@Ronan-Lacroix I have a question: The min value for T3412 is only valid for the “extended” version of TAU ? Does the 1 hour apply also to the min. value of standard TAU or is it shorter? Having a min TAU of 1 hour seems to me for many use cases difficult because the devices in those use cases need to wakeup from sleeping much more often (e.g. every 10 minutes). Many many thanks for your support! Regards, Roland I
