nRF9160 DK refuses to connect

[Caycee]

I activated the iBasis SIM (Rochester, NY), but LED's 1 and 2 don't blink. LED5 is mostly on solid with a 1-second slight off-pulse.

AT commands from nRF Connect just timeout, so basically it's just not working.

Hi,

Can you describe the steps that you have performed on this DK?

Did you flash the modem firmware?

Which link did you follow to connect the DK to nrfcloud?

We can better assist you if you can provide more details.

I don't remember following any links other than running nRF Connect.

It seems to me something auto-updated the first time I ran it but I don't remember any specifics--it's been a while.

I just ran the programmer and hit 'Read' and got the following:

Hi, 

This only shows that the programmer have access to the chip and has read out chip specific information.

I think it may have done some update for the programmer itself.

It shall not update anything for the chip.

Can you follow this link and make sure you have flashed both the nrf91 application hex file and the nrf91 modem firmware? https://infocenter.nordicsemi.com/index.jsp?topic=%2Fug_nc_programmer%2FUG%2Fnrf_connect_programmer%2Fncp_introduction.html

Which example did you run with?

And can you start from scratch and provide a list of steps that you have performed, if it still fails?

Thanks!
