Cant Convert Unicast to MultiCast.

Postby DutchOrange » Fri Jan 08, 2021 3:41 pm

So I have this code that was from a unicast example that I found and worked very well but now I would like to make it into Multicast mesh. You will see there are many attempts of where I have tried to make it into Multicast. This is the current code that works for unicast:
Thanks for any help.

Code: Select all

#include <string.h>
#include "freertos/FreeRTOS.h"
#include "freertos/task.h"
#include "freertos/ringbuf.h"
#include "esp_log.h"
#include "sdkconfig.h"

#include "mdf_common.h"
#include "mwifi.h"

#include "driver/gpio.h"

// sense_main.c
// Light_example.c
// aliyun_mdf.c
// ret = mwifi_root_write(dest_addrs, dest_addrs_num, &data_type, data, size, true);  //THIS ONE ? ???? ?
//mwifi.c    IS WHAT U NEED

// #define MEMORY_DEBUG

static const char *TAG = "ROOT";

    mdf_err_t ret                  = MDF_OK; 
    mwifi_data_type_t data_type    = {0};
    //mwifi_data_type_t data_type    = {MWIFI_COMMUNICATE_MULTICAST};
    data_type.communicate = MWIFI_COMMUNICATE_MULTICAST;    //Type of Transmission 
    // const uint8_t group_id[MWIFI_ADDR_LEN] = {0xa8, 0x03, 0x2a, 0xc0, 0x46, 0x44};   //MWIFI_ADDR_LEN Is the Mac Adress
