Connection is not stable. More like a cache/variable byte size issue.

Using app with Vgate iCar Pro 4.0 allows me to monitor CVT temp while towing with 2019 Crosstrek. App is very easy to use. It could use some enhancements but not deal breakers (like when setting up the screen you need to go 3 dots, edit, add the sensor. Then instead of allowing you to add another it takes you back to the main screen with the readouts. Then to add another you need to 3 dots, edit etc… not a deal breaker and your not doing that every day so it’s really only a pain once) Only reason gave it 4 stars is lack of CarPlay. It would be great to see on car’s screen. Not sure if that is an Apple or developer limitation.

Huge thanks to the developers for making this app. I have seen that transmission oil light too many times. When I finally found this app and could read the specific readouts of the car I was able to diagnose overheating on my CVT. Luckily a 3rd party OBD sensor from ENGIE is compatible with this app. Making use of older Bluetooth protocols. Huge kudos!! Feature request: Better logging of data so that I can more adequately track trips and climbs. Elevation is an important variable. Roll and Pitch of the vehicle too. I know those are not part of the the ECU however useful to understand the car. Thanks again you are saving my CVTF/ATF from over abuse !
