RF switching server

This Script starts a webserver and turns wireless (wifi & bluetooth) on and off when the right HTTP GET request is sent to the specified port.

GET <HOST>:<PORT>/?action=<ACTION> HTTP/1.1

<ACTION> can be either on, off, toggle or status

The user always receives information on the status of the wireless devices as response.

Requirements

Recommended:

Place the script in any directory of your choice

$ wget https://raw.githubusercontent.com/rasple/hrv-emf/master/server/switch_wireless_server.py
Change to PORT variable in the script if you need one different from the default (31415)
Make it executable

# chmod +x switch_wireless_server.py
Start the script

There are two ways the script can be run automatically. The first one is highly preferred.

Systemd service (systemd distros)

The file rfswitch.service is provided to be used to start the script as a systemd daemon.

Place the script it in the /etc/systemd/system/ directory

Edit the rfswitch.service file to have the correct path to the switch_wireless_server.py script

Reload the daemons to load the new service. Then enable and run it
```
 `# systemctl daemon-reload`
 
 `# systemctl enable rfswitch`
 
 `# systemctl start rfswitch`
```
cronjob (any system)

Use the package manager of your distro to install cronie if it isn't already

# pacman -S cronie

Enable the cron service

# systemctl enable cronie

Edit the crontab of your root user

# crontab -e

Add the following line and replace the placeholder with your path to the script. If you need logs, direct the output to your logfile. Consider however that there is no log rotation.

@reboot /<PATH_TO_THE_SCRIPT>/switch_wireless_server.py > /dev/null 2>&1

On the next reboot, the service should run. Verify with

$ ps aux | grep switch_wireless_server.py

The functionality can be verified with curl. Keep in mind that RF is turned off when the script is first run.

$ curl 'http://<HOST>:31415/?action=toggle'
bluetooth unblocked
wlan unblocked
