Perhaps the most requested feature from the sysadmin community was safety. Beta 2 introduces a comprehensive pre-flight check. Before a single firmware packet is sent, the tool queries the target devices to verify free flash space, battery status (for IoT devices), and current uptime. It will automatically quarantine devices that do not meet the stability criteria, preventing them from entering the upgrade cycle.
The host PC must be set to a specific static IP address (often 192.168.1.100 or 192.168.8.100 ) to communicate with the hardware's bootloader.
