Bluetooth Comparison

Now that the dust has settled on MEDC, I’m thinking about how to move forward with the Bluetooth library. I had essentially put development on hold when I first heard that Microsoft were preparing their own source package prior to MEDC. When it was released, I was a little disappointed in their functionality (and compatibility) so I’ve decided to press on improving the Bluetooth.NET library. It’s going to take a few weeks to put together the next version, one key aim is to synchronise the source, samples, documentation and binaries with this next release, some of the previous releases have been binary only.

In the meantime here is a comparison of the functionality available today in the widely available Bluetooth libraries/SDKs:-

Obviously your feedback will help shape the library, so what are the key features you’d like to see added or improved?

  1. Actually, the MS Bluetooth stuff does compile under .NETCF v1 … don’t know why they make it sound like it is only 2005-compatible.

    One thing it has that your library used to have (and would be easy enough to add back without sucking in too much of the OpenNETCF) is the abilty to get the list of previously bonded devices (your library = BondedDevices; ms library = PairedDevices). This is a pretty handy thing to have, as typically I want to access a device that has already been discovered and set up by the user … it is also way faster, as it is just a registry walk.

    Anyway, thanks for your library, it is quite a painless way to ease into bluetooth programming, which I’d never done before.
