I am currently working on an application where the node has almost no up link data but a lot of down link data. The node has to send multiple empty packages to open the receive windows for all this data. This takes a lot of power.
I thought of a possibility to open the connection as a class A. The node sends a request for data and the connection switches to class C until all the data is received. After the last data the node switches back to class A and goes back in deep sleep.
Is this method possible or is it necessary to have a predefined class?
