I have an older Electron and Photo that I recently pulled back out the drawer and started playing with again.
I can get them both connected to the internet. From the Build site I can select them and signal them (to make the onboard LED change colors).
However whenever I try to flash new code to them I get an unable to connect.
What other tools should I try? Looking at older posts they seem to be 1-2 years old so I wasn’t sure if they are still applicable.
