      Code (inc. data)   RO Data    RW Data    ZI Data      Debug   

     23476       1898        416        280       3864     508922   Grand Totals

==============================================================================

    Total RO  Size (Code + RO Data)                23892 (  23.33kB)
    Total RW  Size (RW Data + ZI Data)              4144 (   4.05kB)

Hello sir,

will you tell me one thing that can we use direct read write functions in esb_prx function?

and also tell me that the fds example you had told that is working in sdk 11.0.0.i had tried that example its working fine in sdk 11.0.0. then i have tried by adding fds library in my main code i.e in ble_app_uart in sdk 12.2.0 added all fds function calls i.e write ,fds_read() on my ble_app_uart i had added the fds code same as added in the proximity example. compiled my project with 0 errors.but i noticed that in my fds code the fds_init() function executes continuously.it will not going on the next loop. i am not understanding why it is happening.

so my main question is that can we use fds in only sdk 11.0.0. or it can be used in sdk 12.2.0.

Thank you
