How to receive HCI events in a single thread with nrf connect SDK

[loquat]

I am planning to migrate from the nRF5 SDK to the nrf connect SDK.

My application is processing events from SoftDevice on a single thread.

In the same way, please tell me how to receive HCI events in a single thread with the nrf connect SDK.

[loquat]

yes. I understand It.

What I am concerned about is which thread (Context) is calling the callback when it is called back using the Bluetooth Host API.

I expect all callbacks to be called from SystemWorkq.

Was your question addressed by Amanda's reply in your other thread here:  Why is ble_rx_thread priority cooperative?  

[loquat]

No.

my question is

1. How all HCI events are called on SystemWrokq context (this thread)

2. How to set SystemWorkq priority to preemptive (other thread)

What thread/workqueue they are run in depends on your configuration settings here: https://github.com/nrfconnect/sdk-zephyr/blob/main/subsys/bluetooth/host/Kconfig#L97. You can open the thread viewer when debugging the application in VS code or Segger Ozone to confirm what thread a particular callback is run in. 

E.g.
