@Heizelmann I'm not sure I understood your concern.
Initialization is finished here, right before the main loop is entered:
1512 MCO:BGN:INIT OK,TSP=0
Since your timeout is set to 1sec (which obviously is too short to fully establish the transport link) the node will enter the main loop() after the timeout. However, since the link is not established, only init messages are sent at that point (i.e. library init, signing preferences, presentation). Sensor data will not be sent until the node is registered.
