The MCU is NRF54L10, the SDK is NCS2.9.1, and the firmware is updated using MCUboot update mode.
Configuration as follows：
# sysbuild.conf
SB_CONFIG_BOOTLOADER_MCUBOOT=y
# prj.conf
CONFIG_NCS_SAMPLE_MCUMGR_BT_OTA_DFU=y
When updating firmware using the nRF Connect Device Manager mobile app, I encountered the following issues:
1. After the update, sometimes some functions of my device are abnormal, while others are normal. A reset is required for all functions to work correctly (this problem doesn't occur every time after an update, it happens occasionally). I would like to know the reason for this.
2. After my device is flashed with firmware via J-Link, the first time it connects to the phone and I try to update the firmware using nRF Connect Device Manager, the update fails to start. After a few seconds, the phone displays a "connection timed out" message, requiring me to disconnect. After reconnecting to the phone, the firmware update can begin. It seems that after flashing firmware via J-Link, a connection to the phone is required to complete pairing information exchange before subsequent connections can initiate firmware updates. However, I don't have a pairing function set up in my software. What could be the reason for this?(This problem can be reproduced 100%)
