1. Introduction
- Hardware: 4 CC2530 modules, 2 DS18B20 temperature sensors, 1 DHT11 sensor, and 1 pump (none).
- Software: Develop PC (.NET Framework 4.8), ZStack-2.5.1a protocol stack based on C#
- Star network is composed of coordinators and nodes, and can access up to six terminal nodes by on-demand communication (P2P), combined with the upper limit.
- Hardware Effect Diagram
2. Upper computer data collection
(1) Data collection
Open the serial port to show the situation and fluctuation.
(2) Topology
Displays the data of the node and its short address.
(3) New nodes join the network
(4) Node events
Node 4 humidity is higher than 70%, indicating that the topology graph hides the node while the pump stops working.
3. Realization Analysis
(1) Profile
- In f8wConfig. In CFG
Set Channel: -DDEFAULT_CHANLIST=
(Channel 11 seems to be susceptible to WIFI signals)
Set PAN_ID:-DZDAPP_CONFIG_PAN_ID= - In SamplleApp. H
Data send interval 3 s
#define SAMPLEAPP_SEND_PERIODIC_MSG_TIMEOUT 3000
(2) Send
- In SamplleApp. C
//Wireless Send to Coordinator
if ( AF_DataRequest( &SampleApp_P2P_DstAddr, &SampleApp_epDesc,
SAMPLEAPP_P2P_CLUSTERID,
len, // Data Length
str, // Data Content
&SampleApp_MsgID,
AF_DISCV_ROUTE,
AF_DEFAULT_RADIUS ) == afStatus_SUCCESS )
{
}
}
(3) Short address and data acquisition
Short address pkt->srcAddr. Addr. ShortAddr is randomly assigned to the network.
The MAC address pkt->macDestAddr is more suitable as the primary key for data storage.
Data uint8 temperature=pkt->cmd. Data [0]; Uint8 humidity=pkt->cmd. Data [1];
- In AF.h
typedef struct
{
union
{
uint16 shortAddr; // (short address)
ZLongAddr_t extAddr;
} addr;
afAddrMode_t addrMode;
uint8 endPoint;
uint16 panId; // used for the INTER_PAN feature
} afAddrType_t;
typedef struct
{
osal_event_hdr_t hdr; /* OSAL Message header */
uint16 groupId; /* Message's group ID - 0 if not set */
uint16 clusterId; /* Message's cluster ID (Cluster ID) */
afAddrType_t srcAddr; /* Source Address, if endpoint is STUBAPS_INTER_PAN_EP,
it's an InterPAN message */
uint16 macDestAddr; /* MAC header destination short address (MAC Address) */
uint8 endPoint; /* destination endpoint */
uint8 wasBroadcast; /* TRUE if network destination was a broadcast address */
uint8 LinkQuality; /* The link quality of the received data frame (Network Connection Quality) */
uint8 correlation; /* The raw correlation value of the received data frame */
int8 rssi; /* The received RF power in units dBm (Signal energy) */
uint8 SecurityUse; /* deprecated */
uint32 timestamp; /* receipt timestamp from MAC */
uint8 nwkSeqNum; /* network header frame sequence number */
afMSGCommandFormat_t cmd; /* Application Data */
} afIncomingMSGPacket_t;
- In SamplleApp. In H
void SampleApp_ProcessMSGCmd( afIncomingMSGPacket_t *pkt )
{
uint8 buff[50]={0};
switch ( pkt->clusterId )
{
// Temperature and humidity data uploaded by receiving terminal
case SAMPLEAPP_P2P_CLUSTERID:
{
// Remove temperature and humidity data
uint8 temperature = pkt->cmd.Data[0];
uint8 humidity= pkt->cmd.Data[0];
// Take out the short address
uint16 shortAddress = pkt->srcAddr.addr.shortAddr;
// Processing and data packaging upload serial interface
}
break;
// Receiving temperature
case SAMPLEAPP_DS18B20_CLUSTER:
{
// Left....
}
break;
default:
break;
(4) Data package analysis
Serial data packaging format:
Length: 14;
Check bits: C4;
Function code: 02;
Data: 3B 31 3B 54 3A 32 37 2E 30 20 43 3B 34 34 31 3B
End: 0D 0A.
supplement
- The 3B of the data section acts as the data content separator (;): (Function Code)+(;)+ (Collect data)+(;)+ (short address)+(;).
- And end with a line break\rn
(5) Upper computer
// Whether to open serial port
bool isOpenSP;
// Number of records

// Recording the detection results of each node for topology
private string[] pointsTopology = {"", "", "", "", "", ""};
// Mapping

IV. IAR
- There seems to be a corresponding link between the IAR software and the protocol stack, and the Z-stack 2.5.1 protocol stack compiled under the higher version of IAR had problems Reference resources
