Hi all.

I've received an interesting mail from Libelium and their modules. I'd like to share this information with Arduino Community.

"During May's month Libelium has released two new wireless modules for Arduino. The new modules add RFID and Bluetooth communication interface to the Arduino and both have been designed to be plugged in the Arduino Xbee Shield to make it more affordable its acquisition.

The specs are:
Arduino RFID module:

RFID chip: SM125

Frequency: 125KHz

UART interface up to 115200 bps

I2C interface up to 400 kHz

TAG's: Atmel / Temic T55xx and EM4102(Unique)

Antenna: 860 uH 10%, 40 x 15 mm

Working distance: up to 10 cm (depending on the antenna size)

Secure Transmissions: 4Byte password

Sleep mode enabled (20uA)

Modulation: supports Manchester RF/64, Manchester RF/32

Arduino Bluetooth module:

Bluetooth Chip: eUnistone 31308/2

Version: Bluetooth 2.0 + EDR (Configurable BT 1.2)

TX Power: 2.5dBm

RX Sensitivity: -86dBm

Antenna: 2dBi

Outdoor Range: 60 m LOS (Line of sight)

Indoor Range: 40 m NLOS (Non line of sight)

(Range measured between the Bluetooth module for Arduino and the BT Linksys dongle)

Special Options:

  • Minimum and Maximum RSSI thresholds control
  • Adaptive Frequency Hopping
  • Security: Authentication, Pairing and Encryption
  • Store 5 different trusted devices in its internal memory
  • Master or Slave operation supported

Finally I bought the BT module and it worked fine with XBee Shield. Like the old Arduino BT, it supports SPP protocol to transfer the information through AT commands.

Regards.
