Is there any USB dongle can be used to test BLE function of chip nRF54L15?

Hi, is it possible to assign a FAE from ShenZhen in China? Then I can contact him/her directly.

And the below landline is always no answers.

By dongle I was referring to the nRF52840 Dongle:

A nRF52 series development kit can also be used instead of the dongle.

The samples I mention are application code running on both the nRF52840 dongle and the nRF54L15:
The code can be found in the nRF Connect SDK:

Hi,

You can use the radio test sample for testing RX performance by counting packets. Both the device under test and a dongle or DK must be running the radio test sample:
https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/samples/peripheral/radio_test/README.html#testing_with_another_development_kit

This can however only work for counting the number of packet received and will not give you the RSSI of the received packet.

If you just need the RSSI and channel you can use the RSSI Viewer application in nRF Connect for desktop. This gives you the RSSI for all the BLE channels, so it will pick up any RF radiation in the 2.4GHz band, like other BLE devices or WiFi.

The Direct test mode application in nRF connect for desktop can also be used for testing, both the DK/dongle and the device under test must be running the direct test mode sample:
https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/samples/bluetooth/direct_test_mode/README.html#testing_with_direct_test_mode_app
