Hello,

I am interested to learn more about the platform. Does anyone would like to share what he`ve done with the platform?

How is it to develop for example 5 temperature humidity sensor communicating to a platform like raspberry pi over bluetooth mesh network?

Thanks

The CSRmesh implementation is a bit tricky with respect to reliability and power consumption, but with some experience you can make it work very nicely. Reliability is due to the fact that stack overrun crashes the CSR stack and the debugger does not recognize that. We have built several products using the CSRmesh you find on our aircable.co web site.

The most remarkeable product is the serial-to-mesh implementation. Basically we take the UART data and publish the data to the mesh. Other devices can then pick them up without making a connection. All they need to know, who is the publisher. With this solution you can implement a 1:1 as well as a 1:many type connection. Even more we did a many to 1 type of connection or a mode, which lets all serial-to-mesh devices print every message from all other serial-to-mesh devices. 

Our new version is now able to adjust the CSRmesh power consumption dynamically on the node to implement an energy harvesting algorithm that gets the power from the RS232 TX line. This leads to products that were not possible without the CSRmesh. It does not require any power or battery.

You also find a light switch, generic sensor node, sniffer, bridges and gateways as well as open source implementation of the CSRmesh on Github.
