I'm having some issues getting my BeagleBoneBlack (BBB) to talk with my Arduino ethernet shield.
The BBB is running Java and I'm using standard sockets to write/read a message on the UDP port.
The following setups work:
Java (BBB) -> Packet Sender (on windows PC) : Packets are successfully sent and received
Java (on Windows PC) -> Arduino Ethernet shield : Packets are successfully sent and received
Arduino Ethernet shield -> Packet Sender (on windows PC) : Packets are successfully sent and received
Java (BBB) -> Arduino Ethernet shield : !!! FAIL !!! Cannot get the two to talk to each other.
Anyone have any idea as to why I can get my pc running java to talk with the Ethernet shield but the BBB running the SAME program
refuses to talk (A connection is established though as far I understand. It throws and error when there is no physical connection).
Details:
I'm deploying the BBB remotely from my PC through Netbeans through USB and the BBB is connected to the ethernet shield through classical ethernet cable.

Java:
try {
System.out.println("Waiting for packet from SYSCU...");
BUFFER = new byte[3];
// Receive request
PACKET = new DatagramPacket(BUFFER, BUFFER.length);
SOCK.receive(PACKET);
// Print out received message
String msg = new String(BUFFER, 0, PACKET.getLength());
System.out.println("Message received from SYSCU: " + msg);
Snippet running on arduino:
C:
void setup() {
Ethernet.begin(mac,ip);
Udp.begin(localPort);
Serial.begin(9600);
while(1){
char str[3];
str[0] = 'a';
str[1] = 'c';
str[2] = 'k';
// Send a new packet
Udp.beginPacket(remoteIP, remotePort); // localPort
Udp.write(str);
Udp.endPacket();
Serial.println("Packet sent, waiting 1000ms ");
delay(1000);
}
Thanks in advance.
