Which firmware is on your hub? Once you're connected, you can see it by clicking on the green battery indicator in the bottom right of the app.

Or if you got an automatic prompt to update, make sure that you do :)

Hi Laurens, thank you for your answer. The firmware version is 4.01. Michel Le mer. 24 juin 2026 à 15:36, Laurens Valk ***@***.***> a écrit :

The script you shared is working for me:

from pybricks.messaging import BLERadio

# Initialize the hub.
radio = BLERadio(broadcast_channel=1)

What error do you see? Or maybe the error was from before you updated and it is actually working now?

That is not the same script, judging by the line numbers. Please share exactly what you have tried and doesn't work.

We can help better with more details :-)

Hi, what do you mean by "maybe the error was from before you updated and it is actually working now?" I copy exactly your example from pybricks.pupdevices import Motor from pybricks.parameters import Port from pybricks.tools import wait from pybricks.messaging import BLERadio # Initialize the hub. radio = BLERadio(broadcast_channel=1) # Initialize the motors. left_motor = Motor(Port.A) right_motor = Motor(Port.B) while True: # Read the motor angles to be sent to the other hub. left_angle = left_motor.angle() right_angle = right_motor.angle() # Set the broadcast data and start broadcasting if not already doing so. data = (left_angle, right_angle) radio.broadcast(data) # Broadcasts are only sent every 100 milliseconds, so there is no reason # to call the broadcast() method more often than that. wait(100) the result is Traceback (most recent call last): File "testbl.py", line 4, in <module> ImportError: no module named 'pybricks.messaging' Michel Le jeu. 25 juin 2026 à 09:14, Laurens Valk ***@***.***> a écrit :

Could you please try running the following and report back what you see?

from pybricks import version
print(version)

from pybricks.messaging import BLERadio

radio = BLERadio(broadcast_channel=1)

[BertLindeman]

Michel, what type of hub do you run this script?

Bert

[laurensvalk]

@BertLindeman - the version script above should show.

[BertLindeman]

@BertLindeman - the version script above should show.

Correct.
Michel I ran this on my primehub Laurens program and added a print so we see that there was no erroe:

from pybricks import version
print(version)

from pybricks.messaging import BLERadio

radio = BLERadio(broadcast_channel=1)
print(radio)

I get:

('primehub', '4.0.1', 'ci-release-101-v4.0.1 on 2026-06-24')
<BLERadio>

What is your output?

Bert

Right, that means your firmware hasn't been updated yet on this hub. Just update the firmware, and you'll get 4.0.1 with the updated messaging module. :)

Isn't there a notification every time you connect that you should consider updating to use all features?
