Download BlueTooth simple serial port Now

Official Description

This simple bluetooth serial port application pairs with any other bluetooth device and lets you transfer 2 bytes (0-255) from the bluetooth device to your android application using the bluetooth serial port protocol (SPP). you can view the two bytes in your android device in graphs and numbers.

In landscape mode there are two graphs that let you see the two numbers over time. In portrait mode you can view the two bytes with no graph.

You can choose how many points to see in the graphs as well.

Sometimes you need to pair the android device from the android bluetooth menu first and than from the application. Pairing from the android bluetooth menu maybe needed only once.

If you need any modifications/changes you can email me.
