16 bit service uuids in esp_ble_gap_config_adv_data

Postby jumjum123 » Mon Nov 20, 2017 3:36 pm

Is there a way to use 16 bit uuids for esp_ble_gap_config_adv_data ?
If not, whats the best option to convert 16 bit uuids to 128 bit uuid, is there any call in esp-idf ?

My notes seem to show that an esp_bt_uuid_t is a structure that contains a len field (ESP_UUID_LEN_16, ESP_UUID_LEN_32, ESP_UUID_LEN_128) and a union structure of either uuid16, uuid32 or uuid128. Thus when passing around service UUIDs, I think the intent is to pass around instance of esp_bt_uuid_t which also includes the size of the UUID as well as its value.
