There is a solution for BLE mesh on FRDM-KW41Z, but unfortunately it is not public anymore. I don't know when will be publicly released again.
thanks for this information. Could you maybe find out, if there are plans at NXP to implement the BLE mesh functionality to the MKW41Z chip again? Thanks a lot!
Let me get to you next week, the guy that worked on BLE mesh is in vacation and will be returning sometime during the following week. If I don't come to you until next Wednesday, mention me here (with @).
