esp-idf/components/esp_netif_stack

ESP-NETIF stack component

This component is a direct dependency of ESP-NETIF and it defines a required dependency on lwIP.

Purpose

Purpose of this component is to pull specific TCP/IP stack (lwIP) into the list of dependencies when using component ESP-NETIF. By means of esp_netif_stack component, we can define these two dependency scenarios:

1. Defines a required dependency on lwIP via this component (default)
2. In case a non-lwip build is required.

Configure ESP-NETIF for building without lwIP

In order to use ESP-NETIF without lwIP (e.g. when using custom TCP/IP stack), follow these steps

• unselect CONFIG_ESP_NETIF_TCPIP_LWIP in esp_netif component configuration
• add a component esp_netif_stack to your private component paths
• register an empty component idf_component_register() in the component's CMakeLists.txt
