      Thanks, @robolink_leila!

      Is it possible to SSH into Zumi in this state (dashboard not working)?

        @indrajaal Oh no! ๐Ÿ˜ž Thanks for your feedback. I am going to ask our software engineer what the issue may be and possibly he can get us a test script to run on your Pi. When I get a solution, I'll ask you to set up another support call to run a diagnostic. Thanks for all your patience!

          @robolink_leila @robolink_wes any guidance, please, on how to proceed here?

            @robolink_leila following up on my previous post, now, it seems the dashboard is bricked somehow.

            After I connect to Zumi and it starts to show the Go to zumidashboard.ai in your browser message, I can't load the dashboard anymore ๐Ÿ˜ญ.

            I tried doing a full DNS flush and reconnecting, but no dice.

            sudo killall -HUP mDNSResponder;sudo killall mDNSResponderHelper;sudo dscacheutil -flushcache

            Are there any application logs I can look at/post here? Not sure how the dash is implemented, but, maybe the server powering it has died and just needs to be restarted?

              Hey, @robolink_leila

              I received the new Pi Zero today, assembled it, and now Zumi comes up properly. However, it's now unable to connect to my WiFi ๐Ÿ˜ž

              I can see from my router (Comcast Router: Cisco DPC3941T) admin console, that it's trying to connect to the 2.4GHz n/w.

              I am, though, able to run the example Jupyter notebooks in Offline mode.

              Another thing I noticed was that only the Demo and Tutorials buttons are active in Offline mode. Is that expected?

                @indrajaal We will have a RaspberryPi Zero on the way for you this week!

                  Hey @robolink_leila, thanks so much for the support call the other day. Based on the call, I was able to confirm that the RPi Zero is able to boot up, but gets stuck trying to acquire a WiFi address, just as was anticipated.

                  So, the issue definitely seems to be with its WiFi module.

                    Thank you, @robolink_leila! I setup a support call for this Thursday, 2:00 โ€“ 2:30pm.

                      @indrajaal Most likely it's the RaspberryPi but if you are available for a support call it would help us get some feedback and figure out the next steps. Thank you!

                        Hi, @robolink_leila

                        I recently received my Zumi ( backer 580), and after assembling it, I'm facing the same issue. After powering it up, it remains stuck at the Loading... step.

                        I've already followed this tutorial and re-flashed it to no avail. I did notice that the image linked to in the video has the name img_0719.img, so maybe it's not the latest? I can try another re-flash if there's a newer image available.

                        Please help!

                          @frankensusan Check out the San Diego Robotics Club on meetup.com! We don't host all of the events, but it's a great community of robot enthusiasts.

                            @robolink_leila Thank you so much for the amazing support visit.
                            My wee little Zumi is up and running, with updates. So super cute.

                            Side question, how can I keep informed about local events where Robolink will be participating?

                              @robolink_leila I sure will itโ€™ll be heading your way. Iโ€™m sure thatโ€™s what it is because I didnโ€™t change anything but the pi and it started working. The GPIO header looked ok without any solder shorting across pins.

                                  @frankensusan I will also be sending you information about scheduling a support call. These are unknown issues and we have our team working on them but we may need some more information. Thanks!

                                    @robolink_leila I did get mine working by swapping out the R Pi Zero. I had one around here that I had to find first and then had to solder a GPIO header on it. But the R P Zero was my problem. So how can we go about swapping the bad Pi that came with the Zumi out?

                                            @sealfish Could you attach an image of all the wiring? We may need to do a support call with you. I will send you an email to the email associated with this forum account with the information where you can schedule a support call. Thank you!
