rovercontrol

A simple tkinter python app to control APP4MC rovers via HONO using AMQPS.

Requirements

Requires python3 to run.

See requirements.txt for python library dependencies. The requirements should be satisfied by the installation steps below.

Installation

• Install TK for Python 3 using sudo apt install python3-tk (or similar commands on non-Debian/Ubuntu systems)
• Install cli-proton-python using sudo pip3 install cli-proton-python
• If you get SSL errors when running the script, rebuild python-qpid-proton (used by cli-proton-python) with SSL support from OpenSSL. Building with OpenSSL requires python-pkgconfig to find OpenSSL - python-pkgconfig might be missing. Below script makes sure it is present.
  • Uninstall the packages without SSL first sudo pip3 uninstall python-qpid-proton cli-proton-python
  • Make sure python-pkgconfig is available: sudo apt install python-pkgconfig
  • Rebuild with verbose output: sudo pip3 -v install cli-proton-python should show Using openssl version 1.0.2n (found via pkg-config) if you still get Warning: OpenSSL not installed - disabling SSL support! SSL will keep failing.

Use

• Adapt the following constants in the Rover_Control.py script
  • password the password Hono's consumer@HONO user
  • hostAndPort the host name and the AMQPS port of the Hono dispatch router in the format <hostname>:<port>
  • tenant the Hono tenant that contains the rover to control
  • device the Hono device ID of the device to control
  • trustStore a trust store (i.e. a certificate) in PEM format that contains either the certificate presented by the host to connect to or the certificate of the CA that issued the certificate.
• Start using python3 Rover_Control.py
