I purchased a Bluetooth WitMotion BWT901CL and did the initial setup on my Galaxy S7 (Android 7) using their apk with no issues. When I connect the device over Bluetooth to the PX5, it shows up as an OBD scanner. I attempted to install the apk on the PX5 but it crashes upon startup.
I then decided to attempt using a USB connection and purchased a USB to TTL cable and ended up with nearly the same results. When I plug the WitMotion in, I get a "Which app do you want to use this device" message, either iBus (BMW app) or Torque. Neither which are going to help me.
Regardless of USB or Bluetooth, when I open a compass app, it tells me there is no Magnetometer in my device and closes. Same for Google Maps, Waze, etc.
Has anyone successfully installed something like this? I found this tread, but with no solutions
