Async client example

[Boguinhos]

Hello there! I’m self learning on how to program and i’m trying to go async on a little project i have but i’m struggling with this library as the example provided is not something i can fully understand. But i found this old example on the issues (from 2016) that i got working. But i think i’m not going the right way. I need to make a get request for like 4 to 10 sequencial local ips as fast as i can. The request is as basic as it gets as i don’t need the reply, just to send the get request and if i could i would discard the server’s reply if that could make it faster. I think i made it work by cheating as this routine checks if aClient exists and if it does it returns. As i need to send several fast requests and i only was able to complete one, i removed the object existance validation so that i could use the same object for all the iterations i need. And it worked. But it’s speed is not constant, sometimes it seems fast but next time it can be not so fast. I do not get consistant results. I was thinking on creating a new async client object for each request but as the number of requests i need should be dynamic i think i cannot make new objects in a for loop. How could i make several fast requests?

This is the example i got: ' static AsyncClient * aClient = NULL;

void runAsyncClient(){ if(aClient)//client already exists return;

aClient = new AsyncClient(); if(!aClient)//could not allocate client return;

aClient->onError([](void arg, AsyncClient client, int error){ Serial.println("Connect Error"); aClient = NULL; delete client; }, NULL);

aClient->onConnect([](void arg, AsyncClient client){ Serial.println("Connected"); aClient->onError(NULL, NULL);

client->onDisconnect([](void * arg, AsyncClient * c){
  Serial.println("Disconnected");
  aClient = NULL;
  delete c;
}, NULL);

client->onData([](void * arg, AsyncClient * c, void * data, size_t len){
  Serial.print("\r\nData: ");
  Serial.println(len);
  uint8_t * d = (uint8_t*)data;
  for(size_t i=0; i<len;i++)
    Serial.write(d[i]);
}, NULL);

//send the request
client->write("GET / HTTP/1.0\r\nHost: www.google.com\r\n\r\n");

}, NULL);

if(!aClient->connect("www.google.com", 80)){ Serial.println("Connect Fail"); AsyncClient * client = aClient; aClient = NULL; delete client; } }'

Thank you!
