nRF52810 Advertising data location

[Kasper Leonhardt]

Hi Nordic

I am porting an application from the EM9304 SoC to the nRF52810.

In the old application it was possible to send 26 bytes of manufacturer specific data (plus field ID and length) plus a 10 character name and a two byte service UUID.

Data captured bu a BLE scanner:
{
  kCBAdvDataIsConnectable = 1;
  kCBAdvDataLocalName = Candymaker;
  kCBAdvDataManufacturerData = <00000100 ffeeddcc bbaa0200 ffeeddcc bbaa0300 ffeeddcc bbaa>;
  kCBAdvDataServiceUUIDs = (
    1802
  );
}

Quick calculation tells us that it takes more that 31 bytes. That meens that it cannot be included i a single advertising packet.

But how is it solved on the EM9304? Is the Scan Responce packet used for the manufacturer specific data?

I have tried to change the location of the manufacturer specific data (Changeing the ble_advertising_init function) but the softdevice returns "wrong parameter".

Do you have any clues?

Hey Kasper,

You need to change the advertisement data before calling ble_advertising_init. See the ble_advdata_t advdata and srdata members of ble_advertising_init_t.

Cheers,

Håkon.

Works. I did not know that there was a placeholder for manufacturer specific data in the srdata structure. Easy one :-)

I'm glad to hear Kasper,
Happy coding! :)
