nrf52 cc2650 advertising data empty

[Mickael]

Hello,

I have a nRF52 as central and a cc2650 as peripheral, when I received advertising answer, I can't see the full size of advertising data (see 7 instead of 31). With a smartphone (Sony Xperia) I can see advertising data and extract NAME etc ...

An idea ?

Thanks in advance

I think there is no clear consense of whether there have to be an empty advertising data (AD) at the end of the list, or not. Have you tried to add an extra '\0' to the end of your advertising data?

Note that some smartphone apps simply merge AD elements from passive (Adv. data) and active (Scan resp. data) into one list while on S13x/140 Soft Device API you will get two events and two buffers/strings. Also note that while 31 bytes is limit of standard Adv. or Scan resp. data buffers they are not padded to full length so if GAP layer sets shorter string they will contain less then maximum.

Hello,

This is a peripheral out of box, cc2650 Sensor tag. I will check for scan response data. Keep in touch.

Thanks for your help
