Hi,

For most samples the relay feature is turned on by default.You can check the CONFIG_BT_MESH_RELAY kconfig setting to see if relay feature is enabled for the sample. If you then position the devices such that e.g. device 1 and device 3 both are in radio range of device 2, but not in radio range of each other, you can check to see if relay works on device 2 by controlling device 3 from 1 (or vice versa.) Please make sure that the publish settings from the sender node has a TTL of at least 2, in order for the messages to be relayed.

Regards,
Terje

THANK YOU TERJE FOR YOUR KIND INFORMATION .

I WANT TO RUN MY NODES -1 , 2 , 3 AS THE RELAY NODES AND CONNECT IT IN A NRF MESH APPLICATION .

AS YOU MENTIONED I CHECKED THE ABOVE DOCUMENTATION YOU PROVIDE , I AIN'T FIND THE TESTING OF THE RELAY NODE .

HOPE FOR YOUR VALUABLE INFORMATION .

REGARDS,

MOHSEEN AHAMAD.

Hi,

From what I understand, "nrf mesh apk" in your diagram is a smartphone using GATT for connecting to the Bluetooth Mesh network. Such a device cannot funciton as relay node; it can only connect to one GATT Proxy device of the network.

When you provision multiple devices into the Bluetooth Mesh network, packets will get relayed automatically through relay nodes. All you need is to do initial configuration of the devices, where the sender and receiver of messages use the same application key, and publish /subscription addresses match.

For details on each SDK sample, please see the documentation for each Bluetooth Mesh sample in the SDK, where the testing section describes configuration and usage.
