Jason,
Sorry for the delay in joining this discussion group. The Sonoptix ECHO is under our BlueLink umbrella and “we” have been quietly improving the capabilities of the unit as well as working to provide the API/SDK. The API package is currently available and the SDK should not be too far away from a beta release with a couple test partners. If you’d like to receive the API package, please send an email to jeff@blue-linked.com.
I’d like to add that we just released software update 1.2.0 which adds some nice new features and extends the maximum range to 200m. Please got to https://sonoptix.com/software-updates for more info and the file download.
