Hi all,

I would like to use a few teensys with OSC.

With my current setup, the helpful guidelines, and the attached code, I am able to receive OSC messages on my laptop from the Teensy. But, after fiddling around and looking at the forums, I am still not able to receive OSC messages from my max/patch to my Teensy 3.2(although the IP and port are a match).

Here is my current setup:

I have a USB to Ethernet adaptor (from apple) that connects my WIZ820io ethernet module with my computer. I successfully wired the WIZ820io ethernet module with my Teensy 3.2 on a breadboard, according to the guideline on Teensy's website. The teensy is powered through USB and the ethernet module with an external power supply. The grounds are connected.

I have attached a few images and the code I am currently using to test, in case it is of help.
I would really appreciate it if anybody has any insights or solutions for the problem I am currently facing.

Here is the code I am using for the Teensy:

#include <OSCMessage.h>
#include <Ethernet.h>
#include <EthernetUdp.h>
#include <SPI.h>    
#include <OSCMessage.h>
#include <OSCBundle.h>
#include <OSCBoards.h>

#pragma GCC diagnostic ignored "-Wwrite-strings"
/*******************SETUP OSC********************/
EthernetUDP Udp;
// is the IP to broadcast to all devices in the network
IPAddress ip(10, 0, 1, 2);
IPAddress outIp(10, 0, 1, 1); //destination IP
const unsigned int outPort = 6789;
const unsigned int inPort  = 8979;
byte mac[]                 = { 0x04, 0xE9, 0xE5, 0x03, 0x94, 0x5E }; // you can find this written on the board of some Arduino Ethernets or shields, for Teensy we have custom made code - implement it

void setup() {

void loop(){
  //the message wants an OSC address as first argument
  sendOSCMessage("/speed", 2, outIp, outPort);

void sendOSCMessage(char *addr_pattern, int mtr_id, IPAddress ip_, int port_){

  OSCMessage msg_recv(addr_pattern);
  Udp.beginPacket(ip_, port_);
  msg_recv.send(Udp); // send the bytes to the SLIP stream
  Udp.endPacket(); // mark the end of the OSC Packet
  msg_recv.empty(); // free space occupied by message

void OSCMsgReceive(){
   OSCBundle bundleIN;
   int size;

   if( (size = Udp.parsePacket())>0)

        bundleIN.route("/input", inputfunction);

void inputfunction(OSCMessage &msg, int addrOffset){
  int value = msg.getInt(0);
  Serial.print("Value = : ");
Here is the max patch:
