Hey! Could you assist please with installation, I keep getting these. Tried to reinstall everything I knew.

I'm from Java and quite newbie with python env

ego-hub-tk git:(main) ✗ python3 run_command.py

➜  lego-hub-tk git:(main) ✗

Hello.

I am having trouble establishing an link for upstream/downstream data link. Could you please elaborate, perhaps with some examples, how to establish a 2-way data link between HUB <-> PC or is that something that is not possible with this tool?

The only option that I see, is possibility of activating different slots, but we can not call a function with variables passed down within a program, on a slot - am I correct?

I was playing around with this today and got

WARNING:data.HubMonitor:unhandled message: {'m': 14, 'p': 0}
WARNING:data.HubMonitor:unhandled message: {'m': 14, 'p': 5}
WARNING:data.HubMonitor:unhandled message: {'m': 14, 'p': 1}

WARNING:data.HubMonitor:unhandled message: {'m': 14, 'p': 1}
WARNING:data.HubMonitor:unhandled message: {'m': 14, 'p': 0}

Any ideas?

Document a sample code for getting Hub's Gyro readings from python shell.

First of all, thanks for your effort to allow programming the Lego Hub on Linux!

This is what happens when I run python3 run_command.py ls:

$ python3 run_command.py ls
Traceback (most recent call last):

I have installed the prerequisites via pip3 install -r requirements.txt before running run_command.py ls.
I am quite new to Python and pip, maybe I am missing something basic.

I am on Fedora 34.

Hello. On windows it may ask you permission for USB com's.

It can happen when something is already using HUB while you are trying to connect to it. To fix the problem, stop other programs from using HUB when you are trying to connect.

It seems like basic knowledge to the knowledgeable, but maybe a hit printed somewhere on these lines could be useful.

Hello. I am trying to access print("test") being called in a function running on HUB. But I can only receive ERROR level messages (probably not coming from something_changed). However when running toolkit tools like hubcontrol.py I see that "test" gets printed on INFO level. How to access INFO level from monitor event console_print ?

start_monitoring_on_pc.py

import time

from data.HubMonitor import HubMonitor
from comm.HubClient import HubClient, ConnectionState

connection = 0


class Main:
    client = HubClient()
    hm = HubMonitor(client)

    def __init__(self):
        self.hm.events.console_print += self._console_print
        self.client.start()

    def _console_print(self, msg):
        print(msg)


Main()


def send_heartbeat_to_backend(connection):
    # TODO
    if connection == 0:
        print('HUB is offline')
    elif connection == 1:
        print('Connection established to HUB')
    elif connection == 2:
        if not Main.hm.execution_status[1]:
            print('Main program started on HUB')
        if Main.hm.execution_status[1]:
            print('Main program running')


def send_cube_map_to_backend(map):
    # TODO
    print(map)


while True:
    send_heartbeat_to_backend(connection)
    time.sleep(1)
    if Main.hm.connection_state == ConnectionState.TELEMETRY:
        if connection == 0:
            connection = 1
        elif connection == 1:
            Main.client.program_execute(1)
            connection = 2
    else:
        print('waiting...')

EDIT:
I noticed your commit... d3b8684 after re-adding these lines I got it working as intended. Please update the docs that by default, these events do no fire, instead they are being logged to file (which I saw actually) but I could not find the root cause for it. That - or better yet, make it optional to log to console or file or both. 👍

Hi,

I am the maintainer of sharpbrick/powered-up which is a .NET library for communicating with the Lego Technic Powered Up hubs. In that world, I am used to write software on a PC/Mac/Linux device and instruct the hub what to do. I worked hard with the LWP2 spec and collaborated in the community to get the best experience out of it.

So the question to the Spike/Mindstorm Hub experts: Is the remote protocol of the mindstorms hub a debugging protocol (aka receiving telemetry and messing with the execution of a previous transferred python program) OR is it a true remote control protocol where commands are sent by a controlling PC and then executed by the hub?

I have not found a lot of documentation, so i am bit confused? Also there is a mystical hub to hub protocol which I also found no real information about it.
