Broadcasting range

Is it possible to customize the beacon broadcasting range behond the predefined values? For example, between 15m and 30m?

Afraid it’s only the predefined values for now.

A broadcasting range of 7m means that a sphere is created around the beacon with a radius of 7m, correct?

Yep, just keep in mind it won’t be exact 7 meters—it’s more of an approximation, and is susceptible to external factors, i.e. sometimes can be a bit less, sometimes a bit more.
