This DFRobot Bluetooth Bee Bluetooth wireless module adapts XBEE design. It has a compact size, the pinout is compatible with XBEE which is suitable for all kinds of microcontroller such as Arduino who have 3.3V power out, also the module supports AT commands for parameter setting. (NOTE: You have to use a XBEE adapter for parameter setting. ) The Bluetooth Bee modules comes with an on-board antenna, the antenna provides better signal quality. It acts like a transparent serial port, which works with a variety of Bluetooth adapter and Bluetooth phone. The module has been tested with all the Bluetooth adapter on the market matching to use (with the Bluetooth, including laptops and mobile phones).This arduino bluetooth module fits Gravity Arduino IO Expansion shield, Gravity Mega Sensor Shield, Romeo V2 and DFRduino Leonardo which has xbee socket JavaScript display function display(){ var div1 = document.getElementById(\”div1\”); if(div1.style.display==\”none\”){ div1.style.display = \”block\”; div2.style.display = \”none\”; }else{ div1.style.display = \”none\”; div2.style.display = \”block\”; } } Bluetooth 2.0 Module V3 For Arduino Bluetooth 2.0 Bee Module For Arduino Bluno Link – A USB Bluetooth 4.0 (BLE) Dongle Bluetooth Adapter Mini SKU TEL0073 TEL0026 TEL0023 TEL0087 TEL0002 BLE Chip TI CC2540 CSR BC417143 CSR BC417143 TI CC2540 Frequency 2.4GHz 2.4 ~ 2.48GHz unlicensed ISM band 2.4 ~ 2.48GHz unlicensed ISM band 2.4GHz 2.4 ~ 2.48GHz FHSS Transfer rate 1Mbps GFSK Asynchronous: 2.1Mbps (Max) / 160 kbps; Synchronous: 1Mbps/1Mbps Asynchronous: 2.1Mbps (Max) / 160 kbps; Synchronous: 1Mbps/1Mbps 1Mbps GFSK 3Mbps BLE protocol V4.0 V2.0 + EDR V2.0 + EDR V4.0 V2.0 Modulation GFSK GFSK GFSK GFSK FHSS Power consumption 10.6mA average, ready mode: 8.7mA 10.6mA average, ready mode: 8.7mA Sensitivity -93dBm -84dBm -84dBm -93dBm -84dBm Working Voltage 3.3V +3.5 V ~ +8 V DC and 3.3V DC/50mA 3.3V 3.3V Operating temperature -40 ~ +85 -20 ~ +55 -20 ~ +55 -10 ~ +85 -20 ~ +55 Transmission distance 30m 20 ~ 30m 20 ~ 30m 10 ~ 20m <10m Dimension 32*22mm 40*20*13mm 32*24*9mm 32mm * 16mm 20*16*8mm Weight (g) 10 10 12 10 10 AT command to debug the BLE master-salve machine switch Transparent transmission Wireless programming (Available for Bluno series) iBeacons BLE HID Mobile App Control Key Features support Android and IOS applications,open source code,suitable for secondary development by the user Compatible with APC220 communication interface, can be directly used in I/O Expansion Shield, Romeo, XBoard and etc,.
