CC2540(主机)与iOS(从机)蓝牙断开

Other Parts Discussed in Thread: CC2540

你好,我在使用CC2540与iOS设备进行蓝牙通信,CC2540作为主机,而iOS端则作为从机。现在我再编写iOS端作为从机内容的时候,和CC2540通信后,使用串口调试显示结果是:

BLE Central

Devices Found1

<- to select

connecting

connected

simple svc found

disconnected

reason:19

我想询问突然断开的具体原因是什么?封装后查看不了这块的代码。找了蛮久也不知道reason:19是什么意思。希望能够得到解答。谢谢。
