手机莫名其妙就会断开蓝牙

在手机连接蓝牙的情况下，手机会出现不确定时间的断开蓝牙，手机APP有重连程序，所以马上又可以连接上，有点莫名其妙（是在没有板载天线的情况下测试的）

/// Minimum Connection Event Duration measured in ble double slots (1.25ms)
/// use the macro MS_TO_DOUBLESLOTS to convert from milliseconds (ms) to double slots
.ce_len_min = MS_TO_DOUBLESLOTS(0),

/// Maximum Connection Event Duration measured in ble double slots (1.25ms)
/// use the macro MS_TO_DOUBLESLOTS to convert from milliseconds (ms) to double slots
.ce_len_max = MS_TO_DOUBLESLOTS(0),

这两个参数有什么作用吗，麻烦解释一下 = =！
