# GPSMap A Blazor Server app to monitor an Azure IoT Hub and map the GPS coordinatess sent to it as telemetry. Uses Telerik Map Component.

---

## Updates - **Scrolling** map < > Up and Down works, Recentres if location is more than 200m off centre. - **6X Replay** option _( Default telemetry period is 1 / 10 sec, so 6x is 1 min of telemetry / 10s )_ - **WorkInProgress** branch has been merged back into Master - Much improved **NMEA GPGGA** sentence filter. - Can record and playback history - Can jumper GP12/13 for selecting between two wifis and whether or not to use Serial. Can also select Blutooth, GP11 - GP13 _High = _Deskyop WiFi , alt Mobile Wifi_ - Have dev WiFi and my phone wifi for when mobile - GP12 _High = _Serial enabled_ - GP11 _High = _BT enabled but Serial takes precedence_ - If Serial/BT enabled, it blocks if no Serial/BT connected.

 **_A typical GPS Device, suitable for Arduino use_** ## About This project is a coming together of the 7th Arduino Sketch (Azure_IoT_Hub_GPS) on GitHub at [djaus2/RPI Pico W GPS and Bluetooth](https://github.com/djaus2/RpiPicoWGPSandBT) and the [Telerik Map Demo](https://demos.telerik.com/blazor-ui/map/overview). It started out as an endeavour to map that Sketch's IoT Hub telemetry in Azure IOT Central but this was deemed a simpler approach. This app maps the current location of the GPS device.  **_The App showing the location of the GPS device_** ## Azure Sketch As per the seventh Sketch in [djaus2/RPI Pico W GPS and Bluetooth](https://github.com/djaus2/RpiPicoWGPSandBT) but modified specifically for this app. - Json is single level. - eg. ```{"lat":-37.7468138,"lon":144.8956847,"alt":64.6}``` - Includes Cloud to Device Messages that are interpreted as Telemetry config _(case sensitive)_ commands: - Reset - Restarts the telemetry timing - At first is 1s but doubles each send until it reaches 60s. - Start - Restarts telemetry without any change to the period. - Stop - Stops telemetry without any chnage to the period. - Set-Period - Set the telemetry peroiod - The command is Set separated using a highen to: - The period, a numerical parameter in milliseconds - eg. ```Set-30000``` sets the period between sends to 30 seconds _(approx)_. > Have added abilty to send commands from GPSMap app to the device. ## Getting Started Setup the above Sketch in an Arduino Pico W. See [djaus2/RPI Pico W GPS and Bluetooth](https://github.com/djaus2/RpiPicoWGPSandBT) . You will need a Telerik license, whether a full license or a 30 day trial. Follow the steps as below3 at [First Steps with Server-Side UI for Blazor](https://docs.telerik.com/blazor-ui/getting-started/server-blazor?_ga=2.73417493.680605814.1692843673-472055910.1692083918&_gl=1*13uct7u*_ga*NDcyMDU1OTEwLjE2OTIwODM5MTg.*_ga_9JSNBCSF54*MTY5Mjg0MzY3NC44LjEuMTY5Mjg0Mzc4NC4xMS4wLjA.) - Step 1: Download Telerik UI for Blazor - Step 2: Add the Telerik NuGet Feed to Visual Studio - Step 3: Install the Telerik UI for Blazor Components The other steps have been implemented in the project. Azure IoT Hub and Device - As used with Sketch 7. - Having created them need Hub name. Now open this project and add your connection details in appsettings.json: - "HubName": The IoT Hub Name - "HubConnectionString": The IoT Hub connection string - On the left-side pane of your IoT hub, select Shared access policies - From the list of policies, select the service policy. - Copy the Primary connection string. - "DeviceId": The target device's Id - "EventHubConnectionString": The Endpoint - Go to the **IoT Hub** in **Azure Portal** - Select **Built-in endpoints** - Scroll down to **Event Hub compatible endpoint** - Select the **Endpoint** OR If you have [Azure Cli installed](https://learn.microsoft.com/en-us/cli/azure/install-azure-cli-windows?tabs=azure-cli). - Create an azcli prompt and login - Run ```az iot hub connection-string show -n --policy-name service --key-type primary``` - Run ```az iot hub connection-string show -n --default-eventhub```

## Operational Modes: - Live: Scan through historical telemetry then map wrt live telemetry - Historical: Scan though al previous telemetry (typically a day) then replay in timely manner. - Can set start and end date/time

---

## Footnote If running the Blazor app in development mode, the app can be opened in a phone browser locally using **ngrok** as per the blog post: [Blazor Server Development: Viewing in a phone](https://davidjones.sportronics.com.au/web/Blazor-Viewing_in_a_phone-web.html).
