@xiong.zhang thanks for you reply.
In my scenario khadas vim3 will always get connected to a Ethernet / WiFi for data connectivity (high speed) and my Bluetooth controller app hosted on other android phone may or mayn’t have high speed network connection which is impacting data connectivity of vim3 board that’s my issue.
one more bug we are facing is kvim3 board loaded with aosp9 is getting connected with android 10 or below versions and iphone via bluetooth tethering but for android 13 and higher versions it is not getting connected which ever way we are trying.
(for this I made a video but cannot upload it here)
Note:
I went through this link Device wrong network priority 4g > LAN, but in my code NETWORK_SCORE is kept to 70 only but still Bluetooth tethering is affecting my ethernet network or external wifi connectivity.
