What the app actually does
Every capability listed here is implemented in the shipping app. Nothing on this page is a roadmap item.
Overview
Protocol matrix
| Bus | Transport | What it does |
|---|---|---|
| CAN (classic + FD) | USB — PEAK PCAN-USB / PCAN-USB FD, and CANable/SLCAN-class adapters | Live monitor, ID and signal filtering, transmit (single or periodic), DBC signal decode, live plotting, native ISO-TP + UDS diagnostics, J1939 PGN/SPN decode |
| OBD-II | ELM327 over USB, Bluetooth Classic (SPP), Bluetooth LE, or Wi-Fi/TCP | 23 live PIDs, current/pending/permanent fault codes, freeze frame, VIN and ECU info, automatic supported-PID probing |
| Modbus | RTU over USB or Bluetooth serial, or Modbus TCP | Sniffer plus read/write master — coils, holding and input registers, live register plotting |
| Serial | USB, Bluetooth (SPP or BLE), or TCP | Raw terminal with configurable framing |
Bus family
CAN and CAN FD
Connect a PEAK PCAN-USB or PCAN-USB FD, or a CANable/SLCAN-class adapter, over USB. The live monitor shows frames as they arrive, with filtering by identifier and by decoded signal so a busy bus stays readable.
Transmit single frames or set up periodic transmission. Import a DBC file and raw frames become named, scaled signals — plotted live if you want to watch a value move. J1939 PGN and SPN decode is built in for heavy vehicles and machinery.
ISO-TP and UDS are implemented natively on top of the adapter, so diagnostic sessions do not depend on an ELM327 sitting in the path.
CAN capabilities
- · Live frame monitor
- · ID and signal filtering
- · Transmit — single or periodic
- · DBC signal decode
- · Live signal plotting
- · Native ISO-TP + UDS
- · J1939 PGN/SPN decode
- · CAN FD
Bus family
OBD-II
Works with ELM327 interfaces over USB, Bluetooth Classic (SPP), Bluetooth LE or Wi-Fi/TCP — whichever adapter is already in the toolbox.
The app probes which PIDs the vehicle supports, then streams 23 live PIDs. Read current, pending and permanent fault codes, inspect freeze frame data, and pull VIN and ECU information.
OBD-II capabilities
- · 23 live PIDs
- · Current / pending / permanent DTCs
- · Freeze frame
- · VIN and ECU info
- · Automatic supported-PID probing
Bus family
Modbus RTU and TCP
Modbus RTU over a USB or Bluetooth serial link, or Modbus TCP over the network. The sniffer shows traffic between an existing master and its slaves without joining in.
As a master, read and write coils, holding registers and input registers, and plot register values live while a machine runs.
Modbus capabilities
- · RTU over USB / Bluetooth serial
- · Modbus TCP
- · Passive sniffer
- · Read/write master
- · Coils, holding + input registers
- · Live register plotting
Bus family
Raw serial
A raw terminal over USB, Bluetooth (SPP or BLE) or TCP, with configurable framing — for proprietary protocols, bootloaders and bring-up work where nothing is standardised yet.
Across every protocol
Replay, export and Demo Mode
Log replay
Open a previous capture and replay it through the live UI at 1×, 2× or 4× — the same views, away from the vehicle.
Export
CSV, PCAP, ASC and BLF, so a capture opens in the desktop tooling your colleagues already use.
Demo Mode
Simulates every protocol, so the app can be evaluated end to end with no hardware at all.
