Re: [Bluetooth] Is BT 5.0 specific features supported by Zephyr for nRF52840 board yet?

Hi Anupam,

 

All the features you mention are supported on the nRF52840 *except* LE Extended Advertising.

I suggest you take a look at the controller feature list in order to enable/disable particular features. You can do that by editing your prj.conf and adding the missing options.

 

https://github.com/zephyrproject-rtos/zephyr/blob/master/subsys/bluetooth/controller/Kconfig#L252

https://github.com/zephyrproject-rtos/zephyr/blob/master/subsys/bluetooth/controller/Kconfig#L252

https://github.com/zephyrproject-rtos/zephyr/blob/master/subsys/bluetooth/controller/Kconfig#L267

 

LE Extended Advertising will probably come after some additional required refactoring that is going on at the moment.

 

Contributions welcome!

 

Regards,

 

Carles

Subject: [Zephyr-devel] [Bluetooth] Is BT 5.0 specific features supported by Zephyr for nRF52840 board yet?

 

Hello Zephyr Developers,

 I am looking for zephyr based application for verifying BT 5.0 specific features like LE Extended Advertising, LE Long Range (2M PHY), LE High Speed (2M PHY) etc. on my nRF52840 PDK board.

Currently, I have compiled samples/bluetooth/hci_uart and burnt the zephyr.hex in nRF52840 PDK board.

However, it does not support BT 5.0 specific features mentioned above. My intention is to use Bluez upstream in my Host PC (RPI3 with Raspbian Distribution) and nRF52840 SOC as my BT controller.

Could someone provide some insights if such support is available somewhere or if not, then when will such support be available?

When I use hciconfig hci1 commands, I get following list of Supported commands in btmon
