Yes Is there software to receive and decode Bluetooth packets? You could try gr-bluetooth, but it's not maintained. Would this be practical? Bluetooth is actually a set of protocols rather than just one, most of them hop frequency hundreds to thousands of times per second.
There is likely to be a significant, but not insurmountable, amount of development effort involved in sniffing the Bluetooth protocols included in the Bluetooth 5 specification. Skip to content.

Can I use HackRF One as Bluetooth 5 sniffer?
You signed in with another tab or window. Reload to refresh your session. You signed out in another tab or window.The Bluetooth specification is huge and quite complex. As a researcher, it helps when looking at the various Internet of Things IoT devices to understand what a vendor of an IoT device actually implemented.
This is important when one has to deal with environments where older and less secure Bluetooth implementations on older IoT devices have to interact with the new IoT devices which are capable of better security, and you have to determine what security is actually being used. Before we explain current Bluetooth security, we should go back in time a bit. Bluetooth was invented inbut really came into use during the s. There is no one Bluetooth protocol; it is a collection of different protocols grouped together under a single specification.
In an effort to explain a concept like LE Privacy, we must explain a chunk of the Bluetooth history of security implementations. Eventually, these were combined in Bluetooth 4. Remember that comment about Bluetooth being complex?
The current standard, as of this writing, is Bluetooth 5 there is no 5. As we will see later on, a lot of IoT vendors try to support legacy authentication protocols dating back as far as Bluetooth 2.
In the OSI Model, there are seven layers—yes I can hear you groaning—but I just need to reference a few of them quickly. It is responsible for pairing, encryption and signing.
As mentioned earlier, with Bluetooth 4. These are simply groupings of characteristics, but their nature affects the security aspect of various devices, so it helps to know the background.
Bluetooth Smart is implemented on peripheral devices like headphones, speakers, fitness trackers, medical devices and so on. These devices are battery-powered and often pair to devices that they may lose contact with for extended periods of time. They may only require periodic connection to their paired host, like during data transfer.
Additionally, they can maintain a pairing despite long sleep periods between wake modes—even preventing a second device from pairing. Bluetooth Smart Ready are devices that can talk to Bluetooth Smart and use all of the capabilities. Your smartphone or your laptop are good examples of Bluetooth Smart Ready devices. If you have an old Bluetooth 2.The purpose of this blog post to be the first of a series covering the topic of Bluetooth Low Energy sniffers.
So I wanted to take this opportunity and document my learning as well as put it out there to benefit anyone else looking to learn more about BLE sniffers. As you can see there are many options out there for BLE sniffers and they vary widely in features and pricing. There is no perfect sniffer and your budget will probably determine which one you choose. In the upcoming posts, I will go over how to use the TI BLE sniffer to determine the devices that are advertising in the area, make sense of that data, how to follow connections and analyze the data transfers happening between the master and slave.
Ian I was about to ask the same thing — why not find a way to use 3 cheap USB dongle sniffers to sniff all the advertising channels. I have done something similar with WiFi cards sniffing 2 WiFi channels and wireshark can aggregate that. The beauty is you can sniff BLE and It works really quite well and is cheap and easy to use. I know that the dongle cannot be used with nRF Connect to discover extended advertisements or at least not yet. Hi I am somewhat new to this.
My company is developing an app that enables BLE on devices for lamps and switches. Is there a way to sniff the traffic being sent without using any hardware at all? Or is it mandatory to have one of the hardware devices mentioned in your previous article? Unfortunately, yes you will need sniffer hardware in order to capture BLE traffic. Hi Mohammad. Very useful article, thanks.
Does it really perform better than the Nordic and TI sniffers in this regard? Do you know if the Ubertooth One does support this feature? Which of these three sniffers do you prefer to work with? Unfortunately, I do not have much experience with the Ubertooth One. At one point, I tried going through the setup to get it working on my Macbook, but it was a bit more involved and gave up too soon. Martin, do you know if the peripheral device is set up to advertise on all 3 advertising channels or just one?
Do these notifications happen while the connection is alive between the master and slave? I had a Peripheral device that would send 4 notifications every 40 ms. How to use a Bluetooth Low Energy sniffer without pulling your hair out! Pros: Relatively easy-to-use, reasonable cost, minimal setup required.
Pros: reasonable cost, integrates with Wireshark Windows only through the use of Nordic nRFSniffer software command line utility. Cons: can listen on only one advertising channel at a time hardware limitationa bit of setup required, drops packets occasionally.
Pros: very low cost, fully supports Bluetooth 5 as a development kit, integrates with a full suite of applications from Nordic, the nRF Connect for desktop. Though, this is inevitably coming. Pros: open-source software and hardware. Cons: can listen on only one advertising channel at a time hardware limitationdifficult to get set up on Mac OS X or Windows much simpler on Linux. Pros: can listen to all 3 advertising channels simultaneously, compact design, powerful PC software almost overwhelmingly powerful.Developers and test engineers rely on FTS4BT to get them through the design, debug, test, verify, and qualification cycle.

