Enabling USB debugging on the Fitbit Versa 4 without WiFi is challenging due to the device's specific requirements and limitations. Currently, Fitbit does not support third-party app development for the Versa 4, and there is no official SDK available for this model[7]. However, if you are trying to enable a feature similar to USB debugging for development purposes, here are some general steps you might consider, though they may not apply directly to the Versa 4:
1. Connect the Device: First, you would typically need to connect your device to a computer using a USB cable. However, for the Versa 4, this process is not straightforward due to the lack of support for USB debugging as seen in Android devices.
2. Access Developer Options: On devices that support USB debugging, you would typically go into the settings, find the "About" section, and tap on the build number several times to unlock developer options. However, the Versa 4 does not have this capability in the same way Android devices do.
3. Enable USB Debugging: Once developer options are available, you would look for the "USB Debugging" option and toggle it on. For the Versa 4, there is a setting called "Developer Bridge/USB Debugging," but users have reported issues with enabling it properly[7].
Given the limitations and issues reported with the Versa 4, it seems that enabling USB debugging as you would on an Android device is not feasible. The Versa 4's developer bridge feature is intended for testing apps, but it appears to be malfunctioning or not properly supported[7].
If you are looking to develop apps for the Versa 4, you should consider reaching out to Fitbit's developer community or forums for more information on potential future support or workarounds. Currently, there is no straightforward method to enable USB debugging on the Versa 4 without WiFi, and the device's development capabilities are limited compared to other platforms like Android.
