1+MIPOPEN,Open a Socket
(UDP/TCP/SSL)
This command causes the G5xx module to initialize a new socket that waits for a connection from a remote machine or opens a common connection with a remote side(according to received parameters). Each socket allocates an accumulating buffer whose size is1372bytes for TCP connection and1024 bytes for UDP connection.If Parameter“Protocol”=2,it opens a secure connection with the remote server which supports Secure Sockets Layer(SSL).
Note:MIPxxx is a complete set of GPRS commands.This set should not be used with other GPRS commands,such as CGATT,CGACT,and so on.The+MIPOPEN command returns a+MIPSTAT unsolicited event if it fails,for example,if it was rejected by the remote side.This command will return in 60sec when DNS is error.
Command Syntax Response/Action Remarks
Set AT+MIPOPEN= et_ID>, e_Port>, or: +MIPOPEN: P>, or: +MIPSTAT: or: ERROR: The Set command returns parameters only for sockets opened in Listen mode. Read AT+MIPOPEN?+MIPOPEN:[ for each socket that can be opened OK or:The Read command returns the numbers of the sockets that can be opened. +MIPOPEN:0 OK if there are no free sockets. Test AT+MIPOPEN=?+MIPOPEN:(list of supported supported supported<"Destination_IP">s), (list of supported OK Example: AT+MIPOPEN? +MIPOPEN:1,2,3,4//All sockets closed OK AT+MIPOPEN? +MIPOPEN:1,3,4//Socket2opened OK The following table shows the+MIPOPEN parameters. Socket_ID A unique number that identifies a connection. Valid socket numbers-1,2,3and4 Source_Port Port of source site. Port range:1-65535(decimal digits) Remote_IP IP:IP of the remote site in the format"https://www.sodocs.net/doc/b18261677.html,C.DDD".The range of each octet is0-255.Value can be written in1,2,or3digits.Host name:of remote site.The host-name convention should meet the rules as describe in RFC-1035section:2.3 Conventions.Syntax is not validated,except the maximum length(255characters). Remote_Port Port of remote site. Port range:1-65535(decimal digits)for outgoing connection. Port0for incoming connection. Protocol Type of protocol stack. 0TCP 1UDP 2SSL State0Inactive 1Active Note:Port numbers below1024are not recommended,as they are used by system processes.
