAVLink connection
print(f"Serial port {port} opened successfully.")
mavlink_connection = mavutil.mavlink_connection('serial:' + port, baud=baudrate)
print("MAVLink connection established.")
return mavlink_connection
except Exception as e:
print(f"Error establishing MAVLink connection: {e}")
return None

if name == "main":
# Serial port settings
port = 'COM6'
baudrate = 115200
# Establish MAVLink connection
mavlink_conn = mavlink_connection(port, baudrate)
if mavlink_conn:
# Request heartbeat
mavlink_conn.mav.heartbeat_send(mavutil.mavlink.MAV_TYPE_GCS, mavutil.mavlink.MAV_AUTOPILOT_INVALID, 0, 0, 0)

Please comments if you any idea to solve it. Firstly for the connection. Thank you!

That's probably an old pipenv with new Python.
In any event, it's a Python issue.
