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.
Set Value: AT#UDPPORT=<Port Number Value>
View Value: AT#UDPPORT?
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.
1234
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.
Set Value: AT#UDPSERV=<Value>
View Value: AT#UDPSERV?
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.
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.
Set Value: AT#UDPTXDELAY=<Value>
View Value: AT#UDPTXDELAY?
Integer, multiple of 20 and between 0 and 32760 inclusive.
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.
