a couple of questions about the mesh pb_remote mesh example

[Rcmesh]

Hello,

I am using the mesh pb_remote example in order to have a multihop scenario. I would like to do some latency calculations, so some kind of bidirectional communication would be usfeul to me. But I have the following question:

Is the communication completely unidirectional (from the client to the first server and from the server to the next server)? Or do the servers repond back with some kind of acknowledgement? As I have seen by sniffing the packets, it seems to be the first situation. In any case, is there some other example that has bidirectional communication between devices?

I take this opportunity to ask another unrelated question: Is there some way to disable security? The sniffer receives what is shown in the image, and I would like to see the decrypted data.

The devices I use are the nRF51422 (PCA10028 and PCA10031).

Thank you very much!

If you want "bi-directional" communication, you can use the SET (or GET functions), see Simple on/off model in the documentation.

For sniffing mesh packets, the nRF Sniffer v. 2.0 has to be used.

Note: I would recommend you to switch to nRF52 instead of using nRF51, because the from nRF5 SDK for Mesh v.2.0.0, support for nRF51 is deprecated.

Thanks for the response, I will take a look at the Simple on/off model. 

Regarding the packet sniffing, I already use nrF Sniffer v. 2.0 (with Wireshark). My question was more oriented towards if it is possible at all to "disable" data encryption, because I see the sniffed packets have the data encrypted and I would like to see their content.

Thank you again!
