Example project for Mesh Instaburst

[grabro]

Hi,

We managed to integrate both normal BLE and mesh stack onto our working prototype, powered by nRF52840. So far, it is working well. We are trying to further maximise our developed node by experimenting mesh Instaburst feature, as our TX mesh packet is around 48 - 132 bytes.

Before we get a head start, just wondering if there is any example project/template we can refer to? With this, at least we know how to use this feature properly.

Many thanks!

Hi Siew, 
We currently don't have an example with Instabrust however as far as I know you don't need to change anything except for using compiling option: EXPERIMENTAL_INSTABURST_ENABLED  when you compile with cmake, as described here.
The use of Instabrust is executed under the hood and transparent to the application.

Hi Hung Bui,

Thanks Hung for your quick reply. But the link seems to not working anymore. Can you kindly recheck it?

Many thanks!

Thanks Hung Bui,

I will have a look and get back to you with my development status.

Thank you very much!

Have been trying to debug other bits and only managed to come back to this weeks ago. But getting nowhere.

I am keep getting this error message when trying to build with cMake. Tried using the cmake-gui and the command line tool and I got the same errors.

Any idea?

Hi Siew,

As you can find in the log, the SDK_ROOT is missing, you would need to call cmake with the -DSDK_ROOT something like this: 

cmake -GNinja -DSDK_ROOT=C:/NordicSDK/SDKv17/

The path is the path to the nRF5 SDK, not the mesh SDK. Please download the matching version of the nRF5 SDK to the Mesh SDK that you are using. 
Have you tried compiling with Segger Embedded Studio as well ?

Thanks Hung Bui,

I have tried to place both nRFSDK and mesh SDK in the same directory as suggested in the Getting Started guide. Here is the screenshot of the directory.

And I had tried to add the SDK_ROOT while running the cmake. But still getting the same error:

D:\NordicSDK\nRF5_SDK_for_mesh_4.2.0\build>cmake -GNinja -DSDK_ROOT=C:/NordicSDK/ ..

I am using:

• nRF5_SDK_16.0.0_98a08e2
• nRF5_SDK_for_mesh_4.2.0

As we have been developing the our mesh application since last year.

Also, when you mention whether I have tried to compile using SES, do you mean whether I have added the INSTABURST pre-compile definitives in the project setting?

Any suggestion will be much appreciated. Many thanks!
