HUB TO HUB INVENTOR HUB

[DexterTaha]

I USE TO HUB OF InventorHub TO CUMMINICATE WICH EACH OTHER ON SENSE THE BUTTONS AND THE OTHER HAVE A CONDITION TO A THING IN THE OTHER HUB WHEN FIRST HUB IS CLICKED

Remote Hub:

from pybricks.hubs import InventorHub
from pybricks.parameters import Button, Icon
from pybricks.tools import wait

hub = InventorHub(broadcast_channel=1, observe_channels=None)

while True:
    pressed = hub.buttons.pressed()
    if any(pressed):
        if Button.LEFT in pressed:
            hub.ble.broadcast(1)  # Send a signal for left arrow
        elif Button.RIGHT in pressed:
            hub.ble.broadcast(2)  # Send a signal for right arrow
        elif Button.CENTER in pressed:
            hub.ble.broadcast(3)  # Send a signal for up arrow

    wait(10)

Vehicle Hub:

from pybricks.hubs import InventorHub
from pybricks.parameters import Button, Icon
from pybricks.tools import wait

hub = InventorHub(broadcast_channel=None, observe_channels=[1])

while True:
    data = hub.ble.observe(1)  # Listen for signals from the remote hub
    if data is not None:
        if data == 1:
            hub.display.icon(Icon.ARROW_LEFT_DOWN)
        elif data == 2:
            hub.display.icon(Icon.ARROW_RIGHT_DOWN)
        elif data == 3:
            hub.display.icon(Icon.ARROW_UP)

    wait(10)

THIS MAY TWO CODES BUT IT DID WORK AND I DONT KNOW WHY

I tested your programs and both have a syntax error:

 File "issue_1625_vehiclehub.py", line 8, in <module>
TypeError: can't convert NoneType to int
Traceback (most recent call last):
  File "issue_1625_remotehub.py", line 8, in <module>
TypeError: object of type 'NoneType' has no len()

I run with firmware version 3.5.0 on beta.pybricks.com

Remove the

 , observe_channels=None

and

 broadcast_channel=None, 

and retry.

Remember if you press the center button that hub will stop running.

Thanks, it is working now.
Is there a way for me to develop a code for hubs that send and receive data from each other?

[BertLindeman]

In fact you just did that 😄

Maybe have a look at a hub to hub tutorial
