HI
my Version: SDK15.3,ble_app_template,custom board with nrf52832
I'm trying to load device name from fds when initial,
my goal is sending message to my board to change the device name ,and use fds_record_update to update the name in fds
It works few hours ago,but is not working now
I think maybe something interrupt the fds_record_update or something weird happened
PS. I didnt initial FDS,because it seems that peer_manager_init() in ble_app_template has already do that for you ,so i dont have a fds_evt_handler
PS 2. I follow the tutorial:https://devzone.nordicsemi.com/nordic/short-range-guides/b/bluetooth-low-energy/posts/ble-services-a-beginners-tutorial
so I wrote our_fds.h,our_fds.c independently for using them in our_service.c!
below is fds.c

massage from bluetooth is data in log
DD DD is id
4 is lenth
41 42 43 44 is ABCD
and I concade it to GT06_ABCD
no error from fds_record_update

Any help is appreciated. Thanks.
