Mesh Network based on BLE4.0

[Hongtao]

Hi All,

I noticed CSR has just released something called CSR mesh, please see: http://www.csr.com/news/pr/2014/csr-mesh, and a demo video: http://www.youtube.com/watch?v=FtLBazKoFq8&feature=youtu.be, It is very attractive, and it was said based on BLE4.0, Does anyone have any ideas on how it is implemented? will Nordic chip do this?

Thanks.

Is the idea of the nRF51422 with the S310 not to do exactly this?

Use BLE to have a phone connect to the network.

Use ANT for a mesh.

Or am I wrong?

While ANT allows mesh networks it isn't the main use case for ANT in my experience. I believe most ANT applications use star topologies only.

That said, I agree the S310 ANT/BLE stack should be a possible option to implement something similar to the CSR demo. Rather than using advertising and scanning in BLE you could set up broadcasting channels using ANT. A big advantage of this approach is that the S310 stack is available today, while we don't currently support combined advertisers/observers.
