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.
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.
This module is extremely easy to evaluate and integrate with tools included in the DemoKits. |
