From this post I understand that the mesh stack currently only supports EFR32xG12/13 devices. I am new to the SI lab ecosystem, as far as I have been able to tell EFR32xG12/13 are only available as SoCs or dev boards is this correct? From the mesh modules page it seems that these modules are compatible but from this post it looks like they are not yet supported, are any of the commercial modules supported in the stack yet?
The MGM12P is based on the EFR32MG12 so that supports the current BT Mesh SDK beta release. Support for EFR32BG1 will come later on.
Thanks for clearing this up!
