Here is my advertising_init function. Looking at it,it appears i wrap the UUID i am looking for in srdata and the manuf data in advdata and then encode those separately. Are these encode advertising packets you speak of?

I am looking for the TB_UUID_SERVICE and parsing the packet with that information. However it appears the manufacturing data appears in the packet with the m_adv_data[0] UUID.

Hello,

It may be that the UUIDs and the manufacturer data are not present in the same advertising packets. If the manufacturer data or the uuids are in the scan response, and the other is in the "normal" advertising packet, these will be two different advertising reports.

How is the advertisement set up in the peripheral?

Best Regards,

Edvin
