How can developers get started with all this hardware and software?  There are two major choices depending where the customer is in development. If they want to quickly prototype how Bluetooth SMART would work in an application, then the SimpleLink SensorTag is the best place to start. If they are ready for product development with an easier debugging environment, users can use the development kit shown on the right which includes two LCD-enabled base boards and two RF-optimized EM boards. The CC2650DK also comes with a Bluetooth Smart USB stick to leverage TI’s PC-based tools.
