nRF52832 with dynamic mesh

[Lukic]

Hi Guys

I have a noob question about the mesh network for nRF52832. For devices to be inside a mesh network, does it mean that they need to do some kind of parring or can the introduction of new devices be done on the fly ?

Lets say we have 5 persons where each one of the have a chip in the pocket. When they pass by each other, is it possible to make a quick on the fly data transaction between those 2 devices, where we can share data that is saved inside the local memory.

I'm thinking of some kind of tracker. So if I make an app that is scanning for devices, and the device I find during the scan can then tell me what other devices it have been in contact with, and if those devices are still in reach of the mesh network.

As I can read on the Google, all devices need to be parred before mesh network can work. Is that true ?

Hi,

this mesh here: github.com/.../nRF51-ble-bcast-mesh does use advertising and will work on-the-fly quite good.

Other meshes, e.g. my FruityMesh github.com/.../fruitymesh will need to build connections between the nodes. It will try to self-heal, but that takes some time and is not a proper solution if multiple nodes are moving. Having a mesh and some moving nodes does however work in this model if they are implemented differently.

But for your use-case a broadcasting mesh is probably what you are looking for, so take a look at 1.
