USB A type Bluz Gateway is no longer able to connect Particle cloud anymore.
It was acting strangely such as disconnecting from WiFi occasionally.
Now that I plugged into wall outlet. It was fine for a while. After that, it is flashing blue and I thought the wifi memory resets or something.. then I used Particle CLI to reconfigure the wifi to Bluz Gateway..
After entering wifi ssid and password, it is trying to connect to WiFi by flashing cyan.. unfortunately the fast blinking cyan is being followed by short pulse of red rgb..
I have uploaded video to Youtube which shows the RGB sequenece of Gateway.
Sometimes it shows this error.
