STEVAL-SPBT3ATV3 USB dongle for the Bluetooth® class 2 SPBT2632C2A.AT2 module Data brief Features ■ Based on a V3.0 Bluetooth® class 2 module SPBT2632C2A.AT2 ■ USB interface and power supply ■ Supports reprogrammability via USB interface ■ Reset button ■ Antenna onboard ■ RoHS compliant Description The STEVAL-SPBT3ATV3 demonstration board is a design tool to evaluate the SPBT2632C2A.AT2 module in a quick and simple way. The dongle includes the RF antenna and the USB connector. The USB connector is used to connect the dongle to a PC, to access the Bluetooth® module, and to supply the dongle. The STEVAL-SPBT3ATV3 includes downloaded FW, enabling the user to create a Bluetooth® link with simple AT commands. The AT command list is detailed in the User Manual UM1547. The AN4127 application note describes how to get started with the STEVAL-SPBT3ATV3. The SPBT2632C2A.AT2-based dongle is a demonstration tool only, to be used strictly for evaluation purposes. It is not a product in itself.
