Advertising packets
Packet reguarley broadcast by the advertising device (peripheral).
manufacturer_data
Can be used for custom data bytes for your particular application.
BLE scan response
Packet sent by the advertising device (peripheral) upon the reception of scanning requests (it is a response to a device scan). Typically has more data than the advertising packets – devices send scan requests to the advertising device in order to get additional user data through the scan response.
Scan responses are considered to have fixed ‘static’ data (relative to the more dynamic advertising data).
Advertising packets and scan response share the same format, and are transmitted over the same channels (they are both sent as advertising events), but are otherwise two different things.
