Update Device

Open Settings on Rand/0.

Select Wi-Fi OTA.

The device will use the last saved Wi-Fi network to perform the OTA update.

During the update, make sure the network connection is stable and do not power off the device.

Use Another Wi-Fi Network

If you need to use another Wi-Fi network for Wi-Fi OTA, add that network first:

Open Settings.

Select Wi-Fi Time Sync.

Follow the on-device prompts to complete network setup.

After setup is complete, this Wi-Fi network can be used for Wi-Fi OTA.
