Send data to Processing (serial port) via BLE or WiFi

Natriumcyanid · May 24, 2022, 6:42pm

Hello, I'm trying to send data from a sensor to a Linux PC wirelessly, with use of the Nano 33 IoT,
and I want to use that data immediately in a Processing program.
I could read it from a serial port in the Processing program, if I somehow sent it to one, either via Bluetooth or WiFi.

Is there a way to do this, or could there be another way?

Hi,

I have a processing sketch here which I experimented with a while back where it acts as a web server which could be modified so your Arduino could send data to it via a http request?

github.com

  // processing sketch to trigger events upon HTTP requests received - 10Jan23
  
  // trigger with       http://localhost?trigger1      or       http://localhost?trigger2
  
  // ---------------------------------------------------------------------------------
  // original code from: https://processing.org/discourse/beta/num_1231628867.html

import processing.net.*;

String HTTP_GET_REQUEST = "GET /";
String HTTP_HEADER = "HTTP/1.0 200 OK\r\nContent-Type: text/html\r\n\r\n";

Server s;
Client c;
String input;

void setup() 
{
  // set up display window
