How can I do this without Ethernet for Iot!
Based on enc28j60, our team independently implemented the Ethernet protocol stack tinyip. Currently, ARP, ICMP, TCP, UDP, and DHCP are supported, and only one DNS is complete.
Tinyip has a built-in data buffer. After receiving the data, enc28j60 puts it into the buffer zone, tinyip then splits and restructured the data based on the Ethernet/arp/IP/ICMP/TCP/UDP/DHCP header structure to execute the business logic.
Tinyip is completely independently completed by our team. If we do not copy any of our existing Ethernet protocols (such as UIP/LWIP), we are afraid to refer to any of them. The Protocol structures are open as international standards, we only need to implement it according to the protocol.
Despise those who say they are plagiarized if they cannot!

The tinyip class generates random MAC addresses and initial IP addresses 192.168.0.x Based on the System ID. The last byte of the IP address is the first byte of the System ID.
After DHCP is enabled, the IP address is automatically obtained.
ARP must be implemented. Otherwise, the Mac corresponding to your IP address cannot be found and communication fails.
Supports attaching Ping, TCP, and UDP events.
All Ethernet functions are enabled. The firmware Rom in RTM is about 9 KB.
End.
