Using the developer bridge on the Fitbit Versa 4 without WiFi is theoretically possible through USB debugging, but it appears to be problematic and not fully supported at this time. Here's a detailed overview:
1. Enabling Developer Bridge via USB:
- To attempt to use the developer bridge without WiFi, you need to connect your Versa 4 to a charger and access the settings menu. Navigate to the Developer Bridge option and toggle on USB Debugging**[1][5][7]. However, users have reported issues with this process, such as the screen turning off without restarting or Fitbit Studio not recognizing the device[1][5].
2. Limitations and Issues:
- The Versa 4 does not support WiFi for developer bridge connections, which were common in earlier models like the Versa 3[1][3]. This shift to USB debugging might be intended to reduce battery drain, but it seems to be a new process that is not fully developed or supported yet[3].
- Fitbit Studio, the platform for developing and testing apps, does not currently support connections from the Versa 4, which complicates the development process[3].
3. Future Support and SDK Availability:
- As of now, there is no official SDK available for the Versa 4 or Sense 2, which means third-party developers cannot create or install custom apps or clock faces on these devices[1][3]. Users have been advised to wait for future SDK releases or provide feedback to Fitbit to support these features[1].
4. Workarounds and Alternatives:
- Some users have suggested using Bluetooth for potential developer bridge functionality, but this is speculative and not confirmed[3]. For now, there are no reliable workarounds for using the developer bridge without WiFi on the Versa 4.
In summary, while it's theoretically possible to attempt using the developer bridge via USB on the Versa 4, the process is not reliable, and full support is lacking due to the absence of an official SDK and WiFi connectivity.
