It is merely stipulated which communication partner receives periodically, ie scans, and which periodically indicates a willingness to communicate, ie acts as a so-called advertiser.
  • control of respective operating states of respective communication partners is therefore time-relevant. For example, after the display of a willingness to communicate within a certain time a feedback from the opposite side must be made, if they want to communicate. Furthermore, implementation-specific time constants within respective transceivers must be taken into account, for example switch-on or switch-over times.
