Quick Overview: Ubertooth One

Ubertooth One is an open-source 2.4 GHz hardware device used to perform experimentation and hack Bluetooth devices. This device can only receive and transmit 2.4 GHz.

Currently, commercial Bluetooth monitoring is too expensive and it can be purchased for around US $15,000. While Ubertooth One is an affordable alternative for the development of Bluetooth technology.

The main purpose of using this tool is to capture and monitor Bluetooth communication. It is to be noted that the Ubertooth device is capable of sniffing Bluetooth Low Energy (BLE) and Bluetooth Classic packets.

The architecture of Ubertooth One

  • RP-SMA RF connector - To connect test equipment, antenna, or dummy load
  • CC2591 - RF front end
  • CC2400 - wireless transceiver
  • LPC175x - ARM Cortex-M3 microcontroller with Full-Speed USB 2.0

What Ubertooth One can do?

The Ubertooth can capture 2.4.GHz signals using a Frequency Shift Keying modulation technique. As mentioned earlier, this device can capture both classic Bluetooth and BLE packets. This device can capture a maximum of 50 byte size packet. Wireshark can be used to monitor and capture Bluetooth packets. Six LEDs are available to indicate the different states of the device. This device can also be used as a Bluetooth Spectrum Analyzer.


There are different Bluetooth sniffers and analyzers available in the market. Still, Ubertooth is a unique one as it is very affordable and easy to use. The whole set of documentation is available to customize the Ubertooth device according to their needs. By using a hardware device, you can able to break smart locks, smart light bulbs, and any other device that is using Bluetooth.
