Hey @undera ,

I have troubles to get the demo.py example from your repo to work always. It worked multiple times (3-4 times), but most of the time the hub switches off WARNING:hub:Hub switches off, before an action can be started and the program stuck on that state. The bot turns off after 10 seconds of not interaction which is the default as far as I can tell. I've tried it on my mac, but no bluetooth backend seems to support MacOS so not test possible. For me it looks like the program on the pi is so slow (maybe wait for an event) and reach timeout before.

Hardware: raspberry pi 3 B, Lego Boost Robot
python: 3.7.3
virtual env: yes, with python3 -m venv
Bluetooth backend: bluepy 1.3.0
Firmware-Version: 2.0.00.0017

Here is the application stdout from demo.py. It extremely fast found the hub but it stuck on the line INFO:hub:Attached peripheral: LEDRGB on port 0x32 for some time, so it seems that the program is waiting for something here.

Maybe you have an idea how I can debug that problem.

Greetings

The proper way to troubleshoot this is to enable DEBUG level logging in demo.py (instead of INFO). Then run it again and share the log.

So it looks like there is indeed something that makes pylgbst to not receive any incoming messages from BLE after LEDRGB attach message. The library is helpless here, since it simply does not get any communication from underlying BLE stack.
This can be either hardware problem, or underlying library problem, bluepy in your case.

I would give a try to another connection library, for example pygatt. Again, I don't see anything that would cause such a pause on the library side (I can be wrong, though, since I did not write that part of library).

I tried every other backend, but non of them work. Always with the following error (here for gatt), seems like a different kind f problem here.

I also used gattctl --discover and get following message

See also: https://github.com/getsenic/gatt-python#installing-gatt-sdk-for-python

So I run sudo apt-get install python3-dbus but it's already installed.

I checked it also on another raspberry pi, same issue there.

I also tried your bleak-troubleshooting #70 branch with following log

Do you have bluez installed? It is installed with sudo apt-get install bluez

/home/pi/lego/env/lib - are you using some sort of virtualenv? If yes, then you need to install python dbus lib into that virtual env (pip install dbus-python or so, might also need some libs, see https://stackoverflow.com/questions/13365697/install-python-dbus-in-virtualenv), or use system-site-packages option of it.

installing dbus-python via pip install dbus-python does not work for gatt, but it worked for bleak. With bleak it works most of the time. The strange thing is that I can not really find out under which conditions it does not work (I also check the bluetooth distance, but it did not change that much).

Hi, i was struggling with rpi and my lego boost. thanks to this issue i got the demo.py running within docker on rpi3. maybe you can make use of it: https://gitlab.com/tigabeatz/rpi-docker-lego

i needed

RUN pip3 install bluepy pylgbst dbus-python gatt gobject PyGObject \
 && git clone https://github.com/undera/pylgbst.git

and

RUN apt-get update && apt-get install -y \
    build-essential git wget make libical-dev libdbus-1-dev libglib2.0-dev libreadline-dev libudev-dev systemd pkg-config libcairo2-dev gcc python3-dev libgirepository1.0-dev

to run the demo.py i start it with gatt and the boosts mac, otherwise i do not get connections:

mh=$(timeout -s INT 10s hcitool lescan | grep 'Move Hub')
mhmac=$(echo $mh | tr -d ' Move Hub')
python3 /usr/src/app/pylgbst/examples/demo.py -c "gatt://${mhmac}"
