I was talking about scan response packets. Fortunatelly, I did what I want, placing my data inside manufacturer specific data structure.

We are talking about advertising packets? If you want to stay BLE compliant, you should format the packets as proper advertising packets. For this reasonsd_ble_gap_adv_data_set() will check the format of the packet, as you can see from the API documentation.

One more question, should I encode the date in the same way as advertising data or can I send bunch of my data in the way I want? I mean if I have to use the structure ble_advdata_t

You can always make subsequent calls to sd_ble_gap_adv_data_set() with another set of data. (The const indicate that the function will not change the array you supply, not that you cannot update it and call sd_ble_gap_adv_data_set() again).

There is no event in the current SoftDevice that indicate that an advertising event has occurred. However, you can use Radio notification to be notified every time the radio is used, and change the advertising data at that time. If your device does not have any connection, the only radio TX activity will be due to an advertising event.
