Integration of OV5640 camera into an ESP32-S3 using GDMA and the LCD_CAM peripheral

I am trying to integrate an OV5640 camera into an ESP32-S3 using GDMA and the LCD_CAM peripheral. This is the first attempt and the objective is to verify that the peripheral captures the data from the camera interface and using GDMA writes it to the list buffer. To check that everything works the D...

Re: Two instances of WiFiUDP

This works. #include "WiFi.h" #include "AsyncUDP.h" #include "Arduino.h" const char * ssid = "xxxxxxxxx"; const char * password = "yyyyyyyyyyyyy"; AsyncUDP udp; IPAddress multicast_address_1 = IPAddress(224, 1, 1, 1); uint16_t udp_port_1 = 6000; IPAddress multicast_address_2 = IPAddress(224, 1, 1, 1...

Re: Two instances of WiFiUDP

With "verbose logging" activated I can see something related to WiFi connection, nothing more.

About AsyncUDP I have tested two AsyncUDP instances and one AsyncUDP instance with two listenMulticast()
without any success.

I don't know what else I can do :(

Re: Two instances of WiFiUDP

Thanks but there is a compile error. IP address must be IPAddress type.
From WiFiUdp.h -> uint8_t beginMulticast(IPAddress a, uint16_t p);

Two instances of WiFiUDP

Hi, Is it possible create two instances of WiFiUDP with different multicast address ?. WiFiUDP Udp; IPAddress grupo_multicast(224, 1, 1, 10); int udpport = 6000; char datain[100]; WiFiUDP Udp_video; IPAddress grupo_multicast_video(224, 1, 1, 1); int udpport_video = 6000; char datain_video[1460]; voi...

I have tested with IDF 3.3 version and "ping hostname" works but network scanner apps like Windows "Advanced IP scanner" and Android "Fing" do not display the hostname. esp_err_t err = mdns_init(); if (err) { printf("MDNS Init failed: %d\n", err); } mdns_hostname_set("hostname"); mdns_instance_name_...
