No you don't see that, but yes, that depends on what program is selected on the mobile phone.
So, in another 'program', C (lower right) should be able to talk to B (upper right), kind of a reverse
order. you said i'ts not a correct diagram for point-to-point (obvious), but also not for point-to-multipoint.
That leaves only a mesh topology right? or am i missing options?
Thanks!
