require TCP/IP reference code for nrf7002

[ChiragBhavsar]

In DevAcademy, I referred to Lesson 3 – Networking & Sockets, but I couldn't find reference code related to TCP/IP.

Please provide me with this reference code.

Hi,

I used the macros below in prj.conf for TCP/IP. Are they correct, or should I add or remove any macros?

CONFIG_NETWORKING=y

CONFIG_NET_NATIVE=y

CONFIG_NET_SOCKETS=y

CONFIG_NET_SOCKETS_POSIX_NAMES=y

CONFIG_POSIX_MAX_FDS=16

CONFIG_NET_L2_ETHERNET=y

CONFIG_NET_IPV6=y

CONFIG_NET_IPV4=y

CONFIG_NET_DHCPV4=y

CONFIG_NET_TCP=y

CONFIG_DNS_RESOLVER=y

Hi,

You only need to make a few changes to get lesson 3 exercise 1 to connect to a TCP server instead of UDP.

1. Add CONFIG_NET_TCP=y in prj.conf.

2. Change the two instances of SOCK_DGRAM to SOCK_STREAM.

3. Change IPPROTO_UDP to IPPROTO_TCP in the socket() function.

Make sure to also change the server address and port.

If you get a secure fault when connecting to the server, you might have to set CONFIG_NET_IPV6=n in prj.conf.

Best regards,
Marte
