Cannot establish a connection to Raspberry Pi 3

I'm working with MATLAB R2018b with support package for raspberry pi; Windows 10; Raspberry Pi 2 B & 3 Model B+.

When I try to connect to my RPi for the first time after installing raspbian_R18.2.0, I get an timeout or connection error after "### Lauching MATLAB I/O server".

I've tried two different SD Cards and two Raspberry Pi's. All give me the same result.

Cannot establish a connection to the board with device address "xxx.xxx.xxx.189". Wait 30 seconds and try again.

Did anybody have an idea how to fix that?

Thanks a lot!

Can you try to disable Windows Firewall and try to connect again?

[Ming Yue]

Also, when you first installed Rasbian, the default login is username=pi, password=raspberry, can you also try creating raspi object with this:

>> r=raspi('xxx.xxx.xxx.189','pi','raspberry'); %replace with your board's IP

Having the same issue as Felix. Disabled the firewall.

Matlab/Simulink are able to deploy models. I can ping through cmd, and connect via ssh.

The problem is through the raspi only.

r = raspberrypi works... and the targetHardware('Raspberry Pi') as well.

Thanks a lot guys. At the moment I'm not able to check that. But I had a similar problem which I solved that way. So I'm pretty sure that disabling the windows firewall will solve the connection problems.
