I am running firmware version 1.09E on my EV3 and I can ping it from my laptop and from Matlab using !ping. But Simulink won't connect to it. Please help!
Output below:
>> !ping 10.1.1.16
PING 10.1.1.16 (10.1.1.16) 56(84) bytes of data.

Is it possible that the ev3's ID is something different? Is it possible that the connection is not wifi ? After you do the ping, what shows up if you then
!arp -a
in particular does 00:16:53:51:fa:52 show up and if so against which interface name?

Hi Krish,
In the firmware version V1.09, the SSH and telnet are blocked by Lego. The interface Simulink uses to connect to the brick relies on these two types of connections. A workaround is to use an older firmware version, for example, V1.03.
