Bluetooth V3.0 module class 2 with antenna, supporting SPP and iAP with AT2 command set

The SPBT2632C2A.AT2 is an easy to use Bluetooth module, compliant with Bluetooth v3.0.

The module is the smallest form factor available which provides a complete RF platform. The SPBT2632C2A.AT2 enables electronic devices with wireless connectivity, not requiring any RF experience or expertise for integration into the final product. The SPBT2632C2A.AT2 module, being a certified solution, optimizes the time to market of the final applications.

The module is designed for maximum performance in a minimal space including fast speed UART and 7 general purpose I/O lines, several serial interface options, and up to 560 kbps transmission speed with SPP service active, 250 kbps with iAP1 service active.

Optimized design allows the integration of a complete working Bluetooth modem, including antenna, in the minimum possible size; only an additional external LPO (low power oscillator) is required to enable low power mode capability.

The SPBT2632C2A.AT2 is a surface mount PCB module that provides fully embedded, ready to use Bluetooth wireless technology. The reprogrammable Flash memory contains embedded firmware for serial cable replacement using the Bluetooth SPP profile. Embedded Bluetooth AT2 command firmware is a friendly interface, which realizes a simple control for cable replacement, enabling communication with most Bluetooth enabled devices, provided that the devices support the SPP profile. The SPBT2632C2A.AT2, supporting iAP1 profile, provides communication with Android, smartphone, and Apple® iOS Bluetooth enabled devices.

An Apple authentication IC is required to exchange data with an Apple device or access an Apple device application. The AT2 FW includes the Bluetooth SPP profile capable of recognizing the Apple authentication chip.
