https://devzone.nordicsemi.com/f/nordic-q-a/21575/fds-problemHello, What I want to do is to store custom data to flash using FDS in &quot;disconnected&quot; event. When I try to write the data in &quot;disconnected&quot; event, the write_flag is never raised. Is there any solutions to help me to solve this problem?
