After the connection interval is set, it will only take effect when the device is initialized, which is
equivalent to restarting. The minimum connection interval between module and the mobile phone
APP is 20 ms (the minimum connection interval for Apple is 30 ms), and the connection interval
between modules can be less than 20 ms (minimum 8 ms). After the connection interval takes effect,
the connection interval will be coordinated according to different mobile phones, up to the "set
connection interval*3".
