Set radio range of node in ble mesh.

[Pooja]

I want to test the mesh network for that i have to set the radio range of node to minimum distance so that i'll able to test the relay node example. Will you please help me to set the minimum radio range for node programmatically or is it possible to set the radio range?

I do not believe you can specify a range for the radio. However, you can control the transmit power of the radio and therefore have some control over the range of the radio transmissions. Take a look at sd_ble_gap_tx_power_set in the file ble_gap.h.

It is possible for to enable the radio when required instead of keep radio enabled all the time?

Sounds like you want the Sleepy node with friend support for the mesh network. As of a few months ago this wasn't supported. Take a look at this: https://devzone.nordicsemi.com/f/nordic-q-a/28486/low-power-node-support-in-nordic-ble-mesh

Hi,

I can confirm that we do not yet have friendship in the current nRF5 SDK for Mesh (v1.0.1), although it is definitely a feature we will support in the future.

Thanks for your response

Mesh SDK 1.1 wll have support for the Mesh Proxy which will also support low power operation. Why did you want to "enable the radio when required", is this for low power operation or is it for something else ?

i only need for testing purpose, beacuse while testing relay node there is need to place the device far from each other. From where i can download the mesh sdk 1.1
