LEAPS Gateway

LEAPS Gateway serves as a bridge between the UWB and the TCP/IP networks.

Key Features

  • The LEAPS Gateway communicates on one side with the LEAPS UWBS via the generic LEAPS API, SPI, or USB and on the other side with the LEAPS Server via the TCP/IP.

  • Depending on the LEAPS UWB networking profile, it provides a medium for transferring the uplink and downlink location and telemetry data of the Anchors and Tags to and from the MQTT Broker.

  • The interconnection with the UWBS is done via the SPI on a dedicated LEAPS Gateway embedded device. When the interconnection with the LEAPS UWBS is done via the USB, like in the case of the UDK1 devices, LEAPS Gateway runs on a Linux platform as a daemon service.

Installation

System Requirements

Docker’s system requirements vary based on the operating system.

  • For Linux, you need a 64-bit architecture, a compatible kernel version, and specific kernel features.

  • On Windows, use Docker Desktop on Windows 10 with virtualization enabled.

  • On macOS, use Docker Desktop with macOS 10.13 or newer. In terms of hardware, a minimum of 2GB RAM is recommended, along with sufficient CPU and disk space.

Note

Refer to Docker official documentation for up-to-date details.

Instructions

  1. Install Docker on your PC

Install Docker Desktop on Linux

Additionally, you can refer to the following commands to install:

curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh ./get-docker.sh
sudo usermod -aG docker $USER

Install Docker Desktop on Windows

  1. Create folder leaps_gateway_hub and subfolder data. Then, add the leaps-gateway.conf configuration file in leaps_gateway_hub/data.

  1. Open a command prompt or terminal window on your PC.

  • Navigate to the folder where you created the configuration file.

For example, on Ubuntu (Linux):

cd leaps_gateway_hub/

  1. Install the LEAPS Gateway Docker packages, run:

Note

LEAPS Gateway requires the use of a USB port. Therefore, users need to run with admin rights to mount and use USB on the docker container.

sudo docker run -d -it --name some_name --privileged -v /dev/bus/usb:/dev/bus/usb -v /path/to/data/data/:/app/data/ leapslabs/leaps_gateway:tag /app/leaps_gateway --cfg /app/data/leaps_gateway.conf

Where some_name is the name you want to assign to your container, and the tag specifies the leaps-gateway version you want.

  • Recommended run options

    • --user $(id -u):$(id -g) Run the instance under a specific user and group.

    • --restart unless-stopped Restart automatically the instance in case the server would crash.

  1. The LEAPS Gateway installation process will begin.

For example, on Ubuntu (Linux):

sudo docker run -d -it --name leaps_gateway --privileged -v /dev/bus/usb:/dev/bus/usb -v "$(pwd)"/data/:/app/data leapslabs/leaps_gateway:latest /app/leaps-gateway -c /app/data/leaps-gateway.conf

  1. Verify that the installation is successful, run:

For example, on Ubuntu (Linux):

sudo docker ps

CONTAINER ID   IMAGE                    COMMAND                  CREATED          STATUS                          PORTS     NAMES
