Part 1 – AT Commands for All Universal IP Devices

Chapter 5 – TCP AT Commands

#TCPINACTIVITYTIMER – TCP Client Inactivity Timeout Value

	Description:	This parameter determines the inactivity time in seconds as to when a socket connection will
		automatically disconnect.
		Note: Data transmission from either the remote or local side will reset the internal timer
		to the #TCPINACTIVITYTIMER value
		Note: This command is for all devices except the SocketWireless Wi-Fi (MT810SWM-IP)
	Syntax:	AT#TCPINACTIVITYTIMER=<parameter1>, <parameter2>
	Values:	parameter 1
		1 TCP profile 1
		2 TCP profile 2
		parameter 2
		0-65535 – the time in seconds of inactivity before a socket will automatically disconnect. A
	Responses:	setting of 0 will disable the function.
	Responses:	\r\n#TCPINACTIVITYTIMER: VALUE1,VALUE2\r\n
		\r\n#TCPINACTIVITYTIMER: VALUE1,VALUE2\r\n
		\r\nOK\r\n
		\r\nERROR\r\n
	Examples:	send: AT#TCPINACTIVITYTIMER=1,100\r
		send: AT#TCPINACTIVITYTIMER=1,100\r
		reply: \r\nOK\r\n
		send: AT#TCPINACTIVITYTIMER=1\r
		reply: \r\n#TCPINACTIVITYTIMER: 1,100\r\n
		reply: \r\nOK\r\n
		send: AT#TCPINACTIVITYTIMER=2,300\r
		reply: \r\nOK\r\n
		send: AT#TCPINACTIVITYTIMER=2\r
		reply: \r\n#TCPINACTIVITYTIMER: 2,300\r\n
		reply: \r\nOK\r\n

#TCPNETWORKTIMER – TCP Client Network Transmit Safety Timeout Value

Description:	This parameter determines the inactivity time in seconds of the TCP TX buffer.
	Note: This command is for all devices except the SocketWireless Wi-Fi (MT810SWM-IP)
Syntax:	AT#TCPNETWORKTIMER=<parameter1>, <parameter2>
Values:	parameter 1
	1 TCP profile 1
	2 TCP profile 2
	parameter 2
	0-65535 – the time in seconds the client will wait for the TCP available TX buffer to be greater
	than 0. A setting of 0 will disable the function.
Responses:	\r\n#TCPNETWORKTIMER: VALUE1,VALUE2\r\n
	\r\nOK\r\n
	\r\nERROR\r\n
Examples:	send: AT#TCPNETWORKTIMER=1,100\r
	send: AT#TCPNETWORKTIMER=1,100\r
	reply: \r\nOK\r\n
	send: AT#TCPNETWORKTIMER=1\r
	reply: \r\n#TCPNETWORKTIMER: 1,100\r\n
	reply: \r\nOK\r\n
	send: AT#TCPNETWORKTIMER=2,300\r
	reply: \r\nOK\r\n
	send: AT#TCPNETWORKTIMER=2\r
	reply: \r\n#TCPNETWORKTIMER: 2,300\r\n
	reply: \r\nOK\r\n
