Code: [Select all] [Expand/Collapse]

while(true){
        if(status == WIFI_CONNECTED){
            //the raw buffer len must be <= 1500 Bytes and >= 24 Bytes
        err = esp_wifi_80211_tx(WIFI_IF_AP, ds2ds_pdu, sizeof(ds2ds_pdu), true);
        ESP_LOGE(TAG, "Send wifi data. (%s)", esp_err_to_name(err));   
            //sys_delay_ms(1000);
        }
    else{
        sys_delay_ms(5000);
        printf("continue... \n");
    }
    }

This is the code for sending wifi data frame continuously. But I can't get the ideal rate because of the err "(ESP_ERR_NO_MEM)". The result as follow. How can I resolve this question? The actual valid rate is about 720kbps which is too low. Why does the API "esp_wifi_80211_tx" send data so slowly?
Thanks for anyone answer my question!
