本文详细介绍了iOS设备对于蓝牙连接参数的具体要求，包括连接监督超时时间、最小和最大间隔等关键参数的规定，确保配件与iOS设备之间的稳定连接。
iOS对蓝牙连接参数有明确要求。之前项目中的连接参数不符合要求，通信过程中会自动断开。
最新参数要求请查看 :

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.
