Super Easy project for me. We have done android apps for communicating with bluetooth devices. All we need is to get the bluetooth communication protocol of the BMI device and how the screens should be. We can also design the screens as per our idea.
So it will be like this, when you open the app, it will show the list of available bluetooth devices paired .. select the BMI device and it will be connected. then the app ill query the BMI device to get the data and processed and display on screen
Please award the project to us
