Examples and information about integrating ROS with AWS IoT using the mqtt_bridge package.

aws-iot-bridge-example's Issues

binary install via `apt` installs wrong package?

Hi, when I run binary installation procedure as described in README like

sudo apt-get update
sudo apt-get install -y ros-kinetic-iot-bridge

I get the package below installed. I don't think this is the right package.
http://wiki.ros.org/iot_bridge

My env:

• ROS Kinetic
• Ubuntu 16.04 on Raspberry Pi 3B+
• The OS image I am using the below. This is the robot vendor based image but /etc/apt/sources.list.d includes ros-latest.list which points http://packages.ros.org/ros/ubuntu
  • https://downloads.ubiquityrobotics.com/pi.html

[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed

Hi,

I am trying to connect a ROS device to AWS IoT Core, I have followed the docs:

• Create a Thing
• Register a Device
• Configure Your Device

I created and downloaded the certificates, the mqtt_bridge package is working well, and finally I have made the changes in:

aws_iot_params.yaml

tls:
  ca_certs: certs/amazonRootCA1.pem
  certfile: certs/certificate.pem
  keyfile: certs/private.pem
connection:
  host: ENDPOINT.iot.us-east-1.amazonaws.com

And aws_iot_bridge.launch

<rosparam param="mqtt/tls/ca_certs" subst_value="true">$(find aws_iot_mqtt_bridge)/config/certs/amazonRootCA1.pem</rosparam>
<rosparam param="mqtt/tls/certfile" subst_value="true">$(find aws_iot_mqtt_bridge)/config/certs/certificate.pem</rosparam>
<rosparam param="mqtt/tls/keyfile" subst_value="true">$(find aws_iot_mqtt_bridge)/config/certs/private.pem</rosparam>

The amazonRootCA1.pem file has this data and the ENDPOINT information comes from the output of aws iot describe endpoint (AWS CLI)

Finally, here is my file tree

Can not run the bridge 'SyntaxError: invalid syntax'

A reproducible test case or series of steps:
Here is my Docker file:

  # Update apt-get because its cache is always cleared after installs to keep image size down

# copy the launch file
COPY aws_iot_bridge.launch $CATKIN_WS/src/aws-iot-bridge-example/aws_iot_mqtt_bridge/launch/aws_iot_bridge.launch

# open up the bash script for interactivity
CMD ["bash"]

In terms of how I ran the program, here are my steps

1. In the terminal, source your workspace `source ../devel/setup.bash`
2. Run `cd ~/catkin_ws/src/aws-iot-bridge-example/aws_iot_mqtt_bridge`
3. Run `roslaunch aws_iot_mqtt_bridge aws_iot_bridge.launch bridge_params:=config/aws_iot_params.yaml`

I have tested out all of the AWS IoT connections / policies / certs etc. outside of ROS and have validated that they work.
I expect that with my configurations, this package should work as well when I run the roslaunch; however, instead I get this result:

[HELP!]can get mqtt msg from aws iot but could not get in rostopic

ubuntu 16.04
kinetic

every time, when I start the demo.launch
the output log will be like this.

I do the test
OK local ros->aws iot as mqtt message
Failed aws iot mqtt message->local ros message
also I listen the 8883 port and could get the message from aws iot test client.

then I find that if I comment the part for mqtt to ros bridge like this.

the disconnected log will disappear.

what is the problem here?

does anyone fall into the same situation as mine?
