pwnagotchi-bt-power

A very simple, silly utility which monitors the Bluetooth interface of a Pwnagotchi and cleanly shuts it down on receiving a command from a mobile phone.

Relies upon the Bluedot Python module and Android app to function.

What I was trying to do is shut my Pwnagotchi off without just yanking the power and gambling with corrupting the microSD card every time. Rather than shoehorn in a button to connect to the GPIO pins and figure out which ones weren't being used by the display I have I decided to make use of the Bluetooth interface on my mobile.

The instructions are simple:

• Install the Python 3 virtualenv utility.
  • sudo apt-get update
  • sudo apt-get install python-virtualenv
• Install the utility.
  • Clone this repo onto your Pwnagotchi.
  • cd pwnagotchi-bt-power'
  • python3 -mvenv env
  • . env/bin/activate
  • pip install bluedot
• Set the utility to start up on boot.
  • I use GNU Screen for this. I've included the bluetooth-power.sh script to make life easier for you.
  • Be sure that the startup script runs as the root user!
• Pair your phone with your Pwnagotchi.
  • RasPi
    • sudo bluetoothctl
    • Type the following commands one at a time:
      • discoverable on
      • pairable on
      • agent on
      • default-agent
  • Phone
    • Settings -> Connections
    • Make sure Bluetooth is turned on.
    • Bluetooth (tap on the word not the switch)
    • Tap on your RasPi in the list.
  • RasPi:
    • 'yes'
    • quit
• Reboot your Pwnagotchi.

To shut down your Pwnagotchi:

• Open the Bluedot app on your phone.
• Tap on your Pwnagotchi in the list.
• Tap the big blue button.
