| 73 | This data can include the device name, GATT services offered by the device, and so on. |
| 74 | The data set via this class will be used when advertising is started by calling |
| 75 | \l QLowEnergyController::startAdvertising(). Objects of this class can represent an |
| 76 | Advertising Data packet or a Scan Response packet. |
| 77 | \note The actual data packets sent over the advertising channel cannot contain more than 31 |
| 78 | bytes. If the variable-length data set via this class exceeds that limit, it will |
| 79 | be left out of the packet or truncated, depending on the type. |
