# Bluetooth Packet Decoding

If the output to the Bluetooth module is viewed on a computer, it is not human-readable, so the packets need to be decoded. Instead, you will see something similar to below:

If you want to view the output on a computer, there is a Python script to do that at <https://github.com/eChook/Python-Serial-Interpreter>. This requires Python 3.x with pySerial and tkinter installed.

The interpretation code used in the Android app is available [here](https://github.com/eChook/eChook-Android/blob/master/app/src/main/java/com/ben/drivenbluetooth/threads/BTStreamReader.java).
