About development using charge 4

[leeyd]

Is it possible to develop an app that acquires acceleration data using charge 4?

Can you tell me the Fitbit device and API needed to get the acceleration data and work with the Android device?

Charge 4? No. You need Ionic, Versa (any) or Sense.

Getting accelerometer data from the watch to an Android device is possible, but difficult.

Thanks you.

I found the Accelerometer API from Reference, but I can't see the API for transferring Accelerometer data to an Android device.
Do you not offer?
For example)
・ Saving Accelerometer data in Local Storage and transferring it to an Android device
・ Transfer Accelerometer data live using Bluetooth

You have to use messaging or file transfer to send data from watch to companion.

You have to use fetch() or websocket to send data from companion to a server (which could reside on your Android device).

You can't directly exchange data between your Fitbit device and your Android device, you can only use the API to go through the server, right?

Thank you very much.

That's right, although you can host a server on your Android device.

Like I said, it's difficult. 🙂
