Firmware updates are a delicate operation that transmits system files directly to the ring via Bluetooth (BLE) communication. If errors occur during the update, set up the following conditions and try again.

1. Ensure sufficient battery: If power is cut during an update, fatal errors can occur on the device. Charge the ring to at least 50% or safely place it on the charging dock so power is supplied during the update.

2. Maintain close proximity and reduce interference: Until the update is complete, place the smart ring and smartphone right next to each other (essentially touching) and don’t move them. Briefly turning off other nearby wireless devices (Wi-Fi, Bluetooth devices, etc.) can reduce wireless interference.

3. Keep the app on screen: While the update is in progress, never close the b.ring app or switch to the background (going to the home screen, opening other apps). If the smartphone screen turns off, communication may be cut off, so keep the screen on.
