Why Connect Core 6 in android fails to open eth0? using a FTPClient and UDP Server android app.

The android ftp client can connect only when using wlan0. E.g. Connecting to a web hosted ftp server.

However when using the eth0 (LAN interface) android doesn’t see any connectivity I.e can’t find the eth0 interface.
Thus it can’t connect to the FTP Server.

The app permission are set properly is not a matter of permission access.

are you using stock images? Static IP? DHCP? Ethernet is enabled in Android Settings and WLAN is disabled? seems to work well here for me.

Yes I’m using the stock image. I finally traced the problem. You must enter a value in the dns1, dns2 fields. By default these are empty when setting a static Ip address. Thanks.
