There are a few situations when it might seem that the Prota is broken or has a defect.
Make sure to use a 5V 2A power supply. Unstable power supply can make the device randomly fail at any point. Do not use PCs or laptops as a power source.
Try rebooting, just unplug and plug back in to a power source. If that doesn't work, try resetting.
If none of these steps work, please contact us directly at firstname.lastname@example.org and we will investigate the situation.
