When Prota initializes itself, sometimes it might get stuck during the procedure. In this case, please reboot your Prota to make it work.
If it still doesn't work, please make sure you are using the correct power sourcing for Prota device.
You have to use a power adapter that supports 5V 2A voltage.
Please make sure you are not using the charging adapter of smartphone. Also, do not use PC and laptop for the power source.
If the problem persists, please contact Naran support team by submitting a ticket on support.prota.info.
