BLE MESH: First time developing with BLE (MESH) and microcontrollers

[Kapteni]

Hello everyone,

We are 4 students, who are developing a BLE mesh network to send data from a CANNBUS-simulator to a desktop. We have chosen to use the nrf52840 chip to set up the BLE mesh network. We ordered two Development kits and have been reading through the online documentation provided by nordic and looking into the provided examples for mesh networking, more specifically the lightswithc example for two weeks now.

So far, we've had a hard time understanding how to build our own model or adapt an existing model for our purpose.

Are there any guidelines or other sources about how to develop applications and get to know mesh networking with nordic chips? Maybe other simular projects/tutorials/...

We've some experience programming in C and know the theoretics of BLE (MESH) but we don't have any practial experience developing BLE MESH applications

Thank you in advance!

Hi Kapteni, 

We provided a vendor specific model in \Mesh_v4.0.0\models\vendor . You can find the simple_on_off model and the rssi model there. They are the good getting started place for you. We unfortunately don't have an example that use these model in SDK v4.0

To understand how things work, I think it worth to have a look at older SDK version, for example v2.1.0 here: https://github.com/NordicSemiconductor/nRF5-SDK-for-Mesh/tree/a2e3eabd74dd645d183381967ec617a06ab94da8

In this version we use the simple_on_off for the light switch example, and maybe it's easier to understand the code there. After that you can get back to SDK v4.0 and implement your own vendor specific model.
