Telemetry-UI Backend with Hono C&C

The backend establish a connection to Eclipse Hono for sending commands to according devices as well as consumes telemtry data from an InfluxDB to visualize them in the frontend.

Running Telemetry-UI Backend

Prerequisite

Tested on Ubuntu 18.04

Frameworks

Apache Maven (3.6.0)

sudo apt-get install maven

Configuration

To establish a connection to Eclipse Hono and InfluxDB, the application.properties at /src/main/resources/ have to be configured with the according IPs and credentials.

Starting the application

To run the application, enter the main folder and execute the following command:

mvn spring-boot:run

What you need to know about the Application

• Controller are the REST-API implementations which use services to implement business logic
• the package payload contains the needed classes to use as JSON packet for communication to frontend and other software
• application.properties is used to configure hono and influxdb

Implemented REST-API

GET METHOD - /telemetry

This interface allows applications to get the telemetry data from an InfluxDB as JSON.

POST METHOD - /command-control

This interface allows an application to move a rover by putting command and speed as JSON in a POST-Request.

Current Limitations

• modular implementation for the REST-API so that the frontend can decide which of the rover's data it wants or which rover it wants to control
• other use cases for the third-party backend for example integrating the appstore backend to this backend to make access consistent
