Change ethernet IP address?

I am trying to change (not 'set') the IP address on the ethernet connection, like this: esp_err_t dnet_set_addr(char *str) { esp_netif_ip_info_t eth_info = {0}; if (dnet_str2ip4(ð_info.ip, str)) { return esp_netif_set_ip_info(eth_get_netif(), ð_info); } else { return -1; }; } because this: htt...

Re: Developing with ESP-IDF under WSL2

Note: WSL2 also is unable to connect to PCI cards (pcie, pci-x and pci express). Including serial-port cards. The solution is the same: install a network serial port virtualization program on client and host.

"ESP_DHCP_DEBUG" is undeclared", problem building with docker container esp-idf 4.1.3

Using "docker pull espressif/idf:v4.1.3", when I try to build I get a series of errors "ESP_DHCP_DEBUG" is undeclared for example: /opt/esp/idf/components/lwip/lwip/src/core/ipv4/dhcp.c:292:15: error: 'ESP_DHCP_DEBUG' undeclared (first use in this function); did you mean 'DHCP_DEBUG'? Have I done so...

Is 'rollup' a part of the standard tools and build environment?

I'm trying to use expressif idf v4.1.2 to build a project I've inherited, like this: docker run --rm -v f:\projects\myproject\firmware :/firmware -w /firmware -it espressif/idf:v4.1.2 That command finds the espressif idf container tagged v4.1.2 and creates an image linked to my firmware folder. When...

Re: Build with AutoIP not working as expected (at all)

I've avoided the problem by changing the GARP interval from 60 seconds to 14 seconds, thus eliminating the requirement in my network to send ARP requests. Win10/Server 2016 uses the (IPv6) neighborhood table rather than an ARP cache. Network traffic suggests that Windows is setting the table entry t...

Is it an ARP problem? An AutoIP problem? A problem with the multi-homed stack? Or has the stack cra...

Build with AutoIP not working as expected (at all)

I included AutoIP, (IPV4 link-local, Automatic Private IP Addressing) in the build I've inherited, and it's not working as expected. Wireshark shows ARP probe then Gratuitous ARP, as expected, and the GARP is repeated periodically, as expected, but the device does not respond to ARP for the advertis...

IPV4 link-local, Automatic Private IP Addressing (169.254.x.x)

Does the Espressif network stack support IPV4 link-local addressing? If so, how do you configure/enable it?

I've just inherited a IDF project. I see that lwip has autoip.h, but I've no idea how to include that in the IDF project, or if it is necessary or possible.
