Check out the note given here https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/ug_nrf5340.html#working-with-nrf53-series

"See the nRF Connect SDK v1.4.0 documentation for the last release supporting the nRF5340 PDK."

Best regards,

so per "d_c_h_w" and mine findings, SDK1.5.0 BLE functionality is not working for the NRD5340, when can we expect SDK1.5.1? (or a fix to this issue )

thank you

I wouldn't say 1.5.0 and DK work, as there are several other issues I have encountered moving to 1.5.0. Currently I see the network core trigger "<err> hci_rpmsg: No available command buffers!" and the application core hit an assertion and reboot when trying to read several characteristics straight after connection, so I think I'll be waiting for a 1.5.1

so just to clarify:

1.5.0 SDK+ dk - works

1.5.0 SDK+ pdk - does not work

right ?

after more testing, 1.4.9 works OK , there is an issue with BLE on PDK + 1.5.0

What board version of the n5340 (P)DK do you have? Do you have a PDK or a DK? - PDK
What board name do you use for building the samples? If you use west could you provide the command, and if you use SES, could you provide the nRF Connect Options? - , nrf5340pdk_nrd5340_cpuapp
What NCS version are you using? SDK1.5.0

reading the commect below I do suspect it's an issue with 1.5.0 SDK since this worked with some olfer version (not sure what )

I'm seeing this too since upgrading to 1.5.0 SDK. I have tried on both PDK and DK boards. This seems to happen also with the samples e.g. I tried the zephyr hr peripheral sample and it does this too

I think the ECC HCI warning may be benign, as connection works on the DK board, but it still shows this message.

So issue may only affect PDK versions
