What to do if the Xiaomi Offline Communication fails to connect?

If both your device and the other party's device meet all the requirements for using Xiaomi Offline Communication, but the feature still doesn't work properly, it's important to understand that wireless calling primarily relies on a stable wireless signal.
Please refer to the following troubleshooting steps:
1. Keep the physical distance between devices within the official effective range.
2. Make sure neither device is in Battery saver mode, as it can weaken the signal.
3. Move to an open, clear area (avoid walls, furniture, or dense obstacles that block signals) and stay away from places with high electromagnetic interference.
4. Retry connecting after a short wait to avoid temporary signal fluctuations.
5. Restart both devices to refresh the wireless connection and fix temporary software glitches.
