    I assume that you are talking about the Bluetooth core specification. The Link Layer specifies the on air interface (complete packet including preamble, access address, pdu and CRC) while GAP specifies the AdvData part of the PDU (AD structure and AD types...)

    For usage with the S110 softdevice, see Advertising Data Encoder and sd_ble_gap_adv_data_set. Or simply look at advertising_init in one of the SDK examples
