Dear Mailinglist,
I recently bought a Brymen BM257s (DMM) I tried to use with sigrok-cli
and SmuView. But both failed to detect the DMM while scanning. Can
someone point me in the right direction to troubleshoot the issue or
even has an idea what is wrong with my setup/sigrok? I'm a bit lost in
how to fix this issue.
Before starting the scan, I enabled the remote mode with "HOLD + switch on".
The hardware itself seems to be fine. The regular vendor software for
the DMM (Universal Data Logging Systems, Version ver01A8) shows the data
of the DMM as expected.
I can replicate it the issue with sigrok on a (virtual) Windows machine
as well using the 64 bit nightly build of sigrok
(https://sigrok.org/jenkins/job/sigrok-cross-mingw/buildtype=static,debugtype=release,platform=cross-x86_64-w64-mingw32/lastSuccessfulBuild/artifact/sigrok-cli-NIGHTLY-64bit-static-release-installer.exe).
I ran these commands which give me the following output - as normal user
and root.
~~~bash
