Pybrics hub-to-hub communication test

This is the simple test for broadcast communication between to Technic Hubs (you can change it to City Hub Essential Hub, Inventor Hub, or Prime Hub).

Steps:

1. Install experimental firmware for your hubs following this guide
2. Connect sender hub and run this code:

from pybricks.hubs import TechnicHub
from pybricks.tools import wait
from pybricks.parameters import Color
from pybricks.experimental import Broadcast

hub = TechnicHub()
radio = Broadcast(topics=["tilt"])
while True:
    pitch, roll = hub.imu.tilt()
    hub.light.on(Color(roll+180))
    radio.send("tilt", (pitch,roll))
    wait(10)

3. Connect reeiver hub and run this code:

from pybricks.hubs import TechnicHub
from pybricks.tools import wait
from pybricks.parameters import Color
from pybricks.experimental import Broadcast

hub = TechnicHub()
radio = Broadcast(topics=["tilt"])
while True:
    data = radio.receive("tilt")
    if data:
        pitch, roll = data
        hub.light.on(Color(roll+180))
    wait(10)

And you are done:

receiver.py

from pybricks.hubs import TechnicHub
from pybricks.tools import wait
from pybricks.parameters import Color
from pybricks.experimental import Broadcast

hub = TechnicHub()
radio = Broadcast(topics=["tilt"])
while True:
    data = radio.receive("tilt")
    if data:
        pitch, roll = data
        hub.light.on(Color(roll+180))
    wait(10)

sender.py

from pybricks.hubs import TechnicHub
from pybricks.tools import wait
from pybricks.parameters import Color
from pybricks.experimental import Broadcast

hub = TechnicHub()
radio = Broadcast(topics=["tilt"])
while True:
    pitch, roll = hub.imu.tilt()
    hub.light.on(Color(roll+180))
    radio.send("tilt", (pitch,roll))
    wait(10)
