Bluetooth 4.0 OBD2 Scanner ELM327 Adapter for iOS Android PC

Most cheap Bluetooth OBD2 adapters share one silent flaw: Bluetooth Classic will not pair with an iPhone. This one is built on Bluetooth 4.0 dual mode, so the same dongle serves iOS, Android and Windows — plug it into the OBD2 port under the dash, pair from whichever device you carry, and the engine computer opens up through your choice of scanner app: Torque, DashCommand, OBD Car Doctor and Mini OBDII on Android, ScanMaster-ELM, ScanTool.net or PCMSCAN on Windows, Mini OBDII on iOS.

It reads both generic and manufacturer-specific diagnostic trouble codes, clears them and turns off the check-engine light, and streams live sensor data — RPM, coolant temperature, vehicle speed, fuel trims, intake air temperature, throttle position, oxygen sensor voltages and the rest of the standard parameter set. Electricals suit permanent installation: 9 to 16 V operating range, a 25 mA idle draw and a −40 to +85 °C tolerance for engine-bay-adjacent heat. The body measures a compact 48 × 25 × 25 mm, small enough to leave in the port.

Key features

• Bluetooth 2.0 / 4.0 dual mode — iOS, Android and Windows support
• Reads and clears trouble codes, turns off the MIL (check engine light)
• Live sensor data through Torque, DashCommand, ScanMaster and more
• Operating voltage 9–16 V, 25 mA current draw
• −40 to +85 °C operating range, 48 × 25 × 25 mm body

Specifications

Supported protocols

• SAE J1850 PWM (41.6 kbaud) and SAE J1850 VPW (10.4 kbaud)
• ISO 9141-2 (5 baud init, 10.4 kbaud)
• ISO 14230-4 KWP2000 (5 baud and fast init, 10.4 kbaud)
• ISO 15765-4 CAN (11-bit and 29-bit ID, 250 and 500 kbaud)

An honest note: no ELM327 adapter repairs anything by itself — it reports what the ECU reports, and the fixing is still your mechanic’s job. Check that your vehicle is OBD-II compliant (petrol from 2001, diesel from 2004 in Europe; 1996 onward in North America) before ordering.

Typical applications

• iPhone and iPad dashboards for fuel economy and engine health
• Android Torque users who want the full protocol set
• Workshops mixing iOS and Windows scan devices
