Bluetooth Bee is an easy to use Bluetooth SPP (Serial Port Profile) module compatible with existing Xbee sockets, designed for transparent wireless serial connection setup.
 
Serial port Bluetooth module is fully qualified Bluetooth V2.0+EDR (Enhanced Data Rate) 3Mbps Modulation with complete 2.4GHz radio transceiver and baseband. It uses CSR Bluecore 04-External single chip Bluetooth system with CMOS technology and with AFH(Adaptive Frequency Hopping Feature).It even has the smallest footprint as small as 12.7mmx27mm. Hope it will simplify your overall design/development cycle.
 
Features
  • Typical -80dBm sensitivity.
  • Up to +4dBm RF transmit power.
  • Fully Qualified Bluetooth V2.0+EDR 3Mbps Modulation.
  • Low Power 1.8V Operation, 1.8 to 3.6V I/O.
  • PIO control.
  • UART interface with programmable baud rate.
  • Integrated PCB antenna.
  • Bee compatible headers.
  • Dimensions : 12.7 x 27mm
Software Features
  • Default Baud rate: 38400, Data bits:8, Stop bit:1,Parity:No parity, Data control: has.
  • Supported baud rate: 9600,19200,38400,57600,115200,230400,460800.
  • Use CTS and RTS to control the data stream.
  • When a rising pulse is detected in PIO0, device will be disconnected.
  • Status instruction port PIO1: low-disconnected, high-connected;
  • PIO10 is connected to red led, PIO11 is connected to green led. When master and slave are paired, red and green led blinks 1time / 2s in interval, while disconnected only green led blinks 2 times/ s.
  • Auto-connect the last device on power as default.
  • Permit matched device connect by default.
  • Default PINCODE:?0000?.
  • Auto-reconnect in 30 min when disconnected as a result of beyond the range of connection.

Applications

  • As a Wireless Serial Port for Arduino / Seeeduino and other MCUs
  • As a Bluetooth Serial Port for PC when connected with UartSBee

Cautions

  • While using with Seeeduino / Arduino, set the operation voltage to 3.3V. Else use a the logic level converter available on Evola.
  • While using with UartSBee, set the operation voltage to 3.3V
  • Command to change baud rate is persistent even after reset. Hence remember the baud rate for next use.
