Support of Extended advertising within BLE mesh stack in nrf connectsdk

[Ashishsult]

In the latest release v1.8.0, there is an example ( Mesh and peripheral coexistence) which also has the extended advertising.

However, it seems that the BLE Mesh stack and extended advertising are separated. Is there any plan to add support of extended advertising to the BLE mesh stack in near future?

It can really help to send large payload over the Mesh network.

Hi,

Bluetooth mesh is built on top of Bluetooth 4. Features from Bluetooth 5 are not part of the mesh stack. This is by specification, as published from Bluetooth SIG.

We did have a proprietary solution in nRF5 SDK for Mesh using extended advertiements, for higher throughput, named Nordic Advertiser Extensions (Instaburst). I am not aware of any current plans for implementing the same in nRF Connect SDK.

For our future plans and roadmaps, please contact our sales representative for your area. If you do not know who that is, please ask in a private case or private message and we will provide the contact details.

Future plans and/or drafts for upcoming Bluetooth SIG specifications may be available to SIG members of the proper membership level.

Regards,
Terje

Thank Terje for the answer, I would like to explore the Instaburst feature. Do we have any available example explaining how to use this feature to send and receive packets?

Hi,

The Instaburst feature is available in nRF5 SDK for Mesh. In order to enable Instaburst in the stack, you need to build the stack with CMake after enabling the EXPERIMENTAL_INSTABURST_ENABLED option in the CMake configuration. There is no dedicated example, but all examples will use Instaburst after the stack is built that way. See the "Usage in Bluetooth mesh" section of the Nordic Advertising Extensions (Instaburst) documentation page.

Please note that nRF5 SDK (and thereby nRF5 SDK for Mesh) is in maintenance mode. It means support for new features will not be added to that SDK. Moving forward, nRF Connect SDK is the recommended and supported SDK. See our nRF Connect SDK and nRF5 SDK statement for details.
