Changing periodic time for ticker

Getting Help
1

I am working on project where I periodically query devices. If I want to change the frequency ( or time)
How do I do it.

I plan to scan the devices and get timer and create ticker and pass function pointer to it. If I want to change time ticker time how can I do it. Is there anyway to update ticker time.

You will have to show us at least some code that you use now. Without code, it is impossible to know you do periodicall querying and how you created a timer.
