35.6 Connection Parameters The connection parameter request may be rejected if it does not comply with all of these rules:

- Bluetooth device latency 30

- 2 seconds connSupervisionTimeout 6 seconds

- Interval Min modulo 15 ms == 0

- Interval Min ≥15 ms

- One of the following:

- Interval Min + 15 ms Interval Max

- Interval Min == Interval Max == 15 ms

- Interval Max * (Bluetooth device latency + 1) 2 seconds

- Interval Max * (Bluetooth device latency + 1) * 3 < connSupervisionTimeout Note that if an accessory requests Interval Min == Interval Max == 15 ms, some devices will scale the interval to 30 ms to balance power and performance constraints.
