Mesh like network base on BLE connection， BLE and long range conexist issue.

Question

Hi, All 
 
 In our product development, we finally found that our products need to work in long range mode to improve the communication range, and keep the connection with mobile phone at the same time. so my first question is, is it possible to make the BLE 1M conexist with long range mode? Is there any example and related document for me? 
 
 We connect our products with each other by a start network base on BLE connection: 
 but we have more intresting in the MESH like network which was showed in webinar video " introduction-to-blue-low-6-1-video': , and is there any example and document for reference? 
 
 Thank you very much!

Hi, 
 The term "Low Power Node" (LPN) is for nodes that communicate using the normal ADV bearer for communication, but has a "Friend node" in the network that will store all messages addressed for the node. The LPN can then wake at certain intervals, and poll the Friend node for new messages. 
 If you use the GATT bearer, it will not be a "Low Power Node" in Bluetooth mesh terminology, but it will look similar to your illustration, yes. Except what you marked as "LPN" will be GATT client nodes, and what you marked as "Mesh relay" will be nodes with the GATT proxy feature enabled ("GATT proxy nodes"). 
 GATT proxy nodes can connect to multiple GATT client nodes yes. 
 For getting familiar with the possibilities in Bluetooth mesh, I recommend having a look at the Bluetooth Mesh concepts section of our nRF5 SDK for Mesh documentation.
