I have two PizelBlaze setups working since last November, and now I want to change the pattern but Discovery isn’t working anymore and when I ask the router to list all the devices it shows their MAC addresses but says they are off and gives no IP addresses, so I can’t run the control software on my Mac or iPhone. I’m stuck, and don’t know what I’ve done other than update my computer.
The only suggestion I see is to reinstall the WiFi, but how do I do that when the system is running OK??
For wifi issues, the first step is to reset the wifi. Solves my problems 90% of the time.
When the PB is on, do a long press (5 sec) on the Pixelblaze button. You will see the light indicator blink shortly, and the PB will restart in AP mode, allowing you to reconfigure the wifi.
