Dear community, 

   

we are working on a product which would greatly benefit from Bluetooth Mesh Networks. Multiple devices would all be connected to one phone. The devices should be able to repeatedly blink a light at exactly the same time. 

   

With the new Bluetooth 5 spec adopted yesterday, and Cypress having a Mesh Network solution already for Bluetooth 4.2 compatible chips, I hope I can find an answer to this interesting question:

   

Using mesh networks, do you think a very accurate synchronization of all the devices in the network is conceivable?
Would it be possible to compensate for all the individual delays that occur between the devices?

        Hello Cypress is currently working on Bluetooth Mesh solution with our CYW2xxxx parts and will have solution available in early 2017. This would comply with Bluetooth 5 spec.

I got that information from Cypress as well. But do you think it would be easy to design a system that executes actions in synchronization? We're looking for millisecond accuracy, microsecond accuracy isn't needed.

If you designed a system that used the built-in RTC on the module, timed/compensated for individual packet transmission times, and then synchronized all of the devices to a central "time keeper", then yes it would be possible. But it all depends on the implementation.

Welcome!

Has Cypress release the Bluetooth mesh products yet? I am very interested in using them.
