Ble 5 mesh

[Robbylaw]

hello I am just needing some clarification on meshing. I am using the long range nfr52 chip. I have a transmitter with a tilt switch that connects to my receiver when connected the receiver has a light that blinks. I am getting 75 feet indoors. My question is with meshing can I add another receiver say 50 feet further making it 125 feet and use the other receiver to make the longer range connection and then add another further and so on say maybe up to 250 feet ? Does each receiver have to be programmed? And will one receiver at the end of the line need to be an end node ?

You mean the nRF52840 - using the Coded PHY?

I think using Coded PHY is not actually compliant with the BT SIG specification of BLE Mesh?

Yes, that is one of the main points of Mesh.

Yes.

And the Mesh needs to be provisioned.

Hi.

Thank you awneil for your response!

I would just like to add:
Altough the BT SIG spec. for Mesh is is based on the BT SIG v.4.2 spec. and doesn't include any BT5 features, it' still possible to test Coded PHY (Long range).
