Mathematica RDK does not connect to the Raspberry Pi

Cliff,

There is some indication that the wolframssh.jar file in Windows version 10 of mathematica is faulty. I have encountered a similar issue and fortunately have access to wolframssh.jar from version 9. The other suggestion, to use Cygwin's ssh instead of wolframssh.jar, apparently works, but I cannot vouch for it since I haven't personally tried it.

Bob, thank you for letting us know.

Bob, Thanks for the info. Unfortunately, swapping out the Wolfram ssh with the Cygwin version appears to be getting a little deeper than my knowledge of Mathematic enables me to go. I'll just get by with the RPi notebook interface remoted to my Win 7 machine via X for awhile and revisit this when the next upgrade to Mathematica comes along.

Thanks very much for the suggestions. Let me clarify just a couple things.

On my Win 7 machine, my version of Mathematica is 10.0.2.0. I'm not aware of a newer version. I know the IP address I am using is correct as I separately login to the RPi with it via ssh. I am NEVER prompted to enter a password. Instead I get the error I posted earlier in a popup dialog after a pause of about 10 seconds. Again that is:

SSH's connection for kernel 'Raspberry Pi' was unexpectedly terminated. Error code = 103.

My kernel configuration options looks like the following. Kernel Configuration Options

The main difference I see is that mine has an additional advanced option for shell command.

I should also point out that I assume my actions on the Win 7 machine will launch mathematica on the RPi. If this is not the case, please let me know the options the "wolfram" command needs on the RPi.

Thanks again Cliff

I've tested the Remote Development Kit and it works great for my Raspberry Pi 2. It's easy to get the wrong IP address, so make sure that you are using the right one. To check this type in your RPi terminal:

sudo ifconfig

and take note of the "inet addr:" in wlan0 (while using a USB WiFi adapter).

The next step is to introduce the right password ("raspberry" by default):

password

The "Pi Test & Example Notebook" should look like this:

raspi kernel Connected

Finally, if the problem persists, go to Evaluation > Kernel Configuration Options... and check that you entered the right parameters, it should look like this:

I too fail to connect to my RPi via the RDK, but with a different error.

Configuration: RPi 2 model B running Raspbian debian 7.8 Win 7 PC with Mathematica 10 Wolfram RDK installed with no errors Mathematica runs on RPi ok I can ssh from Win 7 PC to RPi with Cygwin providing the ssh client on PC I open the RDK from the Mathematica palettes menu and configure it with IP address of RPi and username=pi, but this information is never saved and shows up blank upon opening the configuration again. When I evaluate the test notebook, there is no dialog asking for the password. After a couple of seconds this error appears: SSH's connection for kernel 'Raspberry Pi' was unexpectedly terminated. Error code = 103.

I feel like I must be missing something simple. Any suggestions would be most welcome. Cliff

I would like to report Remote Develop Kit status. My environment is Mathematica 10.0.2.0 on Mac Mavericks. 

Can not connect with RDK     Raspberry Pi 2    10.0 for Linux ARM(32bit) (Febuary 3, 2015)
Can connect with RDK         Raspberry Pi      10.0 for Linux ARM(32bit) (August 4, 2014)

I hope the new RDK updates.

I have the same setup and same problem trying to connect through the rdk dialog interface. One extra wrinkle: even though I know the correct IP address for my pi, I cannot ssh to it either. SSH server is installed and running on the pi, but can't ping it either. Stymied....
