The Device Gateway SDK is an API wrapper for .NET developers that makes custom listener development with Cygnus Track easier than ever before. Designed for use with Microsoft Visual Studio 2008 or higher, the Gateway SDK is added as a reference within your project and automates most of the communication between the Cygnus Track Device Gateway and your device listener.

If you are developing a custom device listener with the Gateway SDK, the best way to start is by downloading one of the sample listeners that we've developed to help guide you through the process. You can use any of our sample listeners as a base to develop you own custom listener for any device you wish.

The Gateway SDK package comes with a compiled help manual (CHM) that you can use for reference. A web-based version of this documentation is also available online.

If you're developing a custom device listener with our Gateway SDK and are experiencing difficulties getting your device to post data to Cygnus Track, check the Gateway Message Log. Once you enter your account's API key and the device ID, you'll be able to see a complete log of all successful and unsuccessful communications between the Gateway and your device. This is extremely helpful in diagnosing and correcting communication problems.
