There are several known issues related to the Fitbit Versa 4, but specific information about using SDK5 for this device is limited. Here are some key points regarding the Versa 4 and its development environment:
1. SDK Compatibility: The Fitbit Versa 4 does not have an official SDK available for developers. The Versa 3 SDK is not compatible with the Versa 4, and there are no plans for a Versa 4 SDK release. This means that developers cannot create or download third-party apps or clock faces for the Versa 4 using the current development tools[3][4].
2. USB Debugging Issues: Users have reported difficulties with enabling USB debugging on the Versa 4. Despite the option appearing in the settings, selecting it does not activate debugging mode properly, suggesting a potential bug in the OS[3].
3. Syncing Problems: Many users have experienced syncing issues with the Versa 4, often requiring restarts of both the watch and phone, or even factory resets. These problems can be exacerbated by updates or connectivity issues[1][5][9].
4. Accuracy and Functionality Issues: Some users have reported inaccuracies in step tracking and other fitness metrics, as well as disappointment with the device's limited functionality compared to previous models[6][8].
5. Developer Bridge and Simulator: The Versa 4 does not have a simulator available for testing apps, which complicates development and debugging processes. Developers are advised to use the Versa 3 SDK and simulator for development, then adapt their work for the Versa 4 through manual testing[4].
In summary, while there isn't specific information about SDK5 for the Fitbit Versa 4, the device faces several challenges related to development and user experience. The lack of an official SDK and issues with syncing and functionality are significant concerns for both developers and users.
