How to get full Service UUID from given BASE UUID

[davidm]

Hi all

I am trying to pair nrf52840 (as a central) with ESP32 (as peripheral).

 Now I want to get the service uuid so that i can pass to advertising service in ESP32 code.How do I get the full-service UUID, I see that in the ble_lbs_c service  UUID is declared as 0x1523 characteristic  UUID as 0x1525 and LBS_UUID_BASE {0x23, 0xD1, 0xBC, 0xEA, 0x5F, 0x78, 0x23, 0x15, 0xDE, 0xEF, 0x12, 0x12, 0x00, 0x00, 0x00, 0x00}

I tried to pass the service uuid as #define SERVICE_UUID   "23151212EFDE1523785FEABCD1" on ESP32 program but that didnt work. What is the exact order of the UUID? If you need  details on esp32 code here is the example esp32 program

I am using ble_app_blinky_c example on nrf52840.

Thank you in advance

Hi Edvin

My mistake, I meant to say ...it does get inside name_filter_enabled but  adv_name_compare(p_adv_report, p_scan_ctx)is always false.

It was a copy/paste  error.

Ok. Then you need to debug it when you know it is the correct device, and find out why it returns false.

One hint when debugging is to apply a second filter before adv_name_compare is called, if you know something else about this specific device. If you know that the address starts with e.g. 0xb5, then you can do a check:

if(p_adv_report-> ... .addr[0] == 0xb5)
{
    adv_name_compare();
}

Why does it not return true?
