Sportablet 5.7 and the Uploader for Garmin 4.7 have been fixed to work with the new release of the Radio Service. However, while I managed to keep the previous version compatible with versions 2.x, 3.x and 4.0 of the Radio Service, this is proving too complex, and is causing every version of the Dynastream driver to break my apps. Therefore, beginning from this version, I'm only supporting the Dynastream ANT+ Radio Service version 4.01 (4.1). Of course, while I hope they won't break it again in the next release, I'll always do my best to update the app if anything happens.
Short story: if you get the new ANT+ service, you need the new app; if you get the new app, you need the new ANT+ service.
