5.2.4.3
iChip enters Internet mode after being issued an Internet command such as to send or
receive an email message, open a socket, etc. iChip attempts to establish an Internet
connection and carry out the required activity through the communication platform link. While
in this mode, AT+i commands are supported to monitor and control the process , as well as
activate any of the supported protocols.
5.2.4.4
iChip‘s SerialNET mode extends a local asynchronous serial link to a TCP or UDP socket
across a LAN or Internet. Its main purpose is to allow simple devices, which normally interact
over a serial line, to interact in a similar fashion across a network, without requiring any
changes in the device itself. iChip contains a set of associated operational parameters , which
define the nature of the desired network connection. iChip supports both Server and Client
modes in SerialNET mode. AT+i commands are not required to operate SerialNET mode.
Thus, SerialNET mode may be used in existing systems with little or no need to modify the
application program.
5.2.4.5
iChip supports routing of Internet packets among its various communication platforms.
Available routing options are:
To provide seamless routing, iChip comes equipped with Network Address Translation (NAT)
capabilities and a DHCP server that supports up to 255 clients.
iChip performs routing as an operation mode in which, upon power -up or reset, only pre-
configured routing rules from one communication platform to another are applicable.
Alternatively, iChip can accept AT+i commands from the host while still maintaining
uninterrupted routing between two communication platforms.
Typical configurations for the routing mode are:
5.2.4.6
In this mode, iChip provides the host application with USB services, thus offloading USB
tasks and eliminating the need for the host to implement USB-related code. USB services can
be provided over the USB Device Port or USB Host Port. Typical services can be bridging
information from USB to another interface (Ethernet, for example), serving as a USB host or
client while using a simple interface such as UART to send and receive information from the
host application CPU.
