Sir I am also having the same problem. And the video link : https://youtu.be/yOCj41xDBN4 has been removed. Please give an alternative method.
I have installed BOLT app and tried adding my BOLT IOT device to it but every time it states "Please ensure that the device is properly connected to the USB". And also I downloaded the NETPLUG and tried configuring there too but failed. Moreover, my laptop connects with BOLT IOT kit wifi only sometimes and if connected the connection shows limited and I can't open the setting page by entering the bolt_ip_address/settings in my browser.
