3>.Connect module to PC;
4>.Install CH340 drive software;
5>.Module starts initializing and LED indicator will Flashes once every second;
6>.LED indicator will Flashes once every 3 second after initialization successful;
7>.Start using.

Simple Operation:
1>.Call:
1.1>.Initiate a voice call:ATD189****3783;(Notice: semicolon; is needed!!! and ‘189****3783’ is a phone number).It will return OK if successful.
1.2>.Hang up a call: ATH.It will return OK if successful.
1.3>.Answer a call: ATA.It will return OK if successful.

2>.Send messages(TEXT MODE):
2.1>.After the module is automatically registered, user can start the operation.
2.2>.LED indicator will Flashes once every 3 second after initialization successful.It means module has linked 2G network.
2.3>.Communication instruction:
Send:AT+CMGF=1
Return:AT+CMGF=1
OK
Send:AT+CSCS='GSM'
Return:AT+CSCS='GSM'
OK
Send:AT+CMGS='10086'
Return:AT+CMGS='10086'
>
Send:The messages
(Note:The messages are just string with contain by '0~9' and 'A~Z')
Return:The messages
Send:1A
(Note:'1A' send as Hexadecimal)
Return:+CMSS:xxx
(E.g:+CMSS:237)

3>.GPRS Data transmission:
3.1>.AT+CGCLASS='B' //Set the mobile channel Class B, that is, the module supports packet switching and circuit switching mode, but does not support simultaneous operation.
Return:
AT+CGCLASS='B'
OK
3.2.>.AT+CGDCONT=1,"IP","CMNET" //Set PDP context flag 1 and use Internet Protocol (IP) access point as "CMNET"
Return:
AT+CGDCONT=1,"IP","CMNET"
OK
3.3>.AT+CGATT=1 //It is used to set up attachment and separation GPRS services.
Return:
AT+CGATT=1
OK
3.4>.AT+CIPCSGP=1,"CMNET" //Set GPRS connection, the access point is ”CMNET”.
Return:
AT+CIPCSGP=1,"CMNET"
OK
3.5>.AT+CLPORT="TCP","2000" //Set the TCP connection local port number to 2000.
Return:
AT+CLPORT="TCP","2000"
OK
3.6>.AT+CIPSTART="TCP","111.68.4.142",9090 //It is used to establish a TCP connection or register a UDP port number. The module will establish a TCP connection. For example, the connection destination address is 111.69.4.146 and the port is 9090. If the connection is successful, it will return: CONNECT OK (Note: the IP address needs to be the public IP address. )
Return:
AT+CIPSTART="TCP","111.68.4.142",9090
OK
CONNECT OK
3.7>.AT+CIPSEND //Module sends data to the server
Return:
AT+CIPSEND
>SIM800C test //Data content:SIM800C test.User can send other message.
Return:
SIM800C test
->
SEND OK  //Sent successfully
