  • All AT Commands time out in LTE link monitor

kava60 Hey Kurt,

Ahh that’s right. This is the factory test image, it will barf at you because you don’t have anything connected to the UART pins. You can short the TX and RX pins together or download this pre-compiled at_client binary and load it..

https://community.jaredwolff.com/assets/files/2021-05-17/1621218699-636557-at-client.zip

Hopefully that will get you started! I recommend you get your SDK setup that way you can build these examples yourself.

    jaredwolff Jared,
    Thanks I’ll short those pins and try again. That link you provided above downloads something called app_update.bin (not at-client) - should I load app_update.bin?
    I originally loaded the at-client-v1.3.2.bin (the start of this post and saga) and when I connected LTE link monitor, every AT command I would issue would time out. At this point, getting the AT commands working, so I can evaluate the modem is really all I’m trying to do (for now)
    Thanks, Kurt

      jaredwolff Jared,
      Thanks! That worked. So… What is different between loading this “app_update.bin” vs my original attempt loading the at-client-v1.3.2.bin? Curious what I did wrong.
      Kurt

      jaredwolff Jared,
      Never mind - I’m guessing you just rebuilt the at-client sample and the app_update.bin was just the output of the build. I’m working my way through the development environment and building the samples.

        Ok, so I’ve followed the instructions to set up the SDK and when I tried to build the blinky sample it fails (see output below). Sorry to be such a pest - I usually don’t have this much trouble getting going with things…

          kava60 hmmm. Haven’t seen this one before. Are you doing this from a CLI that you opened with nRF Connect? Alternatively you can also run this and it will do the same thing:

          export PATH=/opt/nordic/ncs/v1.5.0/toolchain/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin ; export ZEPHYR_TOOLCHAIN_VARIANT=gnuarmemb ; export GIT_EXEC_PATH=/opt/nordic/ncs/v1.5.0/toolchain/Cellar/git/2.26.2/libexec/git-core ; export GNUARMEMB_TOOLCHAIN_PATH=/opt/nordic/ncs/v1.5.0/toolchain ; clear⏎

          I keep these commands in a file called setenv and then when I want to set my environment I simply run

          source setenv

          This will set the environment variables which may be causing this weirdness.

          You may also have a malformed west.yml. Did you only make the necessary edits to add NFED? Did you have any issues when you ran west update?

            jaredwolff I am running this in the terminal/shell that opens from the nRF connect toolchain manager. I did make the edits to add NFED and didn’t see any errors when I ran west update after making the changes to west.yml.

            I think I’ll see if there is a way to blow away the SDK and reinstall it again to see if that clears up the problem.

            Kurt

            jaredwolff I removed the SDK, reinstalled, modified west.yml and west update. Then tried building the sample again. Same problem. It kind of looks like the failure is because there is a ‘_default_importer’ method that is the default callback invoked when “the source file requires importing manifest data that aren’t found locally”. The default one simply throws the exception. From looking at the API, it looks like the caller of the Manifest API is supposed to provide an ‘importer’ callback if they expect to handle this case (manifest data not found locally). Apparently there isn’t one provided in this case, so the exception is thrown. I’ll keep working my way back from this info to see if I can tell why this is happening. I’m guessing this must be some sort of environmental issue on my system… Sigh.

            Kurt

              kava60 yea it’s likely some type of environment issue. As long as you open a terminal from nRF Connect Desktop or overwrite your path with he commands I gave you earlier it should just work. I’m assuming you have Python installed elsewhere? Do you have any of the Zephyr SDK tools installed? west cmake ninja?

                kava60 also are you doing this within an editor like VSCode? The editor tends to muck with your environment variables as well.

                jaredwolff I do have make installed on my Mac; I have a /usr/local/bin/cmake which reports version 3.19.1. Likely a requirement for something else I develop with. When I do a which cmake in the terminal window created from nRF connect desktop toolchain manager, it reports: /opt//nordic/ncs/v1.5.0/toolchain/bin/cmake so I don’t think it is getting the /usr/local/bin/cmake that is installed on my Mac. A which on west and ninja also reports the same path under /opt/nordic/ncs/v1.5.0/toolchain/bin.

                As for your second question - no, I’m not running any of this in an IDE, just at the shell prompt in the terminal window that is opened (with the correct environment setup) from the nRF connect desktop…

                Kurt

                jaredwolff also, just in case I did a chmod -x on my /usr/local/bin/cmake and tried again - same failure so we can rule out the cmake I have installed on my Mac…
                Kurt

                jaredwolff in case it is useful, doing a west config -l reports the following:

                manifest.path=nrf
                manifest.file=west.yml
                zephyr.base=zephyr

                That looks ok.

                Maybe it’s a weird permissions issue in your /opt/nordic folder? My folder is owned by my user in OS X.

                Is there anything in your opt folder that could have changed things up?

                Also, are you using a newer M1 Mac or Intel based?

                  kava60 hmm the plot thickens then.

                  My best guess is that your nrf/west.yml is malformed. Can you cd to /opt/nordic/ncs/v1.5.0/nrf and run git diff >> nrf.diff and then send nrf.diff my way?

                    jaredwolff I tried the ‘git diff >> nrf.diff’ but that failed. I had saved the original west.yml before I modified as specified in the install instructions, so here is a diff west.yml old_west.yml:

                    38,39d37
                    <     - name: circuitdojo

                    <       path: nfed
                    <       remote: circuitdojo

                      kava60 hmm that look a-ok to me.

                      Since this is clearly related to python/west in some way. You can try compiling “manually”

                      # Use cmake to configure a Ninja-based buildsystem:
                      cmake -B build -GNinja -DBOARD=circuitdojo_feather_nrf9160ns samples/blinky
                      
                      # Now run ninja on the generated build system:
                      ninja -C build

                      Also if there are any examples you want me to pre-build for your evaluation please let me know and I’ll send em your way.
