ARF7044A

RF32 A 

## **Class2 Bluetooth® module for Data or Audio transmission** 

This miniature module enables **full duplex Bluetooth® data or audio transmissions over 20m** . 

It uses the international 2.45 GHz frequency band as described by European Directive RTTE / EN300-328 / EN301-489 and US FCC part 15 (USA/CAN).This module is **Bluetooth V2 “End Product” certified** , meaning users are able to directly use the Bluetooth® logo. Data transmission and configuration are both managed through UART-type TTL serial interface. The air rate is **723kbps** . **Miniature antenna is included** . 

With the “Data” version, the embedded SPP profile allows the ARF32 module to establish a wireless serial connection with **PDAs, laptops, mobile phones** or any other Bluetooth enabled device. 

The “Audio” versions offer, on top of the data features, an SCO link that supports **HFP, HSP and HSAG profiles** . By using the HSAG profile, the ARF32 module becomes a gateway to **any generic Bluetooth headset** . With the HFP and HSP profiles, and with additional basic microphone and speaker, the ARF32 module becomes a **“hand free” system** . 

Both “Data” and “Audio” versions are extremely easy to use, evaluate and integrate with the tools included in the DemoKits.
