When the ETA6103 works, the software is used as a serial port, and the AT command is sent to establish an internet connection. Configuration information, network data transmission is transmitted through a serial port. In order to facilitate user programming, Britain has encapsulated a CuartWifi class, providing a public function for configuring wireless networks and establishing TCP / UDP transfer, and users do not have to care for specific AT instructions.
Instructions for use
Reference routines UART_WIFI, add serial.h, serial.cpp, eta6103.h, etc., ETA6103.cpp.
Add a reference #include "eta6103.h"
You can create classes and use cuartwifi mywifi;
WiFi connection management
Reference routine APCONNECT, this routine simplicity how to manage AP connection
Call Open, AutoCFG method initialization module
Call the getaplist method query near the AP
Call Connectap method connection AP
Call the setFAP to set the AP after the default connection after the power is called (cannot be set when the AP cannot be connected)
Call the disconnectap method to disconnect the AP connection
Call the GetCurip query AP assigned to the IP address
UDP communication
Reference routine UDP.
Call Open, AutoCFG method initialization module
Cuartwifi m_eta6103;
m_eta6103.open ();
M_eta6103.autocfg ();
Call ConnectUDP to open the UDP connection, and create a thread to wait for the message to receive
IP = "192.168.201.248";
RPORT = 6000;
LPORT = 5000;
Bret = m_eta6103.connectudp (0, IP, RPORT, LPORT);
m_hrecvthread = CreateThread (0, 0, Recvtread, this, 0, null);
Send data to the distal end
Charstr [32] = "Test UDP";
Len = Strlen (STR);
Bret = m_eta6103.sendmsg (0, Str, LEN);
Receive thread
DWord Cudpdlg :: Recvtread (LPVOID LPARAM)
{
CUDPDLG * PDLG = (cudpdlg *) LPARAM;
DWORD DWLEN;
CharRecvbuf [1024];
While (! pdlg->m_bthreadstop)
{
PDLG->m_eta6103.waitmsg (); // Waiting for the message
IF (dwret == Wait_Object_0)
{
PDLG->m_eta6103.readmsg (0, Recvbuf, 1023, & DWLEN);
// read data
While (dwlen>0)
{
// Processing code
PDLG->m_eta6103.readmsg (0, Recvbuf, 1024, & DWLEN);
// Recycled until reading buffer
}
}
} // While (! pdlg->m_bthreadstop)
Return0;
}
TCP client communication
Reference routine TCPCLIENT.
Call Open, AutoCFG method initialization module
Cuartwifi m_eta6103;
m_eta6103.open ();
M_eta6103.autocfg ();
Call ConnectUDP to open the UDP connection, and create a thread to wait for the message to receive
IP = "192.168.201.248";
Port = 6000;
Bret = m_eta6103. ConnectTCPServer (0, IP, Port);
m_hrecvthread = CreateThread (0, 0, Recvtread, this, 0, null);
Send data to the distal end
Charstr [32] = "test tcpclient";
Len = Strlen (STR);
Bret = m_eta6103.sendmsg (0, Str, LEN);
Receive thread
DWord Cudpdlg :: Recvtread (LPVOID LPARAM)
{
CUDPDLG * PDLG = (cudpdlg *) LPARAM;
DWORD DWLEN;
CharRecvbuf [1024];
While (! pdlg->m_bthreadstop)
{
PDLG->m_eta6103.waitmsg (); // Waiting for the message
IF (dwret == Wait_Object_0)
{
PDLG->m_eta6103.readmsg (0, Recvbuf, 1023, & DWLEN);
// read data
While (dwlen>0)
{
// Processing code
PDLG->m_eta6103.readmsg (0, Recvbuf, 1024, & DWLEN);
// Recycled until reading buffer
}
}
} // While (! pdlg->m_bthreadstop)
Return0;
}
It can be seen that the TCP client uses and UDP almost the same, but the function called when connected is different.
TCP server communication
Reference routine TCPCLIENT.
Call Open, AutoCFG method initialization module
Cuartwifi m_eta6103;
m_eta6103.open ();
M_eta6103.autocfg ();
Call CreateTCPServer Open the server connection and create a thread to listen to client connection and data reception.
Port = 6000;
Bret = m_eta6103. CreateTCPServer (port);
m_hrecvthread = CreateThread (0, 0, Recvtread, this, 0, null);
Send data to the corresponding client
Charstr [32] = "Test TCPServer";
INTID = 1; // Send information to the client of the link number 1
Len = Strlen (STR);
Bret = m_eta6103.sendmsg (ID, str, len);
Receive thread
In the routine, receive client connections and messages, encapsulate into the same event, and then determine the type of event by marking bit, the customer can modify the package code as needed, change to each event, or modified to multiple Threads to process connection events, and messages receive events.
DWORD CTCPSERVERDLG :: Recvtread (LPVOID LPARAM)
{
CTCPSERVERDLG * PDLG = (CTCPSERVERDLG *) LPARAM;
DWORD DWLEN;
CharRecvbuf [1024];
DWORD DWRET;
Intlen;
Inti;
INTN;
While (! pdlg->m_bthreadstop)
{
DWRET = PDLG->m_eta6103.waitmsg ();
IF (dwret == Wait_Object_0)
{
For (i = 0; I<5; i ++)
{
IF (pdlg->m_eta6103.m_link [i] .Eventflag & evt_stat) // state change
{
IF (pdlg->m_eta6103.m_link [i] .stat == 0) // close
{
// User Disconnect Code Processing
}
Else // connect
{
// User connection code processing
}
}
IF (pdlg->m_eta6103.m_link [i] .Eventflag & evt_recv) // data reception
{
PDLG->m_eta6103.readmsg (i, recvbuf, 1020, & dwlen);
While (dwlen>0)
{
// Data Receive Code Processing
PDLG->m_eta6103.readmsg (0, Recvbuf, 1024, & DWLEN);
}
}
IF (pdlg->m_eta6103.m_link [i] .Eventflag & evt_err) // Error event
{
// Error event code processing
}
PDLG->m_eta6103.m_link [i] .Eventflag = 0;
}
}
} // While (! pdlg->m_bthreadstop)
Return0;
}
Speed test routine
Routing TestSpeed is used to test file reception speed. The baud rate (maximum 460800, recommended by default 115200) via setCuruart), the user can select the configuration that best suits you.
Note that during high-speed transmission, if the receiving buffer is not ever, the data packet is lost. Recommended reference routines, add processing code in the corresponding location. Read more
