Combining the NXP Bluetooth 2.0 SiP BGB203/H1/S06 with 1SPP firmware, this innovative solution implements a Bluetooth Serial Port Profile (SPP) and can be used to wirelessly transfer data between systems.

The Bluetooth protocol stack runs on the BGB203 processor, and not on the host processor, so it minimizes host processor overhead and can be implemented in a variety of environments. The firmware provides complete Bluetooth functionality and uses a command set that follows standard AT-command syntax. The command interface makes it simple to configure the command set, and there is a configurable escape sequence.

The host accesses the firmware via a physical UART interface that can be configured for a variety of characteristics, including baud rate, word length, parity, stop bits, RTS/CTS flow control, and DTR/DSR flow control. The firmware supports RS-232 signals, working with CD, RI, and DTR/DSR (including pass-through).  It also supports DCE or DTE device.

The BGB203 is a second-generation System-in-Package (SiP) solution for Bluetooth 2.0 wireless connectivity. It provides complete, plug-and-play Bluetooth 2.0 operation in a low-cost package that measures only 49 mm².  Optimized for short-range hosted and embedded applications, it reduces board space, lowers overall cost, and speeds time-to-market for a range of applications that use serial data transfer, including industrial, point-of-sale, and medical systems.
