Bluetooth Bee v2.0

Hardware 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.

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.

caution

The supply voltage of this module is 3.3V, higher than this may cause permanent damage to the device. c;;;

Hardware Installation​

Connecting Bluetooth to PC through Uart Bee​

Connecting Bluetooth to Arduino​

Since the hardware UART of Seeedino was used as debug with PC, We choose D2 and D3 to simulate software UART to communicate with Bluetooth. please refer to the jumper setting on below picture

Programming​

Configure the Bluetooth module with Serial Port under Windows​

This section shows how to configure Bluetooth with PC, some basic methods of setting could be learn.

Set up hardware connection refer to "Hardware Installation" section. You will find the blue LED on the module flashes illustrate no connection is set up.
