Cytron Bluetooth Module

  • Availability:
  • Product Code: BLUEBEE
  • Warranty Period: 12 months
This BlueBee wireless module is new product from Cytron Technologies, utilizing the XBee form factor, BlueBee is compatible with XBee adapter such as SKXBee (without module), XBee breakout board and Arduino-XBee shield. Though the form factor (pin out) is compatible with XBee module, BlueBee uses Bluetooth Technology. It is compact in size, the pinout is compatible with XBee which is suitable for all kinds of microcontroller systems that have 3.3V power out, the module utilize AT commands to set baud rate and other parameters.

The BlueBee module 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. However, it only provides SPP (Serial Port Profile) where it becomes serial COM port once it establish connection with master Blueooth.

BlueBee module's baudrate can modified using XBEE adapter. You can use SKXBEE-BOARD or XBEE Arduino controller receives the base plug, enabling Bluetooth wireless control.

Please note that the current version BlueBee Bluetooth module is only a slave module master and slave module. Communication among two BlueBees is not possible. Normally connection is initiated from Bluetooth Dongle (Laptop or computer), or Handphone that have Bluetooth. To enable BlueBee in master mode, please refer to this tutorial.

Q & A (12)
Is there anyway to link it to a micro:bit V1? ( Joshua Kordek, 10/01/2021 )
Hi, micro:bit has already have built-in (Wireless Communication, via Bluetooth BLE and 2.4GHz Radio). Thanks :)
Hi can you make a demo for the use of this product? ( Syed Shahul Hameed S/O Syed Serajudeen , 17/08/2020 )
Hi, you may reach our technical team at support@cytron.io for technical assistance ya. Thanks :)
Hi, this bluetooth can connect with android right? ( yana, 30/03/2019 )
Hi, yes you can connect it with Arduino :)
I want to use this module to automatically connect to my app in android phone without pairing process. Is there a way to do bypass or remove the pairing process? ( Aravinthan Varatharaju, 09/05/2017 )
We are not sure about auto connect to Android app. However you can consider to read Using BlueBee in Master mode tutorial. This tutorial shows how the Bluebee can request and create connection to another Bluebee. For further question please post to our technical forum, as this session is only for short inquiry. Thanks.
can this Bluetooth Module interface with microcontroller PIC18F2550 ? Thank you very much ( DHA, 27/09/2016 )
Hi, yes.  If you have further question, you can ask at our technical forum, as this session is only for short inquiry. Thanks. :)
I'm looking to use this blueetooth to connect to my arduino using IOS for simple serial command and reading and writing internal registers/status. I do not want to write my own program in IOS since it is just a simple "serial terminal" and I don't own a mac but I'm worried with the compatibility with the IOS programs available. Is this bluebee compatible with any of these? 1.)OpenBLE 2.)Lightblue explorer 3.)nBlueterm ( TWC, 19/07/2016 )
Hi, this bluebee is not supported for IOS. However, we carry other bluetooth module BlueBee 4.0 which might suit your needs. It is BLE module and it is confirmed it can be connected with IOS. For further inquiry, kindly visit our technical forum as this session in only for short inquiry. Thanks :sl
Can I connect Cytron Bluetooth Module v4.0 Dual Mode with Arduino Uno microcontroller without XBEE shield? if so, what should i do with the connection of the module with the Arduino microcontroller? ( Tan, 26/11/2015 )
Hi. Yes, you can. You can use the 5V I/O interface to connect with Arduino controller. Vcc -> Arduino 5V, GND to Arduino GND, RX to TX of Arduino and TX to RX of Arduino. For more information about hardware and software UART connection you can visit our technical forum as this session is only for short inquiry. Thanks :)
This module can be used to interface with 8051 or not? ( Max, 17/04/2015 )
Can :) As long as the controller have UART.
Need to know that which other module we need to program this module? ( MAT, 08/01/2015 )
You can utilize the SKXBee or Xbee shield to configure it from computer. Please do refer to the User's Manual, and the tutorials :)
Hi, may i know what is the possible causes for the bluebee always not connected? Is it the logic converter needed for tx rx pin of arduino board to tx rx pin of bluebee? Thanks. ( MFY, 10/12/2014 )
Are you using Xbee shield? Please do continue the discussion in our technical forum so you can share more information. This section is for short inquiry, thanks :)
