[Enhancement] Set the connection profile for AP mode to -999

[SBCV-apegram]

As a way to keep the configuration access point available in case there is no known Wi-Fi network or wired network, you can set the WIFI_AP connection priority to -999. That way, it doesn't need to be deleted when adding new network credentials. If no known networks are found, the player will automatically broadcast the configuration AP. If a user doesn't want a fallback AP to be broadcast, there could be a checkbox in the admin console to set the connection.autoreconnect property to no.

If this isn't baked into a future image, you can accomplish something similar with the following commands run in ssh (tested on Raspberry Pi 5 running the 5.3.5 image):

sudo nmcli connection add con-name Fallback type wifi mode ap ifname wlan0 ssid $HOSTNAME connection.autoconnect-priority -999 wifi-sec.key-mgmt wpa-psk wifi-sec.psk piplayer 802-11-wireless.band bg 802-11-wireless.channel 6 ipv4.method shared ipv4.addresses 192.168.100.1/24 ipv6.method disabled

This isn't affected by any of the pisignage scripts (it's treated like any other network profile), but I don't know if it will persist through updates. The Wi-Fi name will be the hostname of the player, and the password is piplayer. If there are no known networks in range, this SSID will broadcast allowing you to add a new Wi-Fi network.

Thanks! we will incorporate this in future images.

Thanks! While you're at it, it might be useful to add the following script to shut off wi-fi when wired networking is detected:

#!/bin/bash
 export LC_ALL=C

 enable_disable_wifi ()
 {
     result=$(nmcli dev | grep "ethernet" | grep -w "connected")
     if [ -n "$result" ]; then
         nmcli radio wifi off
     else
         nmcli radio wifi on
     fi
 }

 if [ "$2" = "up" ]; then
     enable_disable_wifi
 fi

 if [ "$2" = "down" ]; then
     enable_disable_wifi
 fi

Just name this script 70-wifi-wired-exclusive.sh and place it with executable permissions in the /etc/NetworkManager/dispatcher.d/ directory, and NetworkManager will take care of it automatically.

We have implemented the first comment in 5.4.0 image (yet to be released), once again thanks for helping us! Not implementing the second request as we have users who use Cellular modem (eth0) and wifi at the same time (they download content only wifi is available!)

Thanks! I look forward to that be feature.

As to the script in my second comment, would it be possible to have that as an option in the admin console? A checkbox that activates the script when checked and deactivates when unchecked?
