ESP32 ethernet no ETH.end / disable

[doyoon.kim]

I'm working on a project based on ethernet communication via ESP32 + LAN8720 module

I set up a static IP right after booting and proceed with certain tasks, and a sequence is needed to change the dynamic IP.

In ETH.H/CPP there is a begin method but no corressponding end method.

I am going to make ETH.END and use it in the process of changing static IP to dynamic IP.

ETH.END implementation ( ETH.CPP)

Code: [Select all] [Expand/Collapse]

1. esp_netif_t *g_eth_netif = NULL;
2.  
3. bool ETHClass::end()
4. {
5.    esp_err_t err;
6.    eth_link = ETH_LINK_DOWN;
7.  
8.    if(eth_handle != NULL)
9.    {
10.       err = esp_eth_stop(eth_handle);
11.  
12.       if (err)
13.       {
14.          log_e("esp_eth_stop error: %d", err);
15.          return false;
16.       }
17.    }
18.  
19.    if(g_eth_netif != NULL)
20.    {
21.       /* These default interfaces must not be created multiple times, unless the created handle is deleted using esp_netif_destroy().*/
22.       esp_netif_destroy(g_eth_netif);
23.       g_eth_netif = NULL;
24.    }
25.  
26.    started = false;
27.  
28.    return true;
29. }

STAIC IP -> ETH.end -> Dynamic IP

I want to do this, but it is not working normally
please help me
