You have the possibility to communicate directly with the NeXus devices without the use of the BioTrace+ software. The GDI DLL gives real-time access to data coming directly from the NeXus-4, NeXus-10 or NeXus-32, via Bluetooth or -if applicable- USB. The DLL can be used for direct access within other applications and requires programming of data processing, filters, etc.


The DLL contains three functions:

  • Init: Initializes the DLL and connects with the NeXus; during initialization a callback function address should be passed. This callback function will be called by the DLL for every data sample that will be received from the recording device;
  • Start: Starts data acquisition at the requested sample rate;
  • Stop: Stops the data acquisition.


The DLL is located within a demo-project and is made available after paying a fee per license key. The how-to use information is included in the source files after opening the project in visual studio and on request there is a short video available of the demo application and the basic usage of the DLL.
