ADEUNIS ARF32 User Manual
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.
