Is there a document that specifies a range of ID's available for custom models ?
Or is it completely arbitrary?
Thanks
Hi,
Vendor model IDs are 32 bit values consisted from a company identifier and vendor-assigned model identifier. See section 3.7.2 of MeshPRFv1.0.1. It is up to a vendor how to organize their model IDs. E.g., for Nordic we have a list of assigned model IDs here: http://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/ug_bt_mesh_reserved_ids.html
Same for messages opcodes (section 3.7.3.1 of the spec).
