PAN1760A will be released in the next couple of weeks. Indeed it will allow the user to utilize MESH 1.0.
As a matter of fact, the PAN1760A is the leader in its class for low power consumption, hence the best offer solution for MESH.
The SDK for the MESH will be released in the next few months. Please note that the greatest challenge for testing the MESH is other products in the market that support MESH 1.0... with out enough products it is impossible to go through enough interoperability testing
