Thread Samples not working in one of two nRF5340-PDK

[simon8]

Hi, i have two nRF5340 DK that i'm testing with the Thread CoAP client/server samples.

I found out that with the newer DK, both the clinet and server samples work. With the older, after flashing in the code, it doesn't respond to commands and the leds don't switch on. However if i try to flash the blinky sample in both the DKs, it works!

How is this possible? What i can do to solve this situation?

Thanks

These are the DKSs' informations:

2.0.1

2022.36

1050097428

PAC10095

Hi,

The nRF5340 PDK is not supported in nRF Connect SDK, and you will not get samples or applications using the 802.15.4 radio driver (which is used by Thread) to work with the PDK. Preview DKs have engineering chips, and are lacking several fixes that the final revisions has. They should not be used once we have released a DK. I would suggest getting a DK instead.

Best regards,

Marte
