OK.Thanks.

If you add CONFIG_BT_LL_NRFXLIB (and make sure that CONFIG_BT_LL_SPLIT is not set), the application should use the ble_controller library in nrfxlib.

OK.

Now, I am running my nrf_connect_SDK application on nRF52840.
But, it use open source BLE-stack.

Please tell me how to use ble_controller.(How to change BLE-stack from OSS to proprietary ble_controller.)

[quote user="loquat"]nRF connect SDK not support nRF52xxx[/quote]

At the moment no, but we will start supporting at least some features on the nRF52 series in the future.

Note that this does not necessarily mean that nRF Connect SDK (NCS) applications does not work on the nRF52, just that we have not done much testing and therefore does not guarantee that everything works.

Again, for the moment, this is correct.

However, this will change in the near future. There are a couple of pull requests open that adds nRF53 support for the nRF BLE Controller:

https://github.com/NordicPlayground/nrfxlib/pull/117

You says.

1. nRF connect SDK not support nRF52xxx.
2. ble_controller not support nRF5340.(only supported by Zephyr open-software BLE-stack.)

ask again,
Is ble_controller, In what environment can it be used?

For questions about future plans, you should contact your Regional Sales Manager.

If you do not know how to contact your RSM, you can send me a private message that includes your location.

Best regards,

Are there any plans to produce softdevice for nRF5340 so zephyr is not required?

Zephyr implements both the controller (link) and the host (everything else between the link layer and application layer), with the Host Controller Interface (HCI) between the two layers.

bukinr — Wed, 27 Nov 2019 15:05:44 GMT

Does zephyr implement bluetooth link layer or HCI only?

I am porting my application from SDK15 base to Zephyr base.
The basic part is almost complete.
But I was using timeslotAPI. Zephyr does not have a Timeslot API.
I want to use ble_controller to use TimeslotAPI.
Can my wish come true?

Hi bukinr.

At the moment, the nrfxlib/ble_controller does not support the nRF5340.

Instead, you should use Zephyr's open-source Bluetooth stack for now.

Which version of libble controller (bluetooth link controller) is compatible with nRF5340 ? There are three versions in nrfxlib/ble_controller: 112, 134 and 140

Hi.

You can find documentation about the nRF BLE Controller here: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrfxlib/ble_controller/README.html

[quote user=""]This looks like the library version of SoftDevice.[/quote]

This is mostly correct. However, the BLE Controller is mostly the link layer, while we will use Zephyr's Bluetooth host layer (which has significant contributions from us as well).

However, note the box marked as important:
