Adding custom service to USER_ADVERTISE_DATA
Posted byozgurkoc35 points 4 repliesHi all,
I have a DA14531-00FXDEVKT-U (Development Kit-USB). I want to add custom service to USER_ADVERTISE_DATA. First of all, I achieved to add User Data Service by following the steps on this link (https://support.dialog-semiconductor.com/forums/post/dialog-smartbond-bluetooth-low-energy-%E2%80%93-software/add-bass-service-bleappota) and it worked without any problems. But for example i want to add a custom service with UUID: 00112233445566778899AABBCCDDEEFF. How can i add? If I can't add, why can't I add it?
accepted answer!

Hi ozgurkoc,
Thanks for your question. You try this one :
/// Advertising data #define USER_ADVERTISE_DATA ( "\x11"\ ADV_TYPE_COMPLETE_LIST_128BIT_SERVICE_IDS\ "\x00\x11\x22\x33\x44\x55\x66\x77\x88\x99\xAA\xBB\xCC\xDD\xEE\xFF")Thanks, PM_Dialog

Hi ozgurkoc,
You can check this tutorial :
http://lpccs-docs.dialog-semiconductor.com/DA145xx_Advertising_Tutorial…
The 0x11 indicates the length, so ADV_TYPE_COMPLETE_LIST_128BIT_SERVICE_IDS plus the UUID has 0x11 length.
ADV_TYPE_COMPLETE_LIST_128BIT_SERVICE_IDS (=0x07) is the tag : Complete list of 128-bit Service IDs
Thanks, PM_Dialog
