Agent on ZEBRA TC56 disconnects itself
Doze mode is probably enabled still. Try disabling Doze mode.
This helps on these devices.
Does anybody know, why the agent keep the connection on hundreds of devices without disabling the doze mode, but on a view devices not?
There's likely no telling. Doze mode and now Adaptive Battery Use leverage AI to determine which applications should be throttled based on their usage patterns. It really has no place in the enterprise world with hot-swappable batteries so I always disable it for our dedicated device deployments.
