MESH Bluetooth PHY version

[Jakub Janusz]

Hello,

After having read the documentation of "nRF5 SDK v15" and "nRF5 SDK for Mesh v2.0.1" it is not clear to me which PHY layer it uses at the end.

In the documentation I found the following contradictions:

• On the one hand "nRF5 SDK v15" (and more specifically "S132 v6.0.0") support BLE 5.0.The documentation of "nRF5 SDK for Mesh v2.0.1" indicates that it requires "nRF5 SDK v15" (using "S132 v6.0.0" in my case) in order to be compiled and work. Which makes me think that you could use the PHY BLE 5.0 layer of "S132 v6.0.0"

• But at the same time in the documentation "nRF5 SDK for Mesh v2.0.1", it is indicated that Mesh uses the "Bluetooth Low Enery 4.0 PHY" layer
  
  • http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.meshsdk.v2.0.1%2Findex.html

So my question is, if we use the SDK mesh 2.0.1 + nRF5 SDK v15 (S132 v6.0.0), which PHY layer will be used by mesh? BLE 4.0 PHY or BLE 5.0 PHY ?

Hi Jakub,

As you can see in this link, the document says: "The Bluetooth Mesh is based on the Bluetooth low energy part of the Bluetooth 4.0 Specification and shares the lowest layers with this protocol."

Many people wrongly assume that Bluetooth Mesh uses Bluetooth 5.0, but this is not the case. 

Kind Regards,

Bjørn

Hello again,

Going back on the same topic, I would like to ask (if possible) if Nordic has plans to implement the BLE 5.0 physical layer in Mesh? either in short or long term?

My best regards,

Jakub
