Features:
Compatible with 12V petrol and diesel cars, NOT COMPATIBLE WITH TRUCKS.
WIFI ELM327 V1.5 OBD2 auto scan tool for Android, iOS.
Hardware V1.5, Software V2.1.
WIFI OBD2 can automatically detect and interpret various protocols.
It also provides support for high-speed communication and a low-power sleep mode.
It uses AT commands to communicate with a host device (PC, Notebook, iPhone, iPod touch, iPad, Android, etc.).
Numerous software packages are available that are fully compatible with WI-FI OBD2.
Some of them have quite useful functions, such as monitoring engine operating parameters, reading and deleting DTCs, MPG meter, etc.
You can also write your own software on a specific hardware platform if you wish, because the AT commands are fully documented and very well explained.
