I currently have a self-developed 5340 development board, using the Bluetooth transparent transmission routine. These are my current main.c file, device tree file, and configuration file. When debugging the program, it gets suspended after entering `err = bt_conn_auth_cb_register(&conn_auth_callbacks);` in the main function. What could be the reason for this? Please help me.
