Hey, I am using a mediatek device running rooted android 4.4. I am using M2M sim cards with private APN, private static IP and global roaming plan. Each of my sim have its own static IP. I can therefore ping them from my server on the VPN. But few minutes/hours after boot, devices becomes un-addressable. If I try to ping it from the server, I got no answer. sometimes it is only after 2 minutes! The only way to put the device addressable again is to send a packet from the device to the server
Questions: - How can I avoid this? - Is is possible to detect that the device is not reachable? If I have a look at `adb shell netcfg` the device always have an IP, even when it is un addressable from outside. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
