Am first-time working thru wiki.02 (Direction Finding Quick Start) and stalled at the section ’ Start and Control the KrakenSDR’. My Pi IP is 192.168.43.27, apparently a generic IP. Nothing happens. What am I doing wrong?
Are you trying to access the GUI being served by the Pi?
That is how I read the instructions. Am I mistaken?
You should add the port number to the IP address, :8080
My Samsung Galaxy phone shows ‘krakensdr’ as a Connected Device, but has no ‘Details’ button or other obvious method of adding :8080 to the RaspberryPi IP address. What am I missing?
Opened a tab on my Windows 11 laptop and entered the full IP address (with :8080) and got ‘can’t reach this page - took too long to respond’
Refreshed multiple times, same message.
Suggestions?
Do you have a monitor connected to the Pi?
From your laptop, are you able to ping the Pi?
I connected my laptop to the Pi with a HDMI cable, opened a tab and typed ‘ping. 192.168.43.27’ Bing offered me ‘ipshu.com’ with a login by user name and password choice. Am I getting closer?
Are you able to connect a monitor, or SSH in, and try running the troubleshooting steps on the Wiki? https://github.com/krakenrf/krakensdr_docs/wiki/07.-KrakenSDR-Troubleshooting
I may have asked the wrong question. I set up my Samsung Galaxy phone as a mobile hotspot and opened the previously downloaded KrakenSDR app. I get the world map centered in Accra, Ghana, and can swipe and zoom to my home in Gold Hill, Oregon, but don’t know how to mark it or have the app open to it. The 7 symbols down the right margin don’t appear to do anything. How do I get past this point?
I opened the app and under Settings - Connection typed my Pi address, 192.168.43.27
Then, under KrakenSDR Server Setting, got “The webpage at http://192.168.43.27:8080/
could not be loaded because:
net::ERR_ADDRESS_UNREACHABLE”
Now what?
Is your Kraken connecting to the mobile hotspot? Can you see it in the Android settings as connected?
If it is connected, but you still can’t open the webpage, then something has gone wrong with the startup of the Kraken.
If possible please go through the troubleshooting guide to make sure that the Kraken has sufficient power and the cables are working correctly https://github.com/krakenrf/krakensdr_docs/wiki/07.-KrakenSDR-Troubleshooting

Under android settings, ‘Allowed Devices’, I have KrakenAndroid, password KrakenAndroid.
Mobile Hotspot is ‘On’, Wi-Fi Sharing is ‘On’, but ‘Connected Devices’ shows ‘No devices’.
Will look at the troubleshooting tips now, and thank you.
If connected devices shows nothing, then the first stage, which is to connect the Raspberry Pi to the Android device, (which has nothing to do with the Kraken code) has gone wrong.
When you started, did you have the mobile hotspot ON, before you turned on the Pi? When the Pi boots it should see the KrakenAndroid hotspot from the phone, and connect to it. If it’s not connecting, then there is a core problem. Maybe the OS is not booting at all, and maybe the Pi or SDCard is bad? Can you confirm with a monitor connected that the Raspbian OS is actually booting?
Mobile hotspot was ‘On’ before powering up the Pi. I don’t know how to implement your monitor suggestion.

When I connected my laptop to the Pi by HDMI cable and pinged the Pi as instructed by Windows Copilot, I got ‘4 packets sent, 4 received, 0 lost’.
I had removed the Raspberian SD card the Pi came with, and substituted a card etched with the October 2024 edition software described in the wiki Quickstart Guide.
Still ‘No connected devices’. What should I try next?
When you pinged, do you mean that you pinged from the Pi 4? Or from a networked device? If you’re pinging the Pi from the Pi itself, it will definitely work, as it’s just pinging itself. You need to ping from a networked device, and that will check if your network is blocking the connection for some reason.
For the mobile hotspot, can you double check that you have the correct hotspot name and password set up? “KrakenAndroid / KrakenAndroid” ?
