Hi askubel - I think we need to see more details of Thread before we can say things like this. CSRmesh does support over 250 devices in a single mesh - that has been demonstrated, along with the lower power capability for LED lighting, so it does address exactly the points you rightly raise. I'm not sure you can say the same about Thread as yet - once it is opened up, then we will have the chance to see how the implementation differs, particularly with the need for a hub to link to a smartphone.
Until then, there is still this pretty fundamental split on which protocol and underlying technology to choose.
As IoT grows out of its infancy, there will be room for improved standards -- especially those that offer lower power consumption. Just because BT Smart is the incumbent, don't assume that challengers can't improve on it.
Those are good points askubel, and that's exactly why CSR developed the CSRmesh, but with a lighter protocol that does support thousands of devices - it looks like the engineers at CSR and Nest were looking at similar solutions from different directions at the same time, which is why we end up in this kind of situation.
It will be interesting to see CSRmesh opened up as the company has said, but Thread also needs to be an open protocol.
Then I suspect there's an opportunity for smart ways to provide a multi-protocol solution without the resource overhead - that's the kind of thinking that Imagination Technologies is following with its auto-discovery and configuration approach.
These responses are missing the point. Yes, BT Smart has IPv6. Yes, it's low power. Yes, you can make a mesh network with it.
Do they really think the engineers at Nest didn't think about that? Creating a new standard is a massive job that will face a lot of resistance. They didn't just make Thread up for fun or to have a proprietary ecosystem to lock out competitors.
I don't know exactly why BT smart wasn't good enough. What I suspect, is that while it is possible to build a mesh network with Bluetooth it isn't possible to do so with the extremely minimal power consumption promised by Thread, and I also suspect it isn't possible to build an efficient BT Smart mesh network that can scale to over 250 devices.
