Zephyr UUID compiled warning

[ZL_Chiu]

Hi  

I use different UUID setting , setting 2 on any compiled warning , but setting 1 has compiled warning .

below is UUID:

setting 1 :  

    #define BT_UUID_CUSTOM_SERVICE_VAL BT_UUID_128_ENCODE(0x00010000, 0x452d, 0x4269, 0x6b65, 0x000061636572)

    static struct bt_uuid_128 vnd_uuid = BT_UUID_INIT_128(BT_UUID_CUSTOM_SERVICE_VAL);

    static const struct bt_uuid_128 MEASUREMENT_uuid = BT_UUID_INIT_128(BT_UUID_128_ENCODE(0x00010001, 0x452d, 0x4269, 0x6b65, 0x000061636572));

    static const struct bt_uuid_128 INFORMATION_uuid = BT_UUID_INIT_128(BT_UUID_128_ENCODE(0x00010004, 0x452d, 0x4269, 0x6b65, 0x000061636572));

    static const struct bt_uuid_128 CTRLPT_CHAR_uuid = BT_UUID_INIT_128(BT_UUID_128_ENCODE(0x00010010, 0x452d, 0x4269, 0x6b65, 0x000061636572));

    static const struct bt_uuid_128 CTRLPT2_CHAR_uuid = BT_UUID_INIT_128(BT_UUID_128_ENCODE(0x00010011, 0x452d, 0x4269, 0x6b65, 0x000061636572));

setting 2:

     #define BT_UUID_CUSTOM_SERVICE_VAL BT_UUID_128_ENCODE(0x00010000, 0x452d, 0x4269, 0x6b65, 0x58706c6f7661)

     static struct bt_uuid_128 vnd_uuid = BT_UUID_INIT_128(BT_UUID_CUSTOM_SERVICE_VAL);

    static const struct bt_uuid_128 MEASUREMENT_uuid = BT_UUID_INIT_128(BT_UUID_128_ENCODE(0x00010001, 0x452d, 0x4269, 0x6b65, 0x58706c6f7661));

    static const struct bt_uuid_128 INFORMATION_uuid = BT_UUID_INIT_128(BT_UUID_128_ENCODE(0x00010004, 0x452d, 0x4269, 0x6b65, 0x58706c6f7661));

    static const struct bt_uuid_128 CTRLPT_CHAR_uuid = BT_UUID_INIT_128(BT_UUID_128_ENCODE(0x00010010, 0x452d, 0x4269, 0x6b65, 0x58706c6f7661));

    static const struct bt_uuid_128 CTRLPT2_CHAR_uuid = BT_UUID_INIT_128(BT_UUID_128_ENCODE(0x00010011, 0x452d, 0x4269, 0x6b65, 0x58706c6f7661));

Hello,

Sorry for the late reply. We have a bit of backlog since the public easter holiday last week. 

I am not able to reproduce what you are seeing. What NCS version are you using? And could you zip your application folder so that I can try to replicate it?

These compiler errors can be a bit difficult. Could it be that you changed something else when changing between the two?

Best regards,

Edvin

Hi 

Base NCS v2.4.2 .

don't changer another code , just change settting.

[Edvin]

There are hundreds of samples in NCS v2.4.2. Can you please specify what sample you are trying to build, and how to reproduce the issue that you are seeing? 

BR,
Edvin
