Logging data in nrf51822

Hi,

I am reading some data from an accelerometer using the nrf51822. Now i would like to save this data offline in the nrf51822 itself, and after i have some data send it to my android app.

The problem is that i couldn't find a way to store this data in the nrf51822 (Flash). I thought that one way to do it is to save the data in a kind of .csv format so then i could download it through the app and read it but i couldn´t find any example about data offline-logging. A second option would be to use the LOG() functions to save data, but then i couldn´t find any way to download that info through my app. What would be the best way to do it? Is there any example code for doing it?

Thank you,
