This morning I tried to connect my LIG16 to TTS Basic Station using the beta firmware. I could connect without problems, data-packages were transferred from my gateway to TTS. I could see all my nodes in their applications.
But then I observed that the system-log of my gateway filled up with “Time sync rejected”-messages.

Additionally nothing was shown anymore in LogRead/ Gateway Traffic of the LIG16.
I stopped the experiment and went back to Semtech UDP.
