P2P between mobile devices

I am evaluating proximity SDKs: so far newaer, p2pkit, hypesdk, underdark
I’ve just come across Estimote, so I want to check whether it makes sense in my scenario.

Basic requirements are:

  • find me nearby users that use the app (with proximity SDK)
  • send / receive p2p message to the discovered device

Is this something that Estimote SDK can be used for?
If so, are there any examples?

Thank you,

Hello, anybody?
