Bluetooth Diagnostic Interface with WBH-Diag Pro Chip

Vehicle diagnosis can be so simple: Plug in the interface into the jack in the car and make a connection to the computer via Bluetooth - no wires. Thanks to Class 1 Bluetooth chip theoretical range to max. approximately 100 m.

• Firmwareversion: 2.1
• 6 LEDs for status display
• Future proof: Firmware updates are simply made by Bluetooth
• Supported protocol: KW 1281, KW 2000 (KW 2089)
• More information: WBH BT4 Info
• Manual WBH BT4 (PDF)
• Data sheet (PDF): WBH-Diag Pro data sheet
• Software: WBH-Diag Pro Software

The processor contains above named current version for WBH-Diag Pro. The processor can be simply inserted into the circuit and does not have no more be programmed. Subsequent updates are possible via Bluetooth.

With the new protocol interpreter chip WBH-Diag Pro is the vehicle manufacturer-specific diagnostic (OBD) for vehicles from the VAG Group (VW, Audi, Seat, etc.) cheap, reliable and much easier, because regardless of the hardware diagnostic tools.

The heart of it is a microcontroller, which is complete control the protocol (KWP1281, KW2000/KW2089) to the vehicle inspected. The software on the diagnostic tool must be neither the time-critical initialization, nor the protocol level, or worry about the timing. The μC ensures likewise for the fact that a once developed connection to the vehicle remains maintaining. Past are the times, in which problems led with timing by the interface (e.g. with USB) to the break or let only no connection to the vehicle come. Already with a simple terminal program the diagnostic chip can to be addressed and vehicle specifications left to query itself. Owing to the simple command logic therefore individual diagnostic programs can be written without high expenditure and without study of the protocol, which are optimized for the respective targeted application. Like that it is possible, to provide software for each operating system (e.g. Windows, Windows Mobile, Unix, Apple) and each hardware (PDA, Laptop, CarPC etc.). As software developers you can concentrate then completely on the functions of your diagnostic tools.
