Logging of accelerometer and gyroscope data and saving to file

in Android

Good morning everyone,
I am new to the mbientlab sensors and I am implementing an Android application which, upon connection with the METAMOTIONR sensor, logs 10 minutes of data from the accelerometer and gyroscope modules. At the end of the 10 minutes I want to download the data and save it to two different files, one for each module. Is this possible? I saw that the offcial metabase application offers this option but, following the documentation, I wasn't able to reproduce the functioning.
If anyone is able to show me where to look to find example code I would be very grateful!
Thank you,
Silvia

    There is example code on GIthub.

    Thank you for mentioning it, I could only find an example that logs ONE of the modules at a time (only accelerometer). What I am having trouble with is logging two on two different files, and saving them. Could you point me to the example you mentioned?
    Thank you so much,
    Silvia

    Look at an example that streams data for two sensors and copy the same logic for logging.
    You got this, just go through our tutorials and code what you need.

    Thank you so much I will try it. What I still cannot find is how to save the data that I download with logging.downloadAsync function. I am able to download it but not to access this download and therefore save it. Is there any example code for this part as well? From the freewill application example I see it prints part of the logged data related to the freewill events but I wasn't able to reproduce it with ALL the accelerometer and gyroscope logs.
    Thank you,
    Silvia
