Hi,
I am facing an issue while integrating BLE with the rest of my code. The code crashes when I try to start BLE outside of main().
Currently, I have placed the BLE initialization at the beginning of main(), and it starts and advertises successfully. However, the code crashes during the bonding process.
- I am using two threads in my application.
I am using nrf5340, 2.6.1 SDK and 2.6.1 toolchain manager.
This are my configuration.

this is BLE start code
int BLE_Start()
{
int err;
err = bt_enable(NULL);
if (err) {
LOG_ERR("Bluetooth initialization failed (err: %d)", err);
return err;
}
LOG_INF("Bluetooth initialized");
err = bt_nus_init(&nus_cb);
if (err) {
LOG_ERR("Failed to initialize NUS service (err: %d)", err);
return err;
}
LOG_INF("NUS service initialized");
bt_conn_cb_register(&connection_callbacks);
bt_conn_auth_cb_register(&conn_auth_callbacks);
bt_conn_auth_info_cb_register(&conn_auth_callbacks_info);
LOG_INF("Bluetooth callbacks registered");
if (IS_ENABLED(CONFIG_SETTINGS)) {
err = settings_load();
if (err) {
LOG_ERR("Settings load failed (err: %d)", err);
return err;
}
LOG_INF("Settings loaded");
}
return 0;
}
Please help me resolve this issue, as I am in the final stage of my project completion!
