webclient GET not blocking

[storchalberto]

I think it would be useful to have a non-blocking function equivalent to .GET until the response, so as not to block the system until the response arrives and to subsequently be able to verify the arrival of the response via get_size. It would therefore also be necessary to implement a function that allows you to recover the HTTP result when the get_size returns a value other than -1

Just to be sure to understand your question
You are talking about Berry's WebClient ?
What you basically would like is an async mode with a call back ?

[storchalberto]

Yes. a call back will be the best, but if not possible, a non blocking get and a function (used inside a timer function) that allow to test the result

There is a minimalistic async web client implemented for Matter bridge support. But it's primarily designed for Tasmota http, so very limited in features.

Did you create an instance of udp_listener?

[storchalberto]

No. where is the documentation?

[sfromis]

Needing to create an instance after having defined a class is a very basic thing to doing programming with classes. Not doing it is like not running a program, but still expecting it to act.

OK, here the code on the ESP32 192.168.1.77

class udp_listener
  var u
  def init(ip, port)
    self.u = udp()
    print(self.u.begin("",2000))
  end
  def every_50ms()
    import string
    var packet = self.u.read()
    while packet != nil
      tasmota.log(string.format(">>> Received packet ([%s]:%i): %s", self.u.remote_ip, self.u.remote_port, packet.tohex()), 2)
      packet = self.u.read()
    end
  end
end
d1 = udp_listener()
tasmota.add_driver(d1)

On the consolle i see: true.
here the code on ESP32 192.168.1.22

u = udp()
u.begin("", 2000)    # listen on all interfaces, port 2000
u.send("192.168.1.77", 2000, bytes("414243"))   # send 'ABC' to 192.168.1.77:2000, source port is 2000

I do not see on 192.168.1.77 the data received

[s-hadinger]

The example above works perfectly fine:

20:03:35.169 >>> Received packet ([192.168.2.210]:2000): 414243

I suspect that you are looking at the Berry console. Since you use tasmota.log(), it is not displayed in the Berry console but in the Tasmota console.
