发送队列 定义

Other Parts Discussed in Thread: Z-STACK

各位大神

z-stack里面有个发送队列,就是最多能存3个设备,最多能存9条数据的那个队列的名称叫什么?

还有,那个队列我能操作吗?

拜托拜托!

    • OSAL的消息队列
    每一个消息都包含一个消息头osal_msg_hdr_t和用户自定义的消息,osal_msg_hdr_t结构体定义如下:
    1. typedef struct
    2. {
    3. void *next;
    4. uint16 len;
    5. uint8 dest_id;
    6. } osal_msg_hdr_t;
     

       在事件处理函数SampleApp_ProcessEvent()中,从消息队列中接收到一个消息,后才调用SampleApp_MessageMSGCB,接收到的消息中如何就包含了用户接收的数据消息呢?
    是这样子的:每个消息都有一个用户自定义的消息部分,协调器收到数据后,将数据打包,存放在用户自定义消息部分,然后将其插入到消息队列,用户就可以从消息队列接收该消息
    接收到数据后的消息格式如下图所示。
    • AF层的数据包结构体:afIncomingMSGPacket_t
    1. typedef struct
    2. {
    3. osal_event_hdr_t hdr; /* OSAL Message header */
    4. uint16 groupId; /* Message's group ID - 0 if not set */
    5. uint16 clusterId; /* Message's cluster ID */
    6. afAddrType_t srcAddr; /* Source Address, if endpoint is STUBAPS_INTER_PAN_EP,
    7. it's an InterPAN message */
    8. uint16 macDestAddr; /* MAC header destination short address */
    9. uint8 endPoint; /* destination endpoint */
    10. uint8 wasBroadcast; /* TRUE if network destination was a broadcast address */
    11. uint8 LinkQuality; /* The link quality of the received data frame */
    12. uint8 correlation; /* The raw correlation value of the received data frame */
    13. int8 rssi; /* The received RF power in units dBm */
    14. uint8 SecurityUse; /* deprecated */
    15. uint32 timestamp; /* receipt timestamp from MAC */
    16. afMSGCommandFormat_t cmd; /* Application Data */
    17. } afIncomingMSGPacket_t;
    • af地址类型
    1. typedef struct
    2. {
    3. union
    4. {
    5. uint16 shortAddr; //16位网络地址
    6. ZLongAddr_t extAddr; //设备IEEE64位物理地址
    7. } addr;
    8. afAddrMode_t addrMode;
    9. byte endPoint;
    10. uint16 panId;
    11. } afAddrType_t;
    • 数据传输模式
    1. typedef enum
    2. {
    3. afAddrNotPresent = AddrNotPresent,
    4. afAddr16Bit = Addr16Bit, //点播
    5. afAddr64Bit = Addr64Bit,
    6. afAddrGroup = AddrGroup, //组播
    7. afAddrBroadcast = AddrBroadcast //广播
    8. } afAddrMode_t;
    1. afStatus_t AF_DataRequest( afAddrType_t *dstAddr, endPointDesc_t *srcEP,
    2. uint16 cID, uint16 len, uint8 *buf, uint8 *transID,
    3. uint8 options, uint8 radius )
      
  • 不好意思,不是这个队列

  • 这个队列是实现什么功能的?

  • 我找到了,参考一下下面的定义:

       》NWK_INDIRECT_MSG_MAX_PER

       》NWK_INDIRECT_MSG_MAX_ALL
