How many Mesh Nodes does DA14586 support ?
The mesh for the 585/586 is not yet released and is still under development and not evaluated yet in order to provide that info. The amount of nodes supported is resource and memory footprint of the code dependant, so we dont have this information yet.
When can we expect the Bluetooth mesh stack for DA14585/DA14586 development boards?
Presently we are working on DA14585 DB+ Pro MB. If support available early we have to procure more development boards of DA14585/DA14586 for checking mesh network.
Sorry, still i dont have an available date to mention on releasing the mesh on the 585/586 family. The project for the mesh is still under development.
