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!
