UWB, BLE & wM‑Bus protocol analyzer
For FiRa and CCC Digital Key ranging, and for Wireless M-Bus and OMS metering. Live decryption, slot timelines, triggers, energy and spectrum views, packet replay and a command line for test automation.
The first time you install the app and sign in, a free trial licence is activated.
Two protocol families, one analyzer
Pick the radio you work on. Both share the same packet list, decoder, replay and command line.

UWB (IEEE 802.15.4z) + BLE
FiRa & CCC Digital Key
Everything you need to see inside a UWB ranging session: decoded and decrypted frames, the slot timeline of every round, triggers for your bench, and time sync across sniffers.
Decode and decrypt FiRa ranging
Capture UWB and BLE together and inspect every field, from the IEEE 802.15.4 header to the FiRa ranging payload. Sessions are decrypted live, and BLE connection tracking pulls out the UWB session parameters that hybrid BLE + UWB systems like CCC Digital Key exchange before ranging starts.
See every slot of every round
The Timeline Grid lays UWB traffic out as ranging rounds and slots, straight from your session configuration. Each packet sits in the slot it arrived in, sized by its air time, so a missing poll, a late response or a frame in the wrong slot stands out at a glance. Several sniffers share one grid, colour-coded per board.
Trigger your bench from the air
Build a trigger chain of BLE and UWB events, such as a BLE connection request followed by the first UWB ranging frame, with timing limits and timeouts. When it matches, or fails to, the sniffer fires a GPIO pulse to your scope, logic analyzer or device under test, and the packet list marks where it fired.
Time sync for CCC Digital Key
Line up timestamps across several UWB sniffers with one sync pulse, so cross-board timing means something. For CCC Digital Key, trigger on the BLE connection events that schedule ranging and read UWB timing against them, to check a device starts ranging when the specification says it should.
FiRa IOP and custom decoding
Built for FiRa Plug Fests and interoperability events. Load the iOS and Android DS-TWR presets in one step, capture traffic during a test session, replay problem exchanges and analyse them offline to track down conformance or integration issues, during and after the event.

nRF52840 DK + DWM3000EVB
UWBNordic development kit with the Qorvo DW3000 shield. Widely available and ideal for the lab.
Murata Type2BP EVK
UWB · HPRFNXP QN9090 + SR150 evaluation kit. Adds HPRF capture alongside standard FiRa BPRF.
868 MHz · EN 13757-4 + OMS
Wireless M-Bus & OMS
Decode meters, see the energy behind every telegram, and check the band itself when nothing is getting through.
Wireless M-Bus and OMS, decoded
Listen on the C, T or S channels, uplink or downlink, and choose between a fast wM-Bus link-layer view or the full OMS stack with application-layer records. Add your meter keys and telegrams are decrypted as they arrive.
Match every telegram to its energy
Energy Detect plots continuous RSSI alongside the packet list. Select a telegram and the chart shades the exact burst that carried it; click a burst and the packet list jumps to it. See link margin, the noise floor, and which bursts of energy never decoded into packets.
No packets? Check the band first
When nothing is decoding, Spectrum Scan tells you why. Sweep the 868 MHz band and see at once whether there is traffic in the S, C or T channel, and on the frequency you expect, before you start debugging keys or configuration. A peak-hold trace catches short bursts.

TI LAUNCHXL-CC1312R1
wM-Bus · 868 MHzTI CC1312R LaunchPad running the Bluwbee wM-Bus / OMS sniffer firmware. Captures C, T and S modes, with energy detect and spectrum scan.
Every protocol
Built for the bench
Automate captures from the command line, and replay them for repeatable tests.
Powerful CLI Support
Everything runs headless too. The command line captures UWB, BLE and Wireless M-Bus, prints decoded packets as text or JSON, and updates sniffer firmware — ready for CI pipelines, automated testing and manufacturing.
Packet Replay
For testing and validation, the built-in packet replay feature allows previously captured packets to be replayed — enabling repeatable test scenarios, automated software testing, and end-of-line manufacturing test and calibration. When used with CLI mode, this becomes a complete test automation solution.
Bluwbee sniffer dongles
Compact customer sniffer dongles
Ultra-compact USB sniffer dongles for UWB and wM-Bus, designed for field work and everyday debugging. Plug directly into your host, capture traffic in seconds, and stream data into MantaTrace for live inspection, replay and automation workflows.
