How to use bluetooth mesh exported json from mobile app with pyaci

Hi,

I would suggest you to start looking at Mesh in nRF Connect SDK.

There is no pyACI in nRF Connect. Instead there is a mesh shell that supports CDB to some extent. Details about this shell are provided here.
https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/reference/bluetooth/mesh/shell.html?highlight=mesh%20shell

This shell can be used with any serial terminal client such as putty. The configuration described in JSON will have to be manually entered into the CDB shell by using various available commands.

Hi,

Our mesh team said this is expected. Implementation in nRF5 Mesh SDK v5.0.0 is fairly old and does not support all features of the configuration database and only has limited support.

Moreover, Format of the configuration database has undergone some changes and the latest Android/iOS mesh apps have an updated implementation. The nRF5 Mesh SDK's implementation can be updated whenever there is a plan for the next release of this SDK, but I don't have the schedule.

Amanda

Hi Mital,

The format should be the same, so not sure what or why it is failing. Please elaborate in what way it is not working. What kind of data do you copy?

For an nRF5 SDK for Mesh application, you can use the Flash manager (for best compatibility with the mesh stack), although it should be possible to use fstorage / FDS from the nRF5 SDK as well (probably with some hit to performance.)

Amanda
