direction_finding_connectionless_rx: bt_le_scan_start failed, error -EIO

[无效]

Hi, I download nrf connect SDK v2.1.1 through nRF Connect for Desktop,

and I flashed the sample direction_finding_connectionless_rx with noting changed.

Then there is an error.

*** Booting Zephyr OS build v3.1.99-ncs1  ***
Starting Connectionless Locator Demo
Bluetooth initialization...success
Scan callbacks register...success.
Periodic Advertising callbacks register...success.
Start scanning...failed (err -5)
Waiting for periodic advertising...`

But nrf connect SDK v2.1.0 is ok.

Hi Ji, 
There are 2 direction_finding_connectionless_rx  example in the SDK. Have you made sure you run the one made by Nordic , located at \nrf\samples\bluetooth\direction_finding_connectionless_rx
In my test here the example located at \zephyr\samples\bluetooth\direction_finding_connectionless_rx has the same problem as yours but the one located inside nrf doesn't have the problem.
