pybricksdev and pybricks on raspberry pi (connection ok, but nothing more)

[jajawunderbar]

Hi, i use a raspberry pi 5 with new version of pybricksdev an pybricks (installed with venv and pip). The connection is running, but i cant start a motor or read the tiltsensor. no errormessage. using thonny. Here a bit of code. Thanks! Mathias

import asyncio
from pybricksdev.connections.pybricks import PybricksHub
from pybricksdev.ble import find_device
from pybricks.pupdevices import Motor as HubMotor
from pybricks.parameters import Port
from time import sleep

async def control_hub_motor():
    hub = PybricksHub()
    device = await find_device('Pybricks Hub')
    await hub.connect(device)
    print("Technic Hub erfolgreich verbunden")
    hub_motor_a = HubMotor(Port.A)
    hub_motor_a.dc(50)
    sleep(1)
    hub_motor_a.stop()
    await hub.disconnect()
    print("Verbindung zum Hub getrennt.")

asyncio.run(control_hub_motor())

from pybricks.pupdevices import Motor as HubMotor
from pybricks.parameters import Port

print("Technic Hub erfolgreich verbunden")
hub_motor_a = HubMotor(Port.A)
hub_motor_a.dc(50)
sleep(1)
hub_motor_a.stop()

This needs to be placed in a separate .py file. Pybricks scripts run on the hub itself, not on the RPi.

Then use hub.run("/path/to/file.py") to run download and run the script on the hub.

sleep(1)

We don't have this in Pybricks. Use from pybricks.tools import wait instead.
