Good morning,
I have read the documentation that you provided and the datasheet of the new module. The RAM/ROM amount of the new module (128KB RAM/128KB ROM) should be enough to implement the new commands or reroute existing ones to implement the required behavior. From my point of view a week would be enough to get to know the Jennic SDK, implement and test the commands.
We could do a test project so that you can decide if I'm the right one for the project!
