34.12.4 +iRRRL — IP Registration Return Link
Syntax: AT+iRRRL=IP[:Port] Permanently sets the IP registration Return Link
IP and Web Port.
Parameters: IP = IP address to use for registration after going
online.
Port = Port number to assign to iChip‘s Web
server.
See description of RRRL when registering IP.
Command Options:
IP = 0.0.0.0 Empty: No Return Link defined.
IP = <IP_add> IP_addr will be used when registering after
establishing an Internet session, rather than the
iChip‘s actual local IP address. This is useful
when the iChip receives an internal IP address
behind a NAT. Assigning the NAT‘s IP address to
IP_addr will allow reaching the iChip from the
Internet. In SerialNET, the
LPRT parameter may
be pre-configured in the NAT to connect to the
iChip device. See SerialNET Server Devices.
Port = Web_port Optional port to map iChip‘s Web server in order
to allow surfing iChip across a NAT in association
with IP_addr.
Default: Empty. No return link IP and Port defined.
Result code:
I/OK If IP is a legal IP address and Port is a legal IP
port number.
I/ERROR Otherwise.
AT+iRRRL? Report the current return link IP and port.
The reply is followed by I/OK.
AT+iRRRL=? Returns the message ―Name/IP[:Port]‖.
The reply is followed by I/OK.
