Thanks Petter, we have requested for development boards online for our evaluatation. I am located at Mumbai, India. who would be the Regional Manager to connect. Please let me know.

In regards to when Bluetooth mesh will support nRF52840, I'm sorry, should contact the regional sales manager for your area regarding roadmap and future releases, if you don't know who it is send me a PM with your location and I'll let you know.

The gateway will be the bottleneck, and number of nodes in reach of each gateway is determined mainly by the traffic. I talked to one of the developers, and with a few of bytes every couple of second he thought 100 nodes per gateway would be in the right ballpark.

We don't really have a Cloud example, but the Serial Example can be used as a starting point, connecting it to a Raspberry Pi for example.

Thanks Petter, that was pretty good response, covers all aspects.

We definitely need more that 250 nodes, Thread has a a limitation, probably adding up more border routers may resolve connecting more nodes.

On Bluetooth Mesh When is the support for Bluetooth Mesh SDK for nrf52840 anticipated formally, I am assuming, we can still use it as it is compatible and works. Can u please let me know the recommended nodes supported on Bluetooth Mesh using nrf52840 and what could be the ideal Network System configuration considering number of Routers/Bluetooth 5 IoT gateways for connecting 7000 nodes? I need to send data from the 7000 nodes to out IoT Cloud platform. I am assuming that Bluetooth 5 Mesh network can achieve this. Or would you recommend Zigbee Mesh for this? Kindly clarify.

You should be able to use Bluetooth Mesh, but 6000 nodes is a lot. The theoretical limit is 32000 nodes, but how well the mesh will behave depends on the traffic. Your throughput requirements are not too high, but it will still be a lot of traffic with that many nodes.

At the moment the Bluetooth Mesh SDK does not support (but is compatible with) nRF52840 as you can see here.

Sounds like the Light control demo could be a good starting point for you. For that you need 4 kits, as you can see under hardware requirements, but it shouldnt' be to hard to modify the example to support more servers.

Currently, we do not have any mobile app example that works with either Bluetooth Mesh or Thread, sorry.

You might be able to use Thread as well, but then you have to split the nodes into different networks.

Each network can only have 32 routers, and then the rest of the nodes has to be end devices that are only connected to one router. A thread network is said to support up to 250 nodes in total.

If you want to use thread you have to use nrf52840, as you can see here.
