Hi, all. I have been going through the mesh examples and have been able to do the light switching, dimming etc examples and have used the RTT as well as physical buttons to manipulate the servers and clients. I need to know how i can set up the mesh in such a way that i can send an arbitrary data packet (advert?) from one node to the other and have the other node resend it back to the origin. The aim is to have two or more nodes communicating by sending and receiving packets and then log the latency data.
