I have a cluster of Raspberry Pi 3 machines in a cluster. To reduce power consumption I would like to turn off the wireless modules. I have learnt that HDMI can be switched off with the tvservice command:
sudo tvservice -o
Is there a similar command for wifi/bluetooth?
There is a similar question which discusses disabling wifi (Disable WiFi (wlan0) on Pi 3) but it does not specifically request the power conservation aspect which is what I am concerned with.
