[ripleyXLR8]

Hi,

Thank you for your work on this library, it is very usefull.

Do you have any example about using the AsyncPrinter?

Best regards

disclaimer: i am not at all proficient in c++, but here is how i got it to work in combination with WiFiManager to establish a wifi connection first:

#include <DNSServer.h>            //Local DNS Server used for redirecting all requests to the configuration portal
#include <ESP8266WebServer.h>     //Local WebServer used to serve the configuration portal
#include <WiFiManager.h>          //https://github.com/tzapu/WiFiManager WiFi Configuration Magic
#include <AsyncPrinter.h>

AsyncPrinter ap;
WiFiManager wifiManager;
 
void setup() {
  // put your setup code here, to run once:
  Serial.begin(115200);
  wifiManager.autoConnect();
  ap.connect("192.168.1.122",3333);
  ap.println("hello world");
}
 
void loop() {
  // put your main code here, to run repeatedly:
}

on the computer with ip 192.168.1.122 you need to listen to port 3333 to receive the hello world message. under linux you can use netcat:
nc -l 3333

now upload and run the above sketch and you should see "hello world" printed to your console running netcat.

Update: i noticed only after posting this, that the AsyncPrinter::connect() function blocks forever if it cannot connect to the given IP or Hostname. In order to avoid this you would need to modify the
while(_client->state() < 4)
loop in the connect function, or you simply remove it and then let your sketch handle the waiting.
