Extended Advertising example

[Damien Berger]

Hello,

I am trying to use the extended advertising mode available on the V15 of the SDK (with SD S140 V6.0.0). I use the template example where i am currently advertising a manufacturer data. I would like to be able to advertise a bigger manufacturer using extended advertising.

I read in the release note that i have to use one of the extended advertising types such as "BLE_GAP_ADV_TYPE_EXTENDED_NONCONNECTABLE_SCANNABLE_UNDIRECTED".
I don't know where to use it, i tried in ble_advertising functions but it didn't work.

How can i do that ? 

Do you have an example using extended advertising ?

Hi Damien,

Were you able to find a way to advertise larger packets yet?

I am trying to accomplish the same thing you are, and seem to be finding that SD S140 V6 does not fully support the advertising extensions. More specifically, my packets are being limited in size. I suspect that the BLE_GAP_ADV_SET_DATA_SIZE_MAX is being used for the extended advertising packets as well, so the SD is only allowing for 31 bytes to be sent.

My sniffer shows the packet being truncated if I try to send more data. I don't fully understand the extensions yet, but I think a CHAIN packet is supposed to follow with more data if the packet was truncated.

Can anyone at Nordic provide some feedback about these observations?

Hi, yes it comes from my boards revision (Eng. A) which does not support extended advertising.
