Developing an Android App For a Bluetooth Device

[MarkHaysHarris777]

I have found a bluetooth device that I would like to try and develop an app for.

This would be a new adventure for me.

Device in question:

You will need to contact the company.

... I reviewed most of the site before posting this response. The device is not open;  that means that its codes ( and its blue-tooth interface ) are proprietary. To write your own app will require reverse engineering the device and probing its bt interface;  this is of course possible, but way more work than the device's price tag $129 makes relevant. 

I don't know how their app could not meet your needs;  its a very simple set of values and what it measures is all there is. 

You would be better off making your own device ( ADC  use an mcp3002 ) and read the device with SPI. Keep your own stats and design your own interface.  ( this approach will be WAY cheaper too )

If you're bent on writing your own app for this device you're going to have to get the specs on the device; if the company will not provide those you are left with probing and reverse engineering.
