How do I configure the network under Bullseye? How is this different from previous versions such as Stretch?

• Since the release of the Bullseye image, there is - as described in the release notes - the tool "nmtui" for the graphical setup of the network configuration.

Open

For more details about how to configure the static IP with nmtui see here. This is an example of how you can step by step configure a static IP for a Revolution Pi.

How to configure a Wi-Fi Network?

Here's a step-by-step guide for setting up WLAN, i.e. on the RevPi Connect 4 module

Option 1: Using the Terminal (nmtui):

1. Open the terminal

2. Type sudo nmtui and press Enter.

3. In the menu, select "Activate a connection" and then choose your Wi-Fi network.

4. Enter the Wi-Fi password when prompted.

Option 2: Using Terminal (nmcli)

1. Open the terminal

2. Set Your Country:

   sudo raspi-config nonint do_wifi_country DE

   • This command sets the Wi-Fi regulatory domain to the specified country (in this case, Germany - DE). It's important to configure this setting to comply with local regulations.

3. Check Wi-Fi Radio Status:

   nmcli radio wifi

   • This command checks the status of the Wi-Fi radio. It will indicate whether the Wi-Fi radio is enabled or disabled.

4. Enable Wi-Fi Radio:

   sudo nmcli radio wifi on

   • If the Wi-Fi radio is not already enabled, this command turns it on.

5. List of Available Wi-Fi Networks:

   • This command lists the available Wi-Fi networks in the vicinity along with their signal strength, security type, and other relevant information.

6. Connect to Wi-Fi Network:

   • Replace "YourWiFiSSID" with the name (SSID) of your Wi-Fi network.

   • This command prompts you to enter the Wi-Fi password. Once entered, it establishes a connection to the specified Wi-Fi network.

7. Replace "YourWiFiSSID" with your Wi-Fi network name.

8. Enter the Wi-Fi password when prompted.

Option 3: Using the Graphical Desktop Interface:

1. Click on the Wi-Fi icon in the top-right corner of the desktop.

2. A list of available Wi-Fi networks will appear.

3. Click on your Wi-Fi network and enter the password when prompted.

These steps should help you connect your RevPi Connect 4 to your Wi-Fi network.

Would it be possible to deactivate Wi-Fi communication permanently?

• Yes, take a look here

I am having difficulty establishing the Wi-Fi connection with the internal antenna, what am I doing wrong?

Switch to an external antenna by buying one. For example, take a look here:

Don’t forget to switch configuration as follows

Would it be possible to use RS485 as a serial console?

• Yes

Which Wi-Fi adapters are compatible with the 64-bit versions of the OS?

We have successfully tested those combinations

I am unable to connect the Wi-Fi of the RevPi Connect 4 to a 2.4Ghz band. Only 5Ghz. What can I do?

• Please check if the problem still occurs, if the external antenna is activated. Even without an antenna connected, the short pigtail can bring improvements.

• You can enable the antenna as following:

I have problems as soon as I activate both Ethernet and WLAN, and they are on the same networks, what can I do?

This may be a routing problem. Take a look at this part of Dirk's video tutorial where it is explained:
