Hello,
Which board to use with nRF connect. You can find the list of supported boards here: nRF Connect Bluetooth Low Energy
Best regards,

I use the nrf5340dk, when I open the BLE app,It came out like this, does it look like a J-LINK problem?
Many thanks

Now I have switched to another 5340 board for the BLINKY test and the results are still the same, I think there is something wrong with the SAMPLE code or it does not apply to the 5340

Please try to build and program the blinky sample in /ncs/zephyr/samples/basic/blinky. Alternatively, send me the project you are using now so I can try it here.
this is the project I am using, I'll try your way.

okey, now it is working~ but how can I find the device on the phone with the nrf connect for mobile app?
Many thanks

You have to select one of the Blueooth peripheral samples here https://developer.nordicsemi.com/nRF_Connect_SDK/doc/2.0.0/nrf/samples/samples_bl.html if you want to test BLE connectivity with your phone. The blinky sample does not include Bluetooth at all.

Thanks. I tried the bluetooth peripheral_uart,but when I build the application this error happened.
FATAL ERROR: command exited with status 1: 'd:\nrfconnect\NRF\toolchains\v2.0.0\opt\bin\cmake.EXE' --build 'd:\nrfconnect\project\peripheral_uart\build'
Does this look like something has gone wrong with CMAKE?
Many thanks

Please post the full log. A screenshot that shows your vs code window may also be helpful.
here y are
Please upload the complete log in a text file. Your screenshot is only showing the end of it.
maybe this txt gonna work
