ARF7213B

ARF7213B is a RS232 audio demo kit using ARF7044A Class2 data version Bluetooth module. This miniature module enables full duplex Bluetooth audio transmissions over 20m. It uses the international 2.45GHz 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. 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.
