STA:

AT+SOCKET=0,4001,101.145.45.1

After the configuration is complete, restart the device, wait for the connection to be completed, and then send data.

Special attention is needed: Before starting the STA, the IP address of the AP connected to it must be passed in.

Otherwise, a normal network connection cannot be established.

If the AP starts the protocol transmission mode at this time, it can support the connection of 4 STAs, and the

configuration of the remaining STAs is the same.

For STA-STA communication, two devices need to be connected to the same router. Here, the SSID of the target AP

is E103-W06 for demonstration.

STA1 configuration process

Mode: AT+MODE=2,1,1

Target: AT+STACON=E103-W06,2,12345678

Configure the local port: AT+SVRPORTIP=4001

Get IP address: AT+SVRPORTIP? Get back: AT+SVRPORTIP=4001,192.168.0.189

STA2 configuration process

Mode: AT+MODE=2,1,2

Target: AT+STACON=E103-W06,2,12345678

Set the remote IP and port, here the IP and port obtained by STA1 are passed in:

AT+SOCKET=0,4001, 192.168.0.189

Restart the device and wait for the connection to complete before communicating.

5.1.5 UDP communication between devices

UDP is a communication that does not establish a connection, and the core is the IP address and port. In this way,

one serves as AP and the other serves as STA.

(1) Configure AP equipment:

Setting mode: AT+MODE=1,1,3

Set SSID: AT+SSID=0,E103-W06,2,12345678

Set the local port: AT+SVRPORTIP=4001

Get the local IP of the local port: AT+SVRPORTIP?. Get back: AT+SVRPORTIP=4001,10.145.45.1

Set remote port Set remote IP: AT+SOCKET=0,4002,10.145.45.2
