No USB detect when enable CONFIG_BT_LL_SW_SPLIT

[super6602]

Hi, I want to run hci_usb as a USB dongle, and use the CONFIG_BT_LL_SW_SPLIT software based link layer controller on nrf52840dk

But somehow once config as CONFIG_BT_LL_SW_SPLIT, the USB could not be detected by Linux driver

Is there something wrong?

Hi,

 Are you configuring the project, and only setting this option? If yes, then I suspect that the CONFIG_MPSL is still activated at your end. Try also setting this to =n.

 

If it still does not work, can you please provide more detailed logs?

 

Kind regards,

Håkon

It works when CONFIG_MPSL set to n.

What the main usage of option CONFIG_MPSL ? If it would effect the operation when using CONFIG_BT_LL_SW_SPLIT, it could be config dependent when not using NRF library?
