If you haven't set machine's Wi-Fi settings or connect it to any network, you will not be able to connect to the FLUX Delta. The micro-usb cable is just for name, password & wifi settings. In older version of FLUX Studio, this error is rendered as FLUX Device not detected.
Or.. just an network issue. Check Wi-Fi indicator ( green light ) of the FLUX Delta first, and connect your computer to same network. If you are Windows users, this might be a firewall issue ( note: do not turn off firewall ).
[ If the green light is blinking ]
It means FLUX Delta is still trying to connect the Wi-Fi, this could be caused by weak signal or wrong password. Shorten the distance between FLUX Delta and router might help.
[ If the green light is steady on ]
It means FLUX is successfully connected to your Wi-Fi, so you don't have to set machine's Wi-Fi anymore now.
Windows Users ( Green light steady )
If you set the wifi with micro-usb & FLUX Studio v0.3.0+
And still get this error - Make sure your firewall is running, reconnect wifi with your pc and restart FLUX Studio to see if it works. If not, there might be software conflicts like 3rd-party firewall or antivirus software.
If you set the wifi with USB Drive
And still get this error - Kindly find the IP Address of your FLUX Delta, the ip address displays in the DHCP Table in your router's control panel, and see if there is a raspberrypi device. To find where the DHCP table is, kindly google "DHCP table + Your router's model name". If you entered the IP and still nothing shows up, make sure your firewall is running, reconnect wifi with your pc and restart FLUX Studio to see if it works. If not, there might be software conflicts like 3rd-party firewall or antivirus software.
If your computer recently went to sleep
Note: When your computer wakes up from sleep mode and this error popped out, use command line to run "ipconfig /release & ipconfig /renew". In FLUX Studio v0.3.0+, you can enter the IP in Menu > File > Preferences in order to prevent this issue.
