As a previous RPi user I am used to the raspi-config command and sudo nano to edit the configuration of the device.
I have a few devices deployed and have a situation where I would like to disable the WiFi adapter, Bluetooth and set manual IP addresses in stead of DHCP.
Traditionally I would access my RPi devices and run the ‘sudo raspi-config’ command and change the desired settings.
These obviously are not available on my BalenaIO build devices.
I can run the Terminal to the ‘Host OS’
Can anyone give any advice how I may achieve the reconfiguration via the command line in the Host OS terminal screen please?
Thank you for the reply @gelbal although unfortunately it does not help…
The guide talks about creating a wireless access point…
All I want to do is turn off the Bluetooth and the wireless on the RPi unit which is running out in the field.
The directories and commands in the guide do not exist or work on the BalenaIO build.
It gives an example :-
#!/usr/bin/env python
import dbus, uuid
Not meaning to sound blunt, I appreciate it is my understanding of the BalenaIO OS at fault here but the guide is of no use for what I am trying to achieve and does not work to turn off bluetooth and wifi.
I need to understand the setup in more detail and where I am used to a simple configuration file command like the following:-
balenaOS uses NetworkManager to manage the connection. The documentation explains in detail on how you could manage the connections. If the documentation is not helpful or lacking, your feedback is appreciated.
As detailed in the doc, once you ssh into host OS, you could edit NetworkManager’s configuration to change the connection to be ethernet only (or in other ways). To edit the file: vi /etc/NetworkManager/system-connections/resin-wifi-01
Before you turn off the wifi connection, make sure you have other ways of accessing the device via a direct physical connection or another networking setup in place (like ethernet conection). Else, you will lose remote access to the device.
Then also use NetworkManager’s nmcli to disable the wifi if you don’t want to persist the configuration: nmcli radio wifi off
Next, you are right, I don’t see any mention of bluetooth in that documentation. So hcitool dev will output the bluetooth devices and systemctl status bluetooth shows the running bluetooth service. You could turn off the bluetooth via: systemctl stop bluetooth.service
and disable it: systemctl disable bluetooth.service
A reboot might be necessary for the disabling. Hope these are helpful.
The config.txt is on the boot partition so it can be modified without issues. The easiest way to modify it is through the dashboard as explained in the second link. Then balena supervisor will handle the definitions from the dashboard and apply the changes to config.txt. This way you could setup these variables once for your whole fleet instead of editing these one by one on each device.
