Forerunner 235 latest SDK compatibility

I am developing some watchfaces for my Forerunner 235 and I can see the ConnectIQ version on it is 1.4.5 while the latest SDK version is 3.x. Is Forerunner 235 compatible with 3.x? If not, is it 1.4.5 the latest version it is compatible with? Where can I find an API for 1.4.5? The 3.x API is confusing as some of the functions are not working. Thanks!

  • The 3.x SDK that you downloaded can be used to build apps for older devices. The simulator *tries* to accurately represent what features the devices actually support, but it isn't perfect.

    You should be able to look at the documentation and see what SDK version added each API feature. For example, the Background module was added in 2.3.0, so devices that don't have support for the 2.3.0 SDK won't be able to use that module.
