After reading this page: http://developer.samsung.com/gear/develop/tech-doc/Tizen-Studio-for-legacy-Gear-devices I noticed that the GearS and other old smartwatches are not compatibel with V2.3. They say its still possible to build webapps for the GearS if I change my Version in the configfile.xml.. but it doenst give the option to select V2.2 that covers all the old Tizen versions.
If someone has an answer for me where I can make apps for GearS and the api for making apps it will be great. The current web api supports V2.3 and above.
