9.2.2 Network Stack

The network stack features are as follows:

• Integrated IPv4, IPv6, and TCP/IP stack with BSD socket APIs for simple Internet connectivity with any MCU,

microprocessor, or ASIC

Note

Not all APIs are 100% BSD compliant. Not all BSD APIs are supported.

• Support of 16 simultaneous TCP, UDP, RAW, SSL\TLS sockets
• Built-in network protocols:

– Static IP, LLA, DHCPv4, DHCPv6 (Stateful) with DAD and Stateless auto configuration
– ARP, ICMPv4, IGMP, ICMPv6, MLD, ND
– DNS client for easy connection to the local network and the Internet

• Built-in network application and utilities:

– HTTP/HTTPS

• Web page content stored on serial Flash
• RESTful APIs for setting\configuring application content
• Dynamic user callbacks

• Service discovery: Multicast DNS service discovery allows a client to advertise its service without a

centralized server. After connecting to the access point, the CC3135 device provides critical information,
such as device name, IP, vendor, and port number.

• DHCP server
• Ping
