Won't connect at all. response to developer; I did try all that you suggested, and more. The red power light comes on, but only when I first install it, then eventually goes to sleep without ever connecting to anything, including the app. I have two other scanners that work just fine, as well as a second phone with the same results. As my return window closed a few days ago, you have a chance to remedy this. I will be more than happy to give 5 stars..... When it works.

Possible reasons for not being able to connect 1. The APP does not have Bluetooth and location permissions 2. The car scanner does not support the vehicle's communication protocol For problem 1, you can reinstall the APP and try to authorize it. For problem 2, you can confirm it on another car

Worthless. Dies not connect to vehicle computer. I unplugged device and plug in my professional snap on scanner and that connects immediately telling my all my 10th gen f150 readings perfectly. Then plug this back in and the BT Elm module works great with every single other app than this one which is to badly programmed to even communicate with my ECU, PCM, ABS module. NOTHING at all. And the APP runs .dll. .dat packages on your phone so it is Spyware. BEWARE. BEWARE.

it's ok would be nice if you could make one payment for all the functions. it'd be even nicer if it would stop taking my money and actually give me the functions that I've already paid for

1. Added battery detection function.

3. Fixed some known issues.
