How to add custom UUID as part of BLE Advertisement packet

Hi Deepa

Don't use BLE_UUID_TYPE_VENDOR_BEGIN, register the UUID you need with sd_ble_uuid_vs_add() and use the return from that function as MY_UUID_TYPE

I don't know where the practice of trying to use that constant came from, it's always been wrong.

Best regards,

Simon

Hi Simon,

Thanks for the reply.

init.advdata.uuids_complete.uuid_cnt = sizeof(m_adv_uuids) / sizeof(m_adv_uuids[0]);
init.advdata.uuids_complete.p_uuids = m_adv_uuids;

The above initialisation is already taken care in Nordic SDK ble_app_gls Example, at advertising_init().

It works only for BLE SIG UUID but it is not working for Custom service UUID?

Thanks & Regards,

Deepa

Hi Deepa

You should be able to advertise your UUID by adding the following to your advertising init():

advdata.uuids_complete.uuid_cnt = sizeof(m_adv_uuids) / sizeof(m_adv_uuids[0]);
advdata.uuids_complete.p_uuids = m_adv_uuids;

Best regards,

Simon
