LEAPS Raspberry Pi

This page provides:

  • The LEAPS Raspberry Pi package.

  • Information about system requirements.

  • Instructions on how to install LEAPS Raspberry Pi.

The installation is fast and easy and only needs to be done once.

Before starting: Remember to back up any important files from the SD card you want to keep, as all data will be permanently overwritten during formatting.

System requirements

  • Raspberry Pi 3B or newer.

  • Recommended: A set of UDK1 (At least five devices) to verify.

  • Recommended: Batteries or USB-C cables for powering the devices.

  • Recommended: LEAPS Manager to configure devices.

Setup instructions

  1. Download LEAPS UDK1 Raspberry Pi Image.

  1. Extract the LEAPS UDK1 Raspberry Pi Archive.

  • Use a program like WinZip or 7-Zip to extract the downloaded LEAPS UDK1 Raspberry Pi zip file.

  1. Launching the Raspberry Pi Imager.

  • Your operating system may try to block the installer.

  • On Windows: If you see a warning message, click More info and Run anyway.

  1. Installing the LEAPS UDK1 Raspberry Pi Image.

  • Insert your SD card into the computer or laptop’s SD card slot.

  • Open the Raspberry Pi Imager.

  • Take extra care to select the correct drive based on its memory capacity.

  • A new WRITE button will appear with “once the LEAPS UDK1 Raspberry Pi Image and the SD card are selected.

../../../_images/raspberry_pi_image_write.png

  • Click the WRITE button.

  1. Writing and finishing up.

  • Wait for the Raspberry Pi Imager to complete the writing process.

  1. Getting started with LEAPS UDK1.

  • Remove the SD card from your computer or laptop and insert it into the Raspberry Pi.

  • Make sure your Raspberry Pi is powered on.

  • The LEAPS UDK1 system is installed and configured to boot with your Raspberry Pi.

  1. Wait for the System to Boot.

  • Please be patient and allow a few minutes for the entire system to finish booting

  1. Connect to the LEAPS-UDK1 network broadcasted by the Raspberry Pi.

  1. SSH into the Raspberry Pi (optional).

  • On a PC (or even another Raspberry Pi), open a PowerShell or Terminal window, then enter the following command to connect to the Raspberry Pi via SSH.

    ssh leaps@192.168.1.1

  • By default the account is leaps and password is leaps.

  1. Use LEAPS Manager to prepare network.

  1. Connection with Gateway Board.

  • Connect the gateway board to your Raspberry Pi using a USB-C Data Cable.

  • Plug the USB-C Data Cable into the USB-C Data Port 1 on your PC. Ensure a stable connection.

  • Will hear two beeps as a confirmation if successfully connected in gateway mode as confirmation.

  1. Check system status (optional).

  • Use the mosquitto_sub command to check the system status. This command will connect to the Mosquitto MQTT broker and display all messages received.

mosquitto_sub -p 1883 -d -v -t '#'

  1. Access LEAPS Center.

  • In a web browser, access the address 192.168.1.1/24. (This can be opened directly on Raspberry Pi or, on a PC that is connected to the LEAPS-UDK1 network broadcasted by the Raspberry Pi - Step 9)

  • If you are on a LAN network, use another computer’s web browser to access the Raspberry Pi’s IP address.

  • Configure the network settings in LEAPS Center to match the network ID of the gateway board you have connected.

  1. Login LEAPS Center.

  • Logging in with Username as admin and Password as admin.

  1. Configure the network on LEAPS Center.

  • Check the network settings in LEAPS Center to match the network ID of the gateway board you have connected.
