This patch allows the application to modify the CID, PID, VID and CRPL in the composition data. According the Mesh Profile (2.3.4 Elements) the modification of fields other than "Elements" is not prohibited. Also in my opinion (as you can see in the 1st patch), there is no need to use pointer to the node_composition struct. The static is more clear and less problematic. Jakub Witowski (3): mesh: use static node_comp instead of the pointer mesh: add composition data setter mesh: allow to reattach with new composition data mesh/mesh-config-json.c | 46 +++++++++++++++----- mesh/mesh-config.h | 2 + mesh/node.c | 96 +++++++++++++++++++++++++---------------- 3 files changed, 96 insertions(+), 48 deletions(-) -- 2.20.1
