GAP_MSG_EVENT and status. gapDeviceInitDoneEvent_t initDone; //! GAP initialization done. gapDeviceInfoEvent_t deviceInfo; //! Discovery device information event structure. gapDevDiscEvent_t discCmpl; //! Discovery complete event structure. gapEstLinkReqEvent_t linkCmpl; //! Link complete event structure. gapLinkUpdateEvent_t linkUpdate; //! Link update event structure. gapTerminateLinkEvent_t linkTerminate; //! Link terminated event structure.} gapCentralRoleEvent_t;联合体，只有deviceInfo里面的数据是正确的typedef struct{ osal_event_hdr_t hdr; //! GAP_MSG_EVENT and status uint8 opcode; //! GAP_DEVICE_INIT_DONE_EVENT uint8 devAddr[B_ADDR_LEN]; //! Devices BD_ADDR uint16 dataPktLen; //! HC_LE_Data_Packet_Length uint8 numDataPkts; //! HC_Total_Num_LE_Data_Packets} gapDeviceInitDoneEvent_t;能获得如设备地址等信息设备初始化完成通过串口发送1触发设备发现进行设备扫描GAP_DEVICE_INFO_EVENT 0x0D //! Sent during the Device Discovery Proc
