Bluetooth PRO Shield for Raspberry Pi, with Antenna US$190.62

Bluetooth PRO Shield for Raspberry Pi, with Antenna

The Bluetooth PRO Shield for Raspberry Pi consists of two components: A Bluetooth PRO Module and the Raspberry Pi to Arduino Connection Bridge that contains an XBee socket into which the Bluetooth PRO Module will connect.

The picture shows these components mounted on a Raspberry Pi board for illustration only. The Raspberry Pi board is not included.

The Bluetooth PRO Shield for Raspberry Pi is designed to discover a high amount of Bluetooth devices with its RSSI and Class of Device (CoD). It allows you to achieve serial communication between your Raspberry Pi and Bluetooth devices. The Bluetooth module contains the Bluegiga WT12 Bluetooth chip, which is a Class 2 device supporting Bluetooth 2.1 + EDR.

You can use the free arduPi library which allows you to use your Raspberry Pi with the same code used on an Arduino. To do so, the library implements conversion functions so that you can control all the I/O interfaces (I2C, SPI, UART, analog, digital) on the Raspberry Pi the same way as on an Arduino. See the user manual for details.

Bluetooth Module PRO Features

  • Bluetooth Chip: Bluegiga WT12
  • Version: Bluetooth 2.1 + EDR, Class 2
  • TX Power: Seven power levels from -27 dBm to +3 dBm
  • RX Sensitivity: -90 dBm
  • Antenna: 2 dBi
  • Range: from 10 to 50 meters, depending on TX power and environmental conditions
  • Received Signal Strength Indicator (RSSI) for each scanned device
  • Class of Device (CoD) for each scanned device

Special Features

The Bluetooth Module PRO integrates a firmware called iWRAP, which offers many possibilities. The iWRAP Bluetooth stack implements 13 different profiles and Apple iAP connectivity. Follow the link below to the Bluegiga web site for details.

A specific API has been developed to allow use of this module with a Waspmote sensor platform. There are many useful functions which can be used as a guideline for other designs.

Power Consumption

The Bluetooth module's power usage depends on its operating state. Refer to the following table.

State Usage
Sleep< 0.5 mA
On (Idle)2 mA
Inquiry @ min. power33.5 mA
Inquiry @ max. power36.5 mA
