Compatibility
Which apps and radios work with SD-Link?
SD-Link connects your radio to your navigation app via Bluetooth Low Energy. Here you can see at a glance which apps are supported and for which radios there is a suitable plug-and-play solution.
Navigation apps
Overview of supported apps
Whether frequency transmission is available depends on the app, operating system, and radio protocol. The following overview shows the current status. The step-by-step process of sending frequencies from SkyDemon to the radio is explained below.
Currently only supported for ATR833 and KRT2.
Support in development.
Not compatible: ForeFlight does not allow third-party Bluetooth LE devices (statement from ForeFlight Support, 09/2025). Our adapters use an open Bluetooth standard; the decision rests with ForeFlight.
Not yet compatible: SDVFR does not have a Bluetooth connection to the radio. We have offered our support to the developer.
Not compatible: Garmin does not open the interface for devices from other providers.
