You should not mix addressable and non-addressable nodes and NXP decided recently in 3feaa4342637eef673243dd38ccb32e8dc8efd5a that everything will be non-addressable. Writing bindings ask explicitly to post bindings, so if you decide to do half-baked solutions it's on you. Half baked solutions are not allowing to bypass standard rules. Best regards, Krzysztof
