May I know how to access my training videos and what does it mean by product not linked?
To access the training content you will have to create an account on cloud.boltiot.com
Then later you will have to visit cloud.boltiot.com/training and read the steps given on website and follow them.
Linking the Product means it will transfer the configuration over the internet to your Bolt Wifi module or the device to which you want to transfer your code to. So if you do not link your configurations to the device then it is said to be " product not linked " . To link your product click the link product option to the right top corner on bolt cloud.
