Hello!
How to turn off Wi-Fi and Bluetooth devices to reduce power consumption?
armbianmonitor -U -> result in attachment.

Thank you.

Disable aw859a-wifi and aw859a-bluetooth services. For a more paranoid way, you can also add a dtoverlay to disable mmc1 something like

 

/dts-v1/;
/plugin/;

&mmc1 {
	status = "disabled";
};

 

Save above to a file with .dts as extension and run "sudo armbian-add-overlay <filename>"

Here is how I did it with my Orange Pi 3 LTS running the latest Armbian Ubuntu:

 

# systemctl disable --now wpa_supplicant.service

# systemctl mask wpa_supplicant.service

# systemctl disable --now aw859a-bluetooth.service

# sed -i '' '/sprdwl_ng/d' /etc/modules

 

My typical load went from ~1 to ~0.01 to 0.1. 

Or temporarily patch the driver until a better solution presents its self.
