Thanks Neso for your time. Actually I passed the tests and got the certificate without this test.

Anyway I will try it using my Thingy91 when I find some time.

Thank a lot

Regards

So this was actually working. The green led is so bright, it's hard to see the yellow turn on/off.

Hello,

Difficult to tell from the information provided. Do you have any logs trom the nRF9160 kit itself? What version of the nRF Connect SDK are you running and with what modem fw on your device?

Kind regards,
Øyvind
