Trouble Flashing Devices

Troubleshooting
1

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.

The Swiss Army Knife for Partice devices is CLI

Of all the commands in there
https://docs.particle.io/reference/cli

You’ll most likely want to use these to address your issue from above

particle update
particle flash --usb tinker
particle flash --usb <yourOwnProject.bin>

But you could also try Safe Mode first when OTA flashing fails due to your own running code interfering with the update.
