Part 1 – AT Commands for All Universal IP Devices

Chapter 6 – UDP AT Commands

#UDPDLEMODE – Set DLE Mode

Description:	The attached host has the choice whether or not to code the ETX character.
	Note: This command is for all devices except the SocketWireless Wi-Fi (MT810SWM-IP).
Notes:	If UDPDLEMODE is disabled, the user MUST use the RS232 DTR signal to perform a socket
	disconnect or disconnect the network connection
Details:	If UDPDLEMODE is enabled, these rules must be followed: The user must shield all transmitted
	ETX ([x03]) and DLE (x10) characters by preceding these characters with a DLE (x10).
	The UIP stack will shield all UDP received ETX ([x03]) and DLE (x10) characters by preceding
	these characters with a DLE (x10), the user must un-shield by removing the DLE (x10) shield
	character.
	An example payload to transmit from user to UIP stack:
	(x01 x02 x03 x04 x01 x10) must be sent to the UIP stack as: (x01 x02 x10 x03 x04 x01 x10
	x10). Notice the x10 before the [x03] and before the x10.
	An example received payload by the UIP over UDP:
	(x01 x02 x03 x04 x01 x10) is received by the UIP stack, the user will receive: (x01 x02 x10
	x03 x04 x01 x10 x10). Notice the x10 before the [x03] and before the x10.
	In summary: Encoding - 0x03 == 0x10 0x03
	Encoding - 0x10 == 0x10 0x10
	Decoding - 0x10 0x03 == 0x03
	Decoding - 0x10 0x10 == 0x10
	The REMOTE user does NOT have to perform any function pertaining to this mechanism.
	If the user receives an un-shielded 0x03, the socket is finished.
Syntax:	AT#UDPDLEMODE=<parameter1>
	AT#UDPDLEMODE? Read or display the current setting.
Values:	parameter 1
	0 No extra processing is needed on DLE (x10) and ETX ([x03]) characters
	1 The ETX character is used as a socket disconnect or indicates a socket disconnect
Responses:	\r\n#UDPDLEMODE: VALUE\r\n
	\r\nOK\r\n
	\r\nERROR\r\n

Command Example(s):

send: AT#UDPDLEMODE=0\r reply: \r\nOK\r\n

send: AT#UDPDLEMODE?\r reply: \r\n#UDPDLEMODE: 0\r\n reply: \r\nOK\r\n

#LUDPSTART – 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.

Syntax: AT#LUDPSTART

Values: UDPPORT

UDPSESRV

UDPTXDELAY

No default
