BLE mesh and Routing for high frequency Bridge sensors

[Steve]

I recently got involved in a project where I am deploying a ble based mesh to understand and monitor bridge vibration patterns. I have been through nRF's mesh capabilities, but they aren't enough high frequency and efficient for my particular use case.

I was wondering if I can control the routing protocols mentioned in a similar way this BLE mesh routing for IoT post. The listed possibilities of controlling routing is something that interests me a lot, as a structural engineering initiative I want to propose my organization to focus more on how moving vehicles on top of bridge impacts the overall patterns of vibrations. We are trying to sync the routing in a way that synonymizes the pattern of moving vehicles, minimizing energy and the number of nodes required as well.

I am not sure if that's really possible. But, I want to try it out. Has anyone been able to do anything like this?

Hi Steve,

The BLEmesh mentioned in the post is not the same as Bluetooth Mesh adopted by Bluetooth Sig.

The proposed routing mechanism is proprietary. There isn't much data on the worst case latency the mechanism can create. Have you tried to contact the author ?

If you want to develop your own mesh, I would suggest you to have a look at open mesh implementation we have. It used trickle algorithm instead of TTL floodmesh as in Bluetooth Mesh. It might be a good candidate to be modified to add the BLE mesh algorithm proposed in the post.
