Re: [Solved]UART rx ISR not working

Dont forget to call usr_isr_free before uart_isr_register

Code: Select all

// release the pre registered UART handler/subroutine
    ESP_ERROR_CHECK(uart_isr_free(EX_UART_NUM));

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 does not detect modem disconnection

Hi all, I am simulating a signal loss by removing the antenna from the modem and I keep sending packets to a server using TCP socket. 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().
