Hello,

I'm having currently issues while installing mqtt_bridge... Following the readme, I installed all dependencies referred, but after downloading the folder and running:

roslaunch mqtt_bridge demo.launch

I get the following output: [demo.launch] is neither a launch file in package [mqtt_bridge] nor is [mqtt_bridge] a launch file name

Can anyone help on this?

Best regards, BV

I am getting something similar. Following the same procedure as @1140464BV , but I get

Traceback (most recent call last): File "/home/pi/catkin_workspace/src/mqtt_bridge/scripts/mqtt_bridge_node.py", line 5, in from mqtt_bridge.app import mqtt_bridge_node ImportError: No module named mqtt_bridge.app

Any tips?

I got the same error on Ubuntu 16.04 and kinetic when trying to install from my workspace.

I got it working with installing the system package instead:

sudo apt install ros-kinetic-mqtt-bridge

This works for me (after removing bson which I installed via pip).

After installing a package, you must add it to your environment. In the /install and /devel folders there is a "setup.bash" file. You need to add one of these by writing it's path at the bottom of ~/.bashrc

After installing the dependencies, first you have to build mqtt_bridge using catkin_make, then you have to source the environment variables.

cd into mqtt_bridge directory and type the following commands. catkin_make source devel/setup.bash
