Run the device simulator UI

To run the device simulator User Interface (UI), complete the following steps:

1. Navigate to the working directory.

2. Clone the device simulator UI and install the dependencies:

   git clone --branch v1.8.x --single-branch \
     https://github.com/NordicSemiconductor/asset-tracker-cloud-device-ui-js simulator-ui
   cd simulator-ui
   npm ci
   

3. Start the development server of the device simulator UI:

   npm start
   

   

   Device simulator UI development server

   The command launches a browser with http://localhost:8080 in the address bar as shown in the following image:

   The device simulator UI loads in the browser.

4. Create a new device for use with the simulator by generating a new device certificate:

   cd ~/nrf-asset-tracker/aws
   # Create a new certificate
   node cli create-simulator-cert
   

5. After executing the above command, copy the endpoint printed from npm exec -- @nordicsemiconductor/asset-tracker-cloud-device-simulator-aws "</path/to/certificate.json>" (for example, http://localhost:25336) and use it in the device simulator UI.

   As shown in the following image, the UI connects to the simulator, which is run through the CLI:
