As well as USB-C, the EasyFlash connects over Bluetooth LE and 2.4 GHz Wi-Fi.
Each EasyFlash goes by EasyFlash and a four-character code, such as EasyFlash 4F2A, over both Bluetooth and Wi-Fi. The code is made of digits and capital letters, but never I, L, O or U, so it can't be misread. The label on the EasyFlash shows its name and its Wi-Fi password.
You can give the EasyFlash another name, and change its Wi-Fi password. Changes take effect the next time it starts, such as when you unplug it and plug it back in. Its code never changes, so you can always find it by its code.
The first time a computer or phone connects to the EasyFlash over Bluetooth, the two have to pair, and you approve the pairing with the EasyFlash's button:
You can also press the button first. For the next minute the blue light flashes quickly, and the next pairing is approved without waiting.
Once paired, a computer or phone reconnects without asking again. The EasyFlash remembers the last eight it paired with. Pairing a ninth forgets the one paired longest ago.
Before you connect, the EasyFlash tells nearby computers and phones whether it has been paired, whether it's on a vehicle's power, whether it's waiting to pair, and whether it's running a job. That helps tell one EasyFlash from another.
Out of the box, the EasyFlash runs its own Wi-Fi network, with the same name as the EasyFlash. To connect to it, join the network named after it, such as EasyFlash 4F2A, with the Wi-Fi password on its label. The EasyFlash is at 192.168.2.1 on its own network.
You can set the EasyFlash to join your Wi-Fi network instead, with the network's name and password. It only joins 2.4 GHz networks.
From its next start, the EasyFlash joins your network, and computers and phones on the network find it by name. If it can't join within 30 seconds of starting, or of losing the network, it also runs its own network and keeps trying to join yours. So you can always reach it on its own network.
Anyone who knows the EasyFlash's Wi-Fi password can connect to it over Wi-Fi. If other people can see its label, change the password.
Over Wi-Fi, you can rename the EasyFlash but not change its Wi-Fi password or network. Do that over USB, or over Bluetooth from a paired computer or phone.
A network reset puts back the EasyFlash's original name and Wi-Fi password, sets it back to running its own network, and forgets every computer and phone paired with it. You can only reset it over USB or Bluetooth, and the reset takes effect the next time it starts.
