Capture device as it approaches PC? RRS feed

  • Question

  • Hi,

    Is there any way to sense that a device is within proximity of my PC, and then capture the device ID (and date and time) to then log a record in a database?  Bluetooth?  WiFi Direct?

    We're looking to create an internal commercial solution for our fleet of trucks -- to know when they arrive at each location.  We don't want big GPS-based fleet tracking.. just something simple like a sensor at each location detects (and logs) that a truck has arrived.

    We're all .NET and C# based in our development if that helps.

    Thanks for any help.

  • Hi fiverc,

    If you use Bluetooth, please refer to the following steps.

    1. Pair your Bluetooth device with your PC.

    2. Implement code to detect paired devices.
    This link explains how to find Serial COM ports (including BT devices)
    It should be possible to modify the code so you can find paired BT devices only.

    3. Identify your device.

    4. Use polling to see if your device exist in the list or not and is connected.
    Polling is easy to implement, but you should do it in a thread so it can be easily aborted.
    If the API provides events when devices appears or disappears it is preferable to use the events but I don't know if there is any. You have to read for yourself.

    5. If exists, log a record in a database.

    This page is for Windows 8 Bluetooth API. I hope it will be helpful.

  • Or if you want to save the trouble of having to pair each of the device in trucks to each PC:
