Using the at client sample, i get this print :
***** Booting Zephyr OS v1.13.99-ncs1-5904-g71a875c18e2d *****
The AT host sample started
but I cant send any command (no response).
the weird thing is, that I can send commands via asset tracker.
Any idea why ?
already tried erasing flash / resetting
I fought with this for a while also. Can't remember what I did to finally solve it, but using v1.13.99-ncs2 seemed to make things go smoother. It's also possible that I just knew what I was doing a little more by then. Other things.. be sure you have flashed the secure boot (in the ncs2 version, IIRC), then the at host sample. I also erased the entire flash at some point using the nrfConnect app. I think it was called something like flash programmer. You can read, write, erase flash with it.
how can I upgrade to ncs2.
I tried `west update` , didnt work
I didn't have any luck using west and dropped back to using just ninja to build and flash. I think the sequence is: mkdir build && cd build
cmake -DBOARD=nrf9160_pca10090 /path/to/sample/dir
you need to 'git checkout v1.13.99-ncs2' in maybe the zephr dir? and git checkout related versions of the other repos you put under ncs/. Nordic has a page someplace, perhaps a release notes type of page that tells you which versions to use. I can't for the life of me remember where I found it, though.
I am just beginning with the nrf boards myself, so hopefully somebody can chime in with a little more precise answers
