A simple mesh on the NRF52 DK (maybe using light) switch example?

Hi There, I'm very new to mesh and have a bit of a learning curve to understand the mesh SDK. A few questions for those in the know....

I have been playing around with the light_switch demo and have it working (understanding it is more difficult). I have been trying to make it work in reverse. Basically I would like the servers to send their state to the client instead of the other way around. Rather than setting an LED on the client (although it would be useful initially), I would like to send a something via REST API to the outside world.

The terminology used in the light_switch demo is server and client. I assume "server = node" and "client = gateway", is this correct?

I have 5 x nRF52 (PCA10040) dev kits and am compiling using Segger Studio.

Essentially, I would like an easy demo of a mesh sensor network that uses a simple GPIO pin to detect on/off for the sensors, then send this data to a gateway and the outside world.

Anything you can do to help would be really appreciated.

Another way of putting this is, I would like to send a message from the server to the client (a bit in the client has been set or a button on the client has been pressed). I then want the client to send this information to a website.

Hi,

It is great that you have the Bluetooth Mesh example up and running. I recommend that you read some of the available documentation to learn how the pieces fit together.

• Basic Bluetooth Mesh Concepts
• The nRF5 SDK for Mesh architecture
• How to build a network
• Introducing Bluetooth Mesh Networking by Bluetooth SIG

We do not have a ready-made gateway for Bluetooth Mesh. You will have to make your own. We provide the serial interface as a starting point, though. You may also want to take a look at the Serial example.

For the GPIO functionality you could have several nodes running the Simple OnOff model.
