OBD-II Bluetooth 4.0 Wireless OBD2 KW903 Mini Wi-Fi Car Auto Diagnostic Scan Tools for Apple iOS And All Android Devices (Black with Red)

This device is not Bluetooth 4.0, it is WiFi. Why you label like BT? Never mind...It works perfect on Android only with Torque App like it is wrote on manual, but cannot connect to device via DashCommander which is mentioned too in manual. I wrote in Google Play than DashCommander did not support WiFi OBD2 tools on Android version, only on iOS. I try a few more Android Apps, but cannot connect.The OBD2 tool is good, but for now it must be used only with Apps mentioned in its manual(Torque and DashCommander(iOS only for now))EDIT: After some days with this device can say that it works and other 3 Android Apps(Car Scanner, CarMaster and EOBD Facile)

Uses WiFi and not Bluetooth as it states. Doesn't work with dash command and works intermittently with torque as it keeps disconnecting and torque struggles to find it again. As its WiFi it means you can't use your internet on your device as normal. Don't waste your time with this.

This is a WiFi dongle, not Bluetooth, and as such does not work well e.g. with LeafSpy software. Returning to Amazon.

Had to return because it wouldn't communicate with the ECU of any of my cars.
