Hey guys, I’m trying to get Bluez to work with my resinio with a Python3 app ; I can’t get Bluez 5.23 to work so i have hope using later versions (5.48) which is only available in the Stretch repos. I’m using the resin/raspberrypi3-python:3 image which is based on Raspbian Jessie. Is there a way to have a Python Docker image that uses Raspbian Stretch ? I’ve tried to use resin/raspeberrypi3-debian:stretch and install Python3 inside, but I get weird errors with resin (Failed to install release agent and a bunch of other stuff) and my python local import won’t work when they do work with the proper docker image.
Thanks for the help,
Alex
hey @Shad , that is very strange. Do you install python3 in the debian stretch image? also could you post your Dockerfile here where you get the strange errors and we can try figure out what is going on. I would expect it to work fairly easily.
Here’s the DockerFile :
FROM resin/%%RESIN_MACHINE_NAME%%-debian:stretch
WORKDIR /usr/src/app
ENV INITSYSTEM on
COPY ./requirements.txt ./requirements.txt
RUN apt-get update && apt-get install -y \
hostapd dhcpcd5 dnsmasq \
darkice icecast2 curl haveged rfkill \
pulseaudio pulseaudio-module-bluetooth bluez bluez-firmware vlc\
libdbus-1-dev libglib2.0-dev libudev-dev libical-dev libreadline-dev\
python3 python3-dev python3-pip python3-setuptools python3-wheel\
&& adduser --disabled-password --gecos "" ices\
&& adduser ices pulse-access \
&& mkdir /usr/local/icecast \
&& mkdir /usr/local/icecast/logs \

&& pip3 install -r ./requirements.txt \
&& bluetoothctl --version
COPY . ./
ENV INITSYSTEM on
CMD ["python3", "Octave/main.py"]
and here are the logs:

I still could log in the docker, BlueZ version was as expected 5.43 but i couldn’t use it, here are the bluetoothd service logs:

I don’t know if its related to resin’s release agent, but at least with BlueZ 5.23 on Raspbian Jessie i could get an adapter and try to do things with bluetoothctl, even if it would ignore the /etc/bluetooth/main.conf file.
I hope this helps,
Hi,
I’m pretty sure that all these warnings are not related as they complains about some masked services.They were masked in purpose since we don’t want them to run in the container.

the local import issue seems weird, let me try to replicate it.
