LWIP Network Interface network card initialization to STM32 as an example will be useful after 2G or 4G module in the form of PPP dial-up virtual network card, so first of all, this is the premiseLWIP has a structure that describes the physical interface of the Netif Struct, the great god of Chu has a detailed explanation of this: http://blog.csdn.net/zhzht198610
network communication Mode
There are two kinds of existing network communication methods:
1.TCP (Transmission Control Protocol) mode
TCP is a connection-oriented reliability transport protocol, TCP is like a telephone, use this way to communicate, need to establish a dedicated virtual connection, and then reliable data transmission, if the data sent failed, the client will automatically resend the data.
2.U
How many meters does the network cable transmit at most? Several common categories of network cable and network cable transmission
Maximum network cable data transmission distance
If you know more about the network, you know that the twisted pair wires have an insurmountabl
It is recommended that you set the network card NAT mode
Dynamic Network configuration:
1, be sure to open the local DHCP service
2. Select the NAT mode in the Virtual network editor to select the DHCP entry as shown below
3, Ifup eth0Static network configuration:

If you want external devices to access the local website, use the network cable to access the network connected by the route. if you want to ask a non-wireless network adapter, the local server will be connected by a wireless network card, an external device can access a local website through an automatically generated
1. The share in the computer's local connection is disabled by the administrator. Try some methods on the Internet, it is not OK. Finally think about modifying the registry. I found the shared option in the registry. Modify 0 to 1. The sharing of local connections is implemented.2. But even then, the temporary network shared by the local connection still does not have a valid IP address, so it cannot be connected. Try assigning their addresses manuall

For a common neural network, the previous information does not have an impact on the current understanding, for example, reading an article, we need to use the vocabulary learned before, and the ordinary neural network does not do this,

We recommend that you set the nic nat mode.
Dynamic Network Configuration: 1. You must enable the local DHCP service.
2. Select the DHCP option in NAT mode in the virtual network Editor,
Ask a question, the local server, with the wireless network card network, the external device can be automatically generated by IP access to the local site, and through the network cable routed through the network, IP becomes 192.168 ... , the external access is not, how to solve this?
