Instructions
Connect the module to the 2.4GHz GSM antenna and insert the SIM card (Note: support Micro/Nano card, support China Mobile or China Unicom mobile phone 2G/3G/4G card, but does not support 3G/4G network, does not support telecom card), plug in On the USB port of the computer, the serial port driver of CH340 needs to be installed for the first time.
After the module is started, the indicator light flashes once in 1 second. After a period of initialization, the indicator light changes to 3 seconds, and the module starts to work normally. Then you can control the SIM800C module with the AT command.
1, call
Initiate a voice call: ATD189****3783; must be added a semicolon, please note! ! !
Hang up the call: ATH answering the call: ATA
2, send the English text message (TEXT mode) plug in the SIM card, start the module, the module can be operated after the module registration is successful (the indicator 3S lights up once, indicating that the module has been registered to the 2G network).
Send: AT+CMGF=1 return: AT+CMGF=1
OK to send: AT+CSCS="GSM" return: AT+CSCS="GSM"
OK to send: AT+CMGS="10086" return: AT+CMGS="10086"
>
Send: XXXXXX (0-9, A-Z) [XXXXX refers to Arabic numerals 0-9, English 26 letters A-Z]
Note: XXXXXX is the content of the text message to be sent.
Returns: XXXXXX(0-9,A-Z)[XXXXX means Arabic numerals 0-9, English 26 letters A-Z]
Send: 1A (hexadecimal transmission) Note: There will be a +CMGS command return after successful transmission.
For example, use the mobile phone to send SMS "LCTECH" to "10086". Proceed as follows:
3, GPRS data transmission
AT+CGCLASS="B"//Set the mobile station class to B, that is, the module supports packet switching and circuit switching mode, but not both.
return:
AT+CGCLASS="B"
OK AT+CGDCONT=1, IP", "CMNET"//Set PDP context flag 1, using Internet Protocol (IP) access point as "CMNET"
return:
AT+CGDCONT=1, "IP", "CMNET"
OK AT+CGATT=1// is used to set the attachment and separation of GPRS services back:
AT+CGATT=1
OK AT+CIPCSGP=1, "CMNET"/ is set to GPRS connection, the access point is
"CMNET"
return:
AT+CIPCSGP=1, "CMNET"
OK AT+CLPORT="TCP", "2000"//Set the TCP connection local port number to 2000 to return:
AT+CLPORT="TCP", "2000"
OK AT+CIPSTART="TCP", "111.68.4.142", 9090// 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. Successful connection will return: CONNECT OK
(Note: The IP address needs to be the public IP address).
return:
AT+CIPSTART="TCP","111.69.4.146",9090
OK CONNECT OK
AT+CIPSEND// module sends data to the server
return:
AT+CIPSEND
>SIM800C test//Data content: SIM800C test
return:
