simple_observer扫描到的设备

请看如下两个事件：
GAP_DEVICE_INFO_EVENT 每发现一个设备就会产生一次 ，对应的是pEvent->deviceInfo

GAP_DEVICE_DISCOVERY_EVENT 是发现过程完成了产生一次，对应的是pEvent->discCmpl.numDevs

可在相应的结构体中查找信息，比如：

typedef struct
{
osal_event_hdr_t hdr; //!< GAP_MSG_EVENT and status
uint8 opcode; //!< GAP_DEVICE_INFO_EVENT
uint8 eventType; //!< Advertisement Type: @ref GAP_ADVERTISEMENT_REPORT_TYPE_DEFINES
uint8 addrType; //!< address type: @ref ADDRTYPE_DEFINES
uint8 addr[B_ADDR_LEN]; //!< Address of the advertisement or SCAN_RSP
int8 rssi; //!< Advertisement or SCAN_RSP RSSI
uint8 dataLen; //!< Length (in bytes) of the data field (evtData)
uint8 *pEvtData; //!< Data field of advertisement or SCAN_RSP
} gapDeviceInfoEvent_t;

typedef struct
{
osal_event_hdr_t hdr; //!< GAP_MSG_EVENT and status
uint8 opcode; //!< GAP_DEVICE_DISCOVERY_EVENT
uint8 numDevs; //!< Number of devices found during scan
gapDevRec_t *pDevList; //!< array of device records
} gapDevDiscEvent_t;
