Re: Getting netif

Hi,

How do I set Wifi as default interface?

Code: Select all

void setWifidefault()
{
    esp_netif_t* netif = NULL;
    netif = esp_netif_get_handle_from_ifkey("WIFI_AP_DEF");
    netif_set_default(netif->lwip_netif);
}
error: dereferencing pointer to incomplete type 'esp_netif_t' {aka 'struct esp_netif_obj'}

PPP might detect connection loss, but TCP won't. That's expected, unless
you use LWIP_TCP_KEEPALIVE (just gxxxle for tcp keepalive...).

After remove the antenna, the function lwip_send() wont fail and error number is not set too. I was expecting TCP layer to detect the lack of TCP ACK or PPP should ha...

ESP32 sleep mode and resume the code

We are creating an application that needs to save power so we are putting the ESP32 into deep sleep, and using the ULP co-processor to wake up on a pin change, or to wake up after a predetermined amount of time i.e. 1hr so we can turn on sensors, collect the data, send it to a server via cellular mo...

Hi guys,

I have same problem, and I am using SD MMC mode. I solved by calling taskYIELD() after fwrite().
