I'm currently trying to connect my Arduino Portenta H7 to a Socket.IO server, but I'm unable to establish a connection.
Arduino code:
#include <SPI.h>
#include <Ethernet.h>
#include <ArduinoHttpClient.h>
// Enter a MAC address and IP address for your controller below.
// The IP address will be dependent on your local network:
byte mac[] = {
0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED
};
IPAddress ip(10, 0, 0, 100);
EthernetClient ethernet;
char serverAddress[] = "10.0.0.14/socket.io/?EIO=4&transport=websocket"; // server address
int port = 8080;
WebSocketClient client = WebSocketClient(ethernet, serverAddress, port);
int count = 0;
void setup() {
// Open serial communications and wait for port to open:
Serial.begin(9600);
while (!Serial) {
; // wait for serial port to connect. Needed for native USB port only
}
Serial.println("Ethernet WebServer Example");
// start the Ethernet connection and the server:
Ethernet.begin(mac, ip);
// Check for Ethernet hardware present
if (Ethernet.hardwareStatus() == EthernetNoHardware) {
Serial.println("Ethernet shield was not found. Sorry, can't run without hardware. :(");
while (true) {
delay(1); // do nothing, no point running without Ethernet hardware
}
}
if (Ethernet.linkStatus() == LinkOFF) {
Serial.println("Ethernet cable is not connected.");
}
}
void loop() {
Serial.println("starting WebSocket client");
client.begin();
while (client.connected()) {
Serial.print("Sending hello ");
Serial.println(count);
// send a hello #
client.beginMessage(TYPE_TEXT);
client.print("hello ");
client.print(count);
client.endMessage();
// increment count for next message
count++;
// check if a message is available to be received
int messageSize = client.parseMessage();
if (messageSize > 0) {
Serial.println("Received a message:");
Serial.println(client.readString());
}
// wait 5 seconds
delay(5000);
}
Serial.println("disconnected");
}
Socket.IO Example Server:
import socketio
from aiohttp import web
sio = socketio.AsyncServer()
app = web.Application()
sio.attach(app)
async def index(request):
with open("index.html") as f:
return web.Response(text=f.read(), content_type="text/html")
@sio.on("*")
def catch_all(event, sid, data):
print("Socket ID: ", sid)
print(data)
app.router.add_get("/", index)
if __name__ == "__main__":
web.run_app(app)
Versions:
- python-socketio: 5x
- Engine.IO: 4
- Socket.IO 5
I also tried using arduinoWebSockets, but I couldn't get it to work with the Arduino Portenta H7. Any help is greatly appreciated.
