struct bt_data ad[] = {
       
        BT_DATA_BYTES(BT_DATA_FLAGS, (BT_LE_AD_GENERAL | BT_LE_AD_NO_BREDR)),
        BT_DATA(BT_DATA_NAME_COMPLETE, dev_name, 18),
        BT_DATA_BYTES(BT_DATA_UUID16_ALL, 0x0D, 0x18),                      
        BT_DATA_BYTES(BT_DATA_UUID16_ALL, 0x0A, 0x18)                        
    };
   
    struct bt_data sd[] = {
        BT_DATA_BYTES(BT_DATA_UUID128_ALL,BT_UUID_NUS_VAL ),
        BT_DATA(BT_DATA_NAME_SHORTENED, short_name, strlen(short_name)),
    };

    int err = bt_le_adv_start(BT_LE_ADV_CONN, ad, ARRAY_SIZE(ad), sd,
                              ARRAY_SIZE(sd));

---------------------------------------------------------------------------------------------

dev_name=“YDB123E9C5FC872022”

short_name="YDB123E9C5"

but

in my prj.conf

CONFIG_BT_DEVICE_NAME="Zephyr"

Why is it displayed as not “YDB123E9C5FC872022”

My Android phone is displaying normally

Please give me some help

Hello,

If you have connected once to the device, the BT setting on the phone may cache the device name. The full device name might have been read during a previous connection, it's likely related to this if the advertisement packet only contain short name.
