dbus[70]: arguments to dbus_connection_get_object_path_data() were incorrect

[Sjeff]

Running Intel NUC Docker Configuration.

After i updated to latest beta i receive the following error.

Looks like everything is working as is should be.
Thought i would be good to report this error anyway.

dbus[70]: arguments to dbus_connection_get_object_path_data() were incorrect, assertion "connection != NULL" failed in file ../../../dbus/dbus-connection.c line 5904.

This is normally a bug in some application using the D-Bus library.

   D-Bus not built with -rdynamic so unable to print a backtrace

Appreciate the report, but since docker isn't the default method for running this script (although it may be in the future), I'll go ahead and close this. Please follow up if you notice anything negative happening.

Thanks!

i know that this issue is closed but i managed to fix the bluetooth problem under docker.

i'm using

• Intel NUC NUC7CJYH
• Debian stretch with kernel 4.19.0-0.bpo.1-amd64
• docker v.18.09.1, build 4c52b90

i managed to create an image using this Docker file:

FROM debian:stretch-slim

RUN set -x && \
    apt-get update && \
    apt-get install -y  --no-install-recommends \
        bash \
        bc \
        bluez \
        bluez-hcidump \
        bluetooth \
#        usbutils \ #if you are using an external usb stick
        ca-certificates \
        curl \
        git \
        mosquitto-clients

RUN mkdir /monitor && \
    git clone https://github.com/andrewjfreyer/monitor.git /monitor

VOLUME ["/monitor", "/config"]

# Set up the entry point script and default command
COPY run.sh /
RUN chmod +x /run.sh
ENTRYPOINT ["/run.sh"]

WORKDIR /monitor

CMD ["/bin/bash", "monitor.sh", "-D", "/config"]

the run.sh file

#!/bin/bash
set -e

# inspired from https://github.com/moby/moby/issues/16208#issuecomment-161770118
service dbus start
service bluetooth start
hciconfig hci0 up

exec "$@"

my docker-compose.

version: '3'

services:
  monitor.sh:
    build:
      context: /PATH/TO/YOUR/DOCKERFILE
    image: hatemzidi/monitor.sh:v0.1.981
    container_name: monitor.sh-test
    restart: always
    volumes:
      - /etc/localtime:/etc/localtime:ro
      - /srv/monitor/config:/config
    network_mode: host
    privileged: true
    command: bash monitor.sh -x -a -D /config

just run docker-compose up, configure your monitor properly and rerun it.
et voilà :)

[andrewjfreyer]

Thanks for the follow-up!

[Sjeff]

@hatemzidi do you have a working dockerfile with mosquitto 1.5+ for the latest monitor update?

[hatemzidi]

@Sjeff since i'm using mosquitto with other services, i just added it in my docker-compose as a separate service and linked monitor with mosquitto.

[Sjeff]

@hatemzidi can you share the docker-compose file?
i'm running mosquitto in a separate container already.

[hatemzidi]

@Sjeff
here is a snippet of my docker-compose

version: '3'

services:
#[...]
  monitor.sh:
    image: hatemzidi/monitor.sh:v0.2.053
    container_name: monitor.sh
    restart: always
    network_mode: host
    volumes:
      - /dev/bus/usb:/dev/bus/usb
      - /run/dbus:/run/dbus
      - /etc/localtime:/etc/localtime:ro
      - ./config/monitor:/config
    privileged: true
    cap_add:
      - NET_ADMIN
    command: bash monitor.sh -x -a -D /config

  mosquitto:
    container_name: mosquitto
    image: eclipse-mosquitto:latest
    ports:
      - "1883:1883/tcp"
    restart: unless-stopped
    volumes:
      - /etc/localtime:/etc/localtime:ro
      - ./config/mosquitto/settings:/mosquitto/config
      - mosquitto-data:/mosquitto/data

#[...]

since monitor is in host mode, i call the mosquitto using the loopback (localhost:1883)

ps: my images aren't shared yet on docker hub.

[Sjeff]

Thanks @hatemzidi compose file is kinda similar to mine.

When updating to latest version 0.2.068 we need mosquitto_pub and mosquitto_sub version 1.5+.
its seems there is no mosquitto-clients package version 1.5+ yet.

[hatemzidi]

@Sjeff i just verified my mosquitto image and it’s v1.5.8
my monitor image seems to work flowlessly... except some bluetooth bugs for the moment.

preference: using default mqtt protocol version

did you force the version in your preferences ?

mqtt_version='mqttv311'

[Sjeff]

Here are the mosquitto_preferences:
I use a username and password.

same error occurse when i use

mqtt_version='mqttv311'

@Sjeff
could you please check this ?

dpkg -s mosquitto-clients | grep '^Version:'

i have a feeling that this package isn't updated.

[Sjeff]

From inside the monitor container.

pi@raspberrypi:/srv/docker/monitor $ docker exec -it monitor /bin/bash
root@raspberrypi:/monitor# dpkg -s mosquitto-clients | grep '^Version:'
