After I flash my code,I get imformations as follow:

I can not understand it.Maybe about settings_load()?

The main function in my code as follow:

int main(void) int主要(空白)

  int err; int犯错;

  uint32_t blink_status = 0;

  struct dm_init_param init_param; struct dm_init_param;struct dm_init_param;

  err = dk_leds_init(); 错误 = dk_leds_init（）; 错误 = dk_leds_init（）;

  if (err) {

 printk("LEDs init failed (err %d)\n", err); printk(" led init failed (err %d)\n"， err);printk(" led init failed (err %d)\n"， err);

 return 0; 返回0; 返回0;

  }

 

  err = peer_init();

int main(void)

	int err;
	uint32_t blink_status = 0;

	init_param.cb = &dm_cb;

	err = dm_init(&init_param);
	if (err) {

	}

	err = service_ddfs_init();

	}

	char *name = namecat();
	err = bt_set_name(name);

Thanks. The error suggests that your 'name' array is too small to hold the concatenated name. I don't know the length of your DEVICE_NAME string, but do you see the same issue if you increase the array to, let's say, 30 bytes instead of 18?

[Chaoyue Ying]

Thanks,it seem the length short due to the issue.But there still a little problem that the length of string is default plus one to accommodate a finish flag '\0'?The follow string display char[15] when my mouse stop over it.

#define DEVICE_NAME             "Anny_AutoDoor_"

[Vidar Berg]

Yes, the string will be terminated with null, so the size of the array will be the number of characters + the '\0' character.
