This rework sync_interval to be sync_factor as having sync_interval in
the order of seconds is sometimes not disarable.
Wit sync_factor the application can tell how many SDU intervals it wants
to send an announcement with PA, the EA interval is set to 2 times that
so a factor of 24 of BIG SDU interval of 10ms would look like the
following:
< HCI Command: LE Set Extended Advertising Parameters (0x08|0x0036) plen 25
Handle: 0x01
Properties: 0x0000
Min advertising interval: 480.000 msec (0x0300)
Max advertising interval: 480.000 msec (0x0300)
Channel map: 37, 38, 39 (0x07)
Own address type: Random (0x01)
Peer address type: Public (0x00)
Peer address: 00:00:00:00:00:00 (OUI 00-00-00)
Filter policy: Allow Scan Request from Any, Allow Connect Request from Any (0x00)
TX power: Host has no preference (0x7f)
Primary PHY: LE 1M (0x01)
Secondary max skip: 0x00
Secondary PHY: LE 2M (0x02)
SID: 0x00
Scan request notifications: Disabled (0x00)
< HCI Command: LE Set Periodic Advertising Parameters (0x08|0x003e) plen 7
Handle: 1
Min interval: 240.00 msec (0x00c0)
Max interval: 240.00 msec (0x00c0)
Properties: 0x0000
