Page 4  VERVIEW The Laird DVK-BT900 development kit provides a platform for rapid wireless connectivity prototyping, providing multiple options for the development of Classic Bluetooth and Bluetooth Low Energy (BLE) applications. This manual is for Rev. 01 and later of the development PCB and relates to DVK-BT900-V01 and later on the silkscreen of the PCB motherboard itself.
Page 5 BASIC applications are simple and easy to develop for any BT / BLE application. Sample BASIC applications are available to download from the Laird’s BT900 product pages or via the Technical Support Site https://laird-ews-support.desk.com/ The BT900 development board is a universal development tool to highlight the capabilities of the BT900 module. The development kit is supplied in a default configuration which should be suitable for multiple experimentation options.
