Proxy feature in bluetooth mesh network

[letuan]

If i want to provision a device by mobile app over GATT, will this device support proxy feature to provision directly or provision undirectly over one proxy node

Hi Tuấn, 

Currently in Bluetooth specification there is no option to do provisioning remotely. So if you want to provision a node by the phone, the node need to support PB-GATT (provisioning bearer via GATT). This means it must support GATT connection from the phone directly. 
The configuration phase can be done undirectly (because it's like normal mesh activity, not PB-GATT) but the provisioning need to be done directly. 

Nordic provides Remote provisioning solution, but it doesn't cover provisioning from a phone. And it's proprietary protocol by Nordic.
