Esp8266 becomes client and server

1、ESP8266 Become a client for data transparent transmission

• Create hotspots with your phone ,ID：Eddie,Pwd：13194472899,PC Connect to this hotspot

• testing Wifi modular AT Status and set to STA Pattern ( Pattern 1)
  

• Connect to hotspot
  

• View computer properties PC Of IP Address and through the network debugging assistant PC Configure as server , The port is set to 8081（ at will ）
  
  

• Because you are connected to the same server ,Wifi modular AT Configuration lookup IP And port , The two devices can communicate with each other
  

• Enter the passthrough and start the passthrough
  

• Send messages to each other
  

• +++ Quit touzhuan

2、ESP8266 Become the communication between the server and the network debugging assistant

• testing Wifi modular AT Status and set to AP Hot mode ( Pattern 2)
  
• Hotspot setting port number
  
• see Wifi IP Address
  
• The network debugging assistant is set as the client
  

frequently-used AT Instructions

AT+CWMODE=1									//STA Pattern , Connect to others' hot spots 
AT+CWMODE=2									//AP Pattern , Become a hot spot 
AT+CWMODE=3									//STA and AP Dual mode 

AT+CIFSR									// see Wifi The equipment IP Information 

AT+CWJAP="ID","PWD"							// Join in AP hotspot , account number ID, password PWD

AT+CIPSTART="TCP","IP Address","PORT"		// adopt TCP To connect to ip Address and Port Port server 
AT+CIPMODE=0								// Transparence mode off 
AT+CIPMODE=1								// Turn on transmission mode 
AT+CIPSEND=1								// Start penetrating 

AT+CIPMUX=1									// Set to multi connection mode 
AT+CIPSERVER=mode,port						// for example ：AT+CIPSERVER=1,8082		1： Turn on server mode ,port： Set the port
