Why dns?
Actually, the remote IP is always dynamic (not fixed) when to transmit data through internet
in the real application, how to get and refresh the remote ip when it has been chanced?
Nechip can provide such solution for such application. NeChip can support dns to query for
IP with a domain name point to your remote machine.
Especially, nechip can auto-detect and diagnose the connection status in time, check and
refresh the remote IP for new connection if the remote IP is changed.
This function will solve the problem in the real internet application with dynamic remote IP
Why SMTP?
As we know that smtp is the basic protocol to transmit email. How is this protocol used in the
real M2M application?
NeChip series provide such protocol to trigger emails for alerts. When the
terminal/customer’s devices detect some warning/important evens, but the data connection
is blocked or remote host is not available. How to report such warnings to the host or device
manager. Emails will become the available way to notify the manager in time.
Why PPP?
Ppp stacks include several protocols, such as LCP, PAP, CHAP, IPCP.
ISDN:
In the traditional industrial applications, remote devices are connected through telephone
lines.
Nechip can support such application by attaching an external modem to any uart of nechip,
Then nechip will dial up automatically by internal ppp machine
GPRS:
GSM is the worldwide wireless communication network which can provide internet service
for GSM terminals, so gsm cellphones can upload and download data from internet. In M2M
applications, the distributed devices also can be connected and communicate with each
other through gsm networking. It can reduce the cost on building wired channel.
Nechip can support driver the external gprs module directly through serial port
(Refer to application for more details)
Why PPPoE?
Nechip can support connect to ADSL modem directly and dial up automatically without any
router. Simple the method to internet and reduce the cost on an additional router As internet
server.
