Disable Wifi/BT on pi0 W
Posted: Tue Jun 13, 2017 2:02 pm
I commissioned someone on fiverr to come up with come code to disable wifi and bt since I do not know how to write code. The code he came up with was not quite right so @hoolyhoo came to the rescue. The code allows me to turn on the WiFi and Bluetooth using tactile buttons hooked up to GPIO pins 23,24 and any ground. Wifi and Bluetooth are booth disabled at startup by default, to have them enabled at start up change both "button_bt_status = True" and "button_wifi_status = True" to False. Make sure to follow Hoolyhoo's instructions at the top of the Wifibluetooth.py code.
To create the script type the command below in the following directory /home/pi/Script/. Copy and paste the WifiBluetooth.py code below and save and exit.
WifiBluetooth.py code
To create the script type the command below in the following directory /home/pi/Script/. Copy and paste the WifiBluetooth.py code below and save and exit.
Code: Select all
sudo nano WifiBluetooth.pyCode: Select all
"""
Before running the script please:
a) Install the following packages:
sudo apt-get install python-gpiozero
sudo apt-get install rfkill
b) Define GPIOs lines in global variables
Running the script in command line:
python WifiBluetooth.py
Running script automatically on boot:
Make and add python script to this directory: /home/pi/Script/
sudo nano /etc/rc.local
Add this line before exit 0:
python /home/pi/Script/WifiBluetooth.py &
Save, exit and reboot
