This repository contains the Protocol Translator examples for the Edge.

Pt-example is a basic example of the C-API and pt-client usage.

mqttpt-example is an example of a protocol translator that connects to endpoints using MQTT. It can be used without real MQTT hardware using provided Mosquitto MQTT simulator scripts. The endpoints may publish for example temperature and humidity values to Device Management.

NOTE! This requires Eclipse's Mosquitto - see installation info: https://mosquitto.org/download/

The blept-example is a protocol translator reference implementation for use with Bluetooth Low Energy (BLE) devices that implement a Bluetooth Low Energy Generic Attributes (GATT) server. It connects to BLE devices and translates their GATT services and characteristics into Open Mobile Alliance (OMA) Lightweight Machine to Machine (LwM2M) Objects and Resources.

The simple-js-examples are different from the rest of the examples. Instead of using the provided pt-client library these examples use Edge Core protocol translator and management API directly.

These are examples on how a protocol translator or management API application can be created using Javascript. See the simple-js-examples/README.md for instructions.

This example tests the robustness and thread safeness of Protocol API C-API interface

1. Directly on Ubuntu 22.04 or 20.04 or
2. Using Docker.

1. Dependencies

   Following dependencies are needed in the build system.

   • librt
   • libstdc++
   • OPTIONAL for mqttpt-example: libmosquitto

   Install these (using sudo typically):

   sudo apt-get update
   sudo apt-get install build-essential cmake git libc6-dev \
      libmosquitto-dev mosquitto-clients libglib2.0-dev \
      doxygen
   

   NOTE! Mosquitto might not be available directly in your distribution (for example Ubuntu 22.04), see https://mosquitto.org/download/ for more installation information.

2. Preparing all the sources

   Please run the following to clone and update all the git modules.

   git submodule update --init --recursive
   

3. Building

   Makefile has options to build any of the pt-examples separately, or all at the same.

   To make all examples without debug information and with default trace level, run

   make build-all-examples
   

   It will build the examples to build/bin directory.

   To make all examples with debug information and debug trace level, run

   make build-all-examples-debug
   

   It will build the examples to build-debug/bin directory.

   To make all examples with ThreadSanitizer and debug trace level, run

   make build-all-examples-sanitize
   

   It will build the examples to build-sanitize/bin directory.

   Running make all will generate build, build-debug and build-sanitize directories.

   Please note following: mqttpt-example will not be built if the libmosquitto is not installed.

   For more examples, see the rules in the Makefile.

4. Running the examples

   Each of the examples has a README.md file that documents how to run the example.

Before building the docker image, fetch the dependencies:

git submodule update --init --recursive

Build:

docker build -t pt-example:latest -f ./Dockerfile.pt-example .

Run:

docker run -v /tmp:/tmp pt-example:latest

Build:

docker build -t simple-pt-example:latest -f ./Dockerfile.simple-pt-example .

Run in interactive mode:

docker run -v /tmp:/tmp -it simple-pt-example:latest
