Hi guys,

I'm building a simulink application using UDP Receive Binary and UDP Send Binary blocks from Simulink Real Time (Matlab2015a). I'm trying to test a communication using a ethernet cable between simulink and my Beaglebone where I built a UDP server socket (IP : 10.10.10.99 / 51001). I'm able to send data to the Beaglebone but I'm unable to receive data from Beaglebone. I tried to open the wireshark to see what's going on and the data it is been sent to the my computer (IP : 10.10.10.1) but the UDP Receive binary block shows nothing.

On the UDP Send binary block, these are the configurations :

Destination IP address : 10.10.10.99 (Beaglebone's IP address)

Destination Port : 51001

Local (source) Port : 50000

Sample time : 0.01

On the UDP Receive Binary :

Source IP address : 10.10.10.99

Local (destination) port : 50000

Output port Width : 24

Sample time : 0.01

Can someone explain me why I can not recover the data using the UDP Receive Binary block?

Thank you.