You see all packets as they happen in the air! Regardless of the number and type of Bluetooth devices, node topologies, types of technologies, roles and protocols. A true wideband receiver, tuned and configured according to Bluetooth baseband specifications.
You may record and view even all traffic which happens already before the Bluetooth connections are established, see the inquiry and paging packets of Bluetooth Classic states. Similarly, you can follow all advertisement packets and extended advertisement of Bluetooth Low Energy.
SODERA analyzer lets pair and bond the devices and run the whole communication sessions of the tested device s in the exact same manner as when no sniffer is present, it allows having no regard for its own measurement in the background. The developer may enter the relevant decryption key data even when the capture stage is finished and the traffic is already captured.
It enables the developer to choose the best way and the proper moment to explore the decryption data from his device under test and to hand them over to SODERA.
Say goodbye to often artificial measuring scenarios which required to enter the encryption keys in advance of the measurement or which stressed the developer to resign to watch and to test some kinds of encrypted sessions.
Make your products more secure. HCI is present in many Bluetooth devices. Concurrent captures allow correlating HCI commands and data with the Bluetooth packets in the air. The latter allows comprehensive look plus an easy and fast user control to check the correlation of the digital signal changes with Bluetooth over-the-air sent packets as well as precise timing measurements between these events. It does not need any measuring PC to be connected either. On top of that Frontline has developed the optional add-on software modules which comprise the knowledge commonly mastered only by human experts in the Bluetooth technology area.
Their capabilities cover the complex relations of Bluetooth protocols, which normally require overseeing and understanding of multiple data packets and protocol events. Using these Expert System modules, the novice becomes nearly the expert and the real expert may work essentially faster.
They help to discover the root cause. There is one module dealing with more general Bluetooth protocol issues and another one focused on the development of audio transmissions. They can be used together too. The first Bluetooth Protocol Expert System provides the concise in-depth analysis of configuration, Bluetooth profile errors, and HCI or transport issues.One of the biggest challenges of learning any new technology is knowing which tools you need to get started.
In this blog post, I will provide a list of the five most essential tools for developing a Bluetooth low energy product and app. Client Emulator App This can either be a mobile app iOS or Androidor a desktop application connected through a Bluetooth low energy dongle or internal Bluetooth low energy chip. The low-cost sniffers usually have limitations, such as the lack of advanced features on the desktop end as well as not being able to scan the three advertising channels simultaneously.
Using a Bluetooth low energy sniffer can help tremendously in debugging problems with the connection and data transfer between the peripheral and the central device. Bluetooth low energy is selected for two main reasons: the proliferation of Bluetooth low energy in smartphones and the low energy consumption that comes with it allowing you to design devices that can last for years on tiny batteries.
There are different tools that can be used to measure the power consumption during development and testing to help you optimize for low power.
X240 Wideband Protocol Analyzer
The two most common tools are:. Another tool for power measurement is the Nordic Power Profiler Kit which can be used with the nRF51 and nRF52 Development kits, but can also be used with your custom board via a header connector. Bluetooth Specification Document While this is not considered a tool per se, it is still the main reference document for every Bluetooth developer — mobile or embedded. When you run into issues or have questions about certain technical aspects of Bluetooth low energy, the specification document is the best document to refer to.
Access to the released Bluetooth specification docs is completely free. The latest Bluetooth specification can be accessed here. Feel free to share any other tools I may have missed in the list by commenting below. A new Bluetooth direction finding feature allows devices to determine the direction of a Bluetooth signal, thereby enabling the development of Bluetooth proximity solutions that can understand device direction as well as Bluetooth positioning systems that can achieve down to centimeter-level location accuracy.

If nothing happens, download GitHub Desktop and try again. If nothing happens, download Xcode and try again. If nothing happens, download the GitHub extension for Visual Studio and try again. Sniffle is a sniffer for Bluetooth 5 and 4. Note: it should be possible to compile Sniffle to run on CCP Launchpad boards with minimal modifications, but I have not yet tried this. The arm-none-eabi-gcc provided through various Linux distributions' package manager often lacks some header files or requires some changes to linker configuration.
You can just download and extract the prebuilt executables. The TI SDK is provided as an executable binary that extracts a bunch of source code once you accept the license agreement.
Bluetooth 5 Advertisements: Everything you need to know
This works fine and my makefiles expect this path, so I suggest just going with the default here. The same applies for the TI SysConfig tool. Once the SDK has been extracted, you will need to edit one makefile to match your build environment. We don't need the CCS compiler. See the diff below as an example, and adapt for wherever you installed things. It's available for Linux, Mac, and Windows.
Just navigate to the fw directory and run make. You can also flash the compiled sniffle. Be sure to perform a make clean before switching between CC13x2 and CC26x2. The XDS debugger on the Launchpad boards creates two serial ports. The first of the two created serial ports is used to communicate with Sniffle. For the -r RSSI filter option, a value of tends to work well if the sniffer is very close to or nearly touching the transmitting device.
The RSSI filter is only active when capturing advertisements, as you always want to capture data channel traffic for a connection being followed.
