Frequently Asked Questions

We have seen issues after updating the firmware causes your Kestrel to disconnect frequently. The fix for this seems to be just restarting your mobile device. After restarting the mobile device, try connecting again to the new Kestrel LINK app

Any time you connect to the Kestrel LiNK app on your mobile device, it will automatically check for any firmware updates. If it does not prompt you for a firmware update, then you have the latest version.

You can connect the HUD to the Kestrel LiNK Ballistics app for iOS or Android and update the firmware that way. When you connect, you will be notified that an update is available. The HUD would need to be turned on and have Bluetooth ON in order for the Ballistics app to find it and connect to it. There is no other functionality for connecting the HUD to the application except for updating firmware
