iOS BLE errorCode = 6 蓝牙几分钟断开一次

手机连接上了蓝牙,能够正常的通信,但是每隔几分钟就断开一次,报的错误是The connection has timed out unexpectedly. errorCode = 6;

蓝牙协议文档上对改错误代码的说明如下：
2.6 PIN OR KEY MISSING (0X06)
The PIN or Key Missing error code is used when pairing failed because of a
missing PIN, or authentication failed because of a missing Key.
意思是缺少密钥验证失败。
