Hi my spark 3 led status is flashing green very quickly with an occasional white light. Is that normal?
Flashing green means it’s looking for Wifi.
Thanks Bob is there an easy way for me to disable it as i don’t use wireless keep it cabled
I’m afraid not. If it’s in range of a Wifi network, you may as well connect it. Cabled devices always get priority during discovery anyway.
You can clear the WiFi credentials as described here:
However, after a firmware update that has a system layer or bootloader the Spark will download these from the Particle cloud, which requires WiFi.
They can be flashed over USB to, but with WiFi it is a bit more cable of fixing itself.
Thanks both great service as per usual
