AWS IoT Core integration - setting brand, model and/or payload formatter

We create our things in IoT Core and they are synched with TTN. But we want to have control over the payload formatters. To use the formatters from device repository we must be able to set the brand, model, and version attributes. Can we create attributes in IoT Core that are synched to TTN? Or alternatively is ther a way to set the payload formatter (javascipt) somehow?

Go to your device, select “Payload formatters”, then select “Custom Javascript Formatter” in the dropdown.

Thanks, but it doesn’t answer the question. We know how to update the payload formatters in the TTN console. We want to know how we can update them from AWS IoT Core, because we manage our devices in AWS IoT Core.

Sorry, I din’t catch your point. Thanks for clarifying.
