Formula for extended advertising interval set by kernel for Bcast: interval = (qos->bcast.out.interval / 1250) * qos->bcast.sync_factor; sync_interval = interval * 4; According to CORE SPECIFICATION Version 5.4 | Vol 4, Part E page 2451, the extended advertising interval should be at least 0x20 (32). Thus, interval should be at least 8. If qos->bcast.out.interval = 7500, it follows that the sync_factor should be at least 2.
