@robolink_leila I finally got around to testing the new image, and it worked!
I was also able to update to the latest firmware (v1.41 at the time of writing) via the WiFi!
Thanks for all the help!

RE: Loading....posted in Zumi
@robolink_leila connecting to the Hotspot on my iPhone 11 also did not work.

RE: Loading....posted in Zumi
Thanks, @robolink_leila! I'll try connecting to my iPhone's hotspot today. Don't have any other n/w to try. And, I'll try the new image once available.
Any idea why the Drive/Code modes are disabled in the dash? Is this expected?

RE: Loading....posted in Zumi
@robolink_leila upon restarting Zumi, I'm able to bring up the dash. However, Wi-Fi still doesn't work. I ran the command, disconnected from Zumi, reconnected and tried connecting via the dash, but to no avail
pi@zumi8753:~ $ sudo sh /bin/rpi-wifi.sh; echo $? Starting Wifi AP and client... wpa_supplicant: /sbin/wpa_supplicant daemon failed to start run-parts: /etc/network/if-pre-up.d/wpasupplicant exited with return code 1 ifup: failed to bring up wlan0 net.ipv4.ip_forward = 1 0
Driver/Code modes disabled?

RE: Zumi dashboard will not find wifiposted in Zumi
@sbanas I'm following up on a similar issue in this thread: https://forum.robolink.com/topic/386/loading/23.
May be of help.

RE: Loading....posted in Zumi
@robolink_leila so, several interesting things to note:
- The dashboard is somehow broken, but I am able to navigate to the notebooks, like http://zumidashboard.ai:5555/tree/Zumi_Content/Demo. It's just that navigating to zumidashboard.ai somehow doesn't work.
- After starting an SSH session, I figured out the PID for the main Zumi process, and attached to it via
straceas I wanted to see if I could see the messages it's writing tostdout. Interestingly, as soon as I attached to the process, the dashboard started working
! So, I went thru the process of scanning the WiFi n/w, selecting my SSID, entering the password and hitting Connect. It still continues to fail to connect 
. This is the log for that entire process, not sure if it helps any:

working again. Re-attaching didn't help.
Is there, perhaps, a better way to capture the logs? Does this look like an RPi Zero WiFi issue again? Is there a way I could just run the commands Zumi is running directly from a terminal to see if it's able to connect to my WiFi?
Another thing is that even though my router has both
2.4GHzand5GHzn/ws, they have the same name. Could that be the problem? I tried temporarily renaming one of them toNetwork-2G. After thatNetworkandNetwork-2Gshow up, but then other stuff on my n/w like my Chromecast etc stop working
.Anyway, I'll keep digging. I'm starting to look thru RPi Zero W forums as well for WiFi issues similar to mine.

Thanks, @robolink_leila!
Is it possible to SSH into Zumi in this state (dashboard not working)?

RE: Loading....posted in Zumi
@robolink_leila @robolink_wes any guidance, please, on how to proceed here?

RE: Loading....posted in Zumi
@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
.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?
