Changing send period through AWS

Application Development AWS
1

Hi

I would like to change the send period of my sensor through Amazon Web Services.

This is the setup:
AWS Lambda -> AWS IoT Core -> The Things Industries -> gateway -> sensor

For example, this is a hex string that changes the send period of my sensor (Elsys ELT-2) to 60 seconds: ‘3E06140000003CFE’

How can I send this hex string as downlink messages to my sensor using the shadow document in AWS IoT Core?

I have read up on shadow states (https://www.thethingsnetwork.org/docs/applications/aws/thing-shadows.html), but this information seems to apply to payload that is send by the sensor.

Thanks in advance
