Just a short guide 🙂 I did this in windows 10.
step 1 ) first update firmware! Format an usb to be either FAT32(win) or EXT4(linux) and download the latest firmware. Put it onto the usb, as the only file there.
step 2 ) put the usb in the second usb port and wait 5-10 minutes
step 3 ) if the LED has begun to slowly blink, you are done. Press the button on the back to go into "Arming mode"
step 4 ) in "Arming Mode" we can connect to the Signal owl, check your wifi and owl_xxxx(last 4 mac address, should be in the network)
