Scan response with only a full device name returns NRF_ERROR_INVALID_DATA

[Marcel Mulder]

Hi,

I have created a scan response structure containing only the BLE_ADVDATA_FULL_NAME. This is because there in no room left in the advert data to advert the full name. The encode data looks good. The length (10) is correct and the type (9) is also correct followed with the device name which is 9 long. The only thing is that sd_ble_gap_adv_data_set() does not except this data and return NRF_ERROR_INVALID_DATA (11). I do not understand why because I do exactly the same thing on another BLE platform which works perfectly.

Can anybody telling me what I am doing wrong? I am using s110 7.1.0

Can you update the question with the return codes of the failing functions ?

[Marcel Mulder]

The return code is in the title: NRF_ERROR_INVALID_DATA (which has value 11)

It appears that you are doing the right thing, however I think the FLAGs AD type is a mandatory requirement in building the advertising packet, so add the flags AD type. Additionally mention the softdevice and the version number.

After setting the flags as I do in the advert data to BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE the error code returned is now NRF_ERROR_INVALID_PARAM (5) What do you mean with mentioning the softdevice and version number? The version I use (as already mentioned in the post) or do I have to add something in code?

I found the "problem". In the advert data I defined a short name. When I remove the short name in the advert data than I can use the full name in the scan response. I have to look up if this is a Bluetooth specification limitation or if this is a softdevice implementation limitation.
