How can i save my vitals data in my custom fitbit wearable app?

I developed a wearable app that syncs my vitals info with the Fitbit companion app. All i want is, when the connection breaks all my vitals info saved in my wearable app and when next time connection establishes all my saved vital info syncs with Fitbit companion app.

I'd recommend persisting the data to the device using CBOR https://dev.fitbit.com/build/guides/file-system/

Then transferring that to the companion using the File Transfer API https://dev.fitbit.com/build/guides/communications/file-transfer/
