Did any of you have problems using the random function of the LR1110 to create devnonces for Lorawan 1.0.3 versions? It seems to not be a real randomness source, as the numbers i get from the function repeat themselves pretty often.
This behaviour is pretty critical, as it breaks the joining procedure after a bunch of tries (devNonces are then always the same and the network server thinks it is a reply attack, which is actually how it should react).
