    Hi all,

    So I've got a bit of a project that Im looking for some suggestions with.
    Essentially, I have a data logger out on remote bit of property. Every day I drive out there and retrieve the stored data physically by serial. I figured, I can make up a little device that lets me wirelessly grab the data from the comfort of my car as a stop next to it.

    What I was thinking:
    - Solar powered battery pack for power supply
    - Arduino to periodically grab the data from the data logger
    - Bluetooth attachment for the arduino
    - I drive past, connect my laptop through the bluetooth connection and download the data that the arduino grabbed earlier
    - Have the arduino clear its memory after to save on memory space

    I'm halfway through a Mechatronics Engineering degree so I'm familiar with these sorts of projects/ the ability to research and teach myself, but I'm looking for any advice, or any problems that you guys might think I'll run into.

    Cheers :)

    It is very easy to buy serial-to-bluetooth devices (plenty on ebay). Your laptop may already have a bluetooth device inside. If so, you only have to add a serial-to-bluetooth device on to your data-logger and you will have a wireless serial connection. Without getting out of the car.

    Bluetooth is very short range though. only a metre or so. And won't work through the metal of the car. So you will have to pull up close!
