Hi Mandeep,

I wonder if there is a misunderstanding here. The Instaburst feature doesn't provide support for long messages. It changes the packet bearer from legacy BLE advertiser to a proprietary implementation somewhat based on existing BLE (not Mesh) features.

[quote user="Mandeep"]I have spent lot of work on my ble mesh application, with thousands of devices running in my project. Most of their based on long message support (Instaburst). Does this mean I cannot continue my project with NCS?[/quote]

But if you have thousands of deployed devices running Instaburst, then yes, that means that you cannot add more devices working in NCS.

[quote user="Mandeep"]If disregard the Bluetooth Mesh specification, is there a way to support long messages ?[/quote]

If you disregard the Bluetooth Mesh specification, then you can technically reimplement the Instaburst feature. I don't think it is going to be trivial and do not recommend this approach.

I see in the opening post you have this concern:

[quote user=""]SAR, and compared to Instaburst, is less stable or slower ?[/quote]

I haven't looked into speed comparison between SAR and Instaburst, but I can say that SAR wouldn't be less stable.

Does this mean I cannot continue my project with NCS? If disregard the Bluetooth Mesh specification, is there a way to support long messages ? I know the SAR, but it incompatible with instaburst.

Hi,

Nordic Advertiser Extensions (Instaburst) feature is not available in NCS.
