#TCPAUTOCONNECT – Auto Connect to TCP Server
Description:
Commands to activate auto connect to TCP server can be used after power on. This will
allow legacy devices to be on the network without having to do any programming.
Syntax:
Set Value: AT#TCPAUTOCONNECT=<value>
View Value: AT#TCPAUTOCONNECT?
Values:
0: Manually connect by giving AT commands (Disabled)
1: automatically connect to pre-configured IP address, port (Enabled)
Default
Value: 0: Disabled
#UDPPORT – UDP Port Number
Description:
If the UDP session is initiated in listen mode, use the local UDP port number. If the UDP
session is initiated in active mode, use the remote UDP port number.
Syntax:
Set Value: AT#UDPPORT=<Value>
View Value: AT#UDPPORT?
Values:
From 1 to 5 numeric digits (0 to 9).
Notes:
Numbers above 65,535 are illegal as the port identification fields are 16-bits long
in the IP header. Port number 0 is illegal.
Default
Value: 1234
#UDPSERV – UDP Server Address
Description:
If the UDP session is initiated in listen mode, use the IP address filter. This means that
the remote must have a defined UDPSERV IP address. If the UDP session is initiated in
active mode, use the remote IP address.
Syntax:
Set Value: AT#UDPSERV=<Value>
View Value: AT#UDPSERV?
Values:
32-bit number is dotted-decimal notation (i.e., xxx.xxx.xxx.xxx) or Alphanumeric ASCII
text string up to 120 characters if DNS is integrated.
Default
Value: None
#UDPTXDELAY – Delay before Sending UDP Datagram
Description:
This parameter determines the delay before sending an UDP datagram that has not been
entirely filled with user data. The delay is expressed in milliseconds. The 0 value initiates
the sending an UDP datagram as soon as possible after the reception of a single
character value from the host.
Syntax:
Set Value: AT#UDPTXDELAY=<Value>
View Value: AT#UDPTXDELAY?
Values:
Integer, multiple of 20 and between 0 and 32760 inclusive.
Default
Value: 0
#UDPSTART – Initiate the UDP Session in Listen Mode
Description:
Once an IP link is established, and if no other TCP/IP stack resource is active, this
command sent by the attached host directs the TCP/IP stack to initiate the UDP session
in listen mode on the specified UDP local port UDPPORT (depending on the UDPSERV
parameter content).
Syntax:
Set Value: AT#UDPSTART
Values:
UDPPORT
UDPTXDELAY
Default
Value: None
