Core Panic about arduinoosc

[devinroth]

I just tried out a different ESP32 board and it doesn't crash. There must be something wrong with the other board. Thanks for you help.

Could you give me more information?

• source code
• esp32-arduino version
• Arduino IDE or PlatformIO and version
• ArduinoOSC version
• etc.

[devinroth]

Source: ArduinoOSC OscWIFi example program.
Esp32-arduino version: 1.0.1
Arduino IDE 1.8.9
ArduinoOSC version: 0.2.1

The board sends OSC messages just fine. It's only when receiving that it crashes. It seems to be related to the callback. It receives data just fine if I don't use a callback.

mmm... in the same configuration, my examples works fine w/ Max8.
Let me know more information:

• Is arduino-esp32 repo in the latest master branch??
• Which program do you use to send OSC?
  Thank you for your cooperation!

Let me add :

• Please give a source code. (Delete your WiFi info plz ;))

First off, thanks for helping. I'm pretty sure this problem is an ESP32 issue not a ArduinoOSC problem but let's try to get to the bottom of the problem.

Maybe there's a problem with the board. I have another ESP32 I can try it on later today.

I installed the arduino-esp32 with the board manager in the IDE as recommended. https://github.com/espressif/arduino-esp32

I'm using my own program SwiftOSC to send data. I even tried sending identical data to the board as you send out in the example code with the same problem. So I know for a fact it's not a formatting issue.

I'm using your OscWifi example with only changing Wifi info. I tried commenting out all the code in the callback so it happens somewhere between receiving the data and calling the callback.

#include <ArduinoOSC.h>

// WiFi stuff
const char* ssid = "your-ssid";
const char* pwd = "your-password";
const IPAddress ip(192, 168, 1, 201);
const IPAddress gateway(192, 168, 1, 1);
const IPAddress subnet(255, 255, 255, 0);

// for ArduinoOSC
OscWiFi osc;
const char* host = "192.168.1.200";
const int recv_port = 10000;
const int send_port = 12000;

void onOscReceived(OscMessage& m)
{
    Serial.print("callback : ");
    Serial.print(m.ip()); Serial.print(" ");
    Serial.print(m.port()); Serial.print(" ");
    Serial.print(m.size()); Serial.print(" ");
    Serial.print(m.address()); Serial.print(" ");
    Serial.print(m.arg<int>(0)); Serial.print(" ");
    Serial.print(m.arg<float>(1)); Serial.print(" ");
    Serial.print(m.arg<String>(2)); Serial.println();
}

void setup()
{
    Serial.begin(115200);

    // WiFi stuff
    WiFi.begin(ssid, pwd);
    WiFi.config(ip, gateway, subnet);
    while (WiFi.status() != WL_CONNECTED) { Serial.print("."); delay(500); }
    Serial.print("WiFi connected, IP = "); Serial.println(WiFi.localIP());

    // ArduinoOSC
    osc.begin(recv_port);

    // TODO: TBD
    // osc.subscribe("/int32", i);
    // osc.subscribe("/float", f);
    // osc.subscribe("/string", s);
    // osc.subscribe("/blob", b);

    osc.subscribe("/callback", onOscReceived); // old style (v0.1.x)

    osc.subscribe("/lambda", [](OscMessage& m)
    {
        Serial.print("lambda : ");
        Serial.print(m.ip()); Serial.print(" ");
        Serial.print(m.port()); Serial.print(" ");
        Serial.print(m.size()); Serial.print(" ");
        Serial.print(m.address()); Serial.print(" ");
        Serial.print(m.arg<int>(0)); Serial.print(" ");
        Serial.print(m.arg<float>(1)); Serial.print(" ");
        Serial.print(m.arg<String>(2)); Serial.println();
    });
    osc.subscribe("/wildcard/*/test", [](OscMessage& m)
    {
        Serial.print("wildcard : ");
        Serial.print(m.ip()); Serial.print(" ");
        Serial.print(m.port()); Serial.print(" ");
        Serial.print(m.size()); Serial.print(" ");
        Serial.print(m.address()); Serial.print(" ");
        Serial.print(m.arg<int>(0)); Serial.println();

    });
    osc.subscribe("/need/reply", [](OscMessage& m)
    {
        Serial.println("/need/reply");

        int i = 12;
        float f = 34.56F;
        double d = 78.987;
        String s = "hello";
        bool b = true;

        osc.send(host, send_port, "/send", i, f, d, s, b);
    });

    // TODO: TBD
    // osc.publish(host, send_port, "/value", value);
    // osc.publish(host, send_port, "/millis", &millis);
}

void loop()
{
    osc.parse(); // should be called
}

I should add that I don't think it's a parsing problem. It doesn't crash when data is received and I don't get an error from the parser..
