Is it possible to read/show the sensor data on mobile application during ActivityRecording?

I tested if it's possible to save raw accelerometer data and gyroscope data at a max sampling rate(25 or 50Hz). And it was not possible making "out of memory for FIT data".

So, I'm thinking kinda like this:

1. Start ActivityRecording on Garmin watch(forerunner 255)

2. Send sensor data to a mobile application using Bluetooth (if possible)

3. Save the data in the mobile application's storage.

I want to know if this is possible or if not, is there any idea that i can do what i want?

Thank you for reading.
