Question related to binary data parsing/visualization in the GPL3 version

[SvenNouwens]

I'm trying to get the hexadecimalADC example running, but I have no success so far. I'm regularly sending the poll-data command to a micro controller that responds wit a correct data packet. This is just copy-pasting from the example code. The problem is that the dashboard with the plots does not show up.

When accessing the project editor, the binary data parsing is linked to the pro-version "warning", so I was wondering if this example is even supposed to work on the GPL3 version. I was unable to get an answer for this based on the information I was able to find.

Hi,

Thanks for reporting this issue and for your patience! I've identified and fixed two critical bugs in v3.2.1 that were preventing the hexadecimalADC example from working:

1. Frame delimiter bug (introduced in v3.2.0): The frameStart and frameEnd sequences were incorrectly swapped when using hexadecimal delimiters, causing frame detection to fail completely.
2. GPL3 decoder limitation: The GPL3 version previously only supported plain text parsing. I've now enabled hexadecimal, binary, and Base64 decoders in the GPL3 build, so the hexadecimalADC example (which uses the binary decoder) should work out of the box.

I'm currently waiting for the CI builds to finish before publishing the bugfix release. If you're still seeing issues after updating, please let me know!

Wishing you happy holidays and a great start to the new year!

Thanks,
Alex

Did not expect such a swift reply during this time of year! I'll make sure to test the bugfix release and report on the results.

Best wishes for you too.

ADC example works in the 3.2.1 release.

One additional thing came to mind when building the project again.
During the cmake configuration, I got the error that I cannot find the following policy "CMP0167" (using in lib/mdflib)
This is apparently a new policy in cmake 3.3.0, but the most recent version I got easily get through apt is 3.28, so I commented the offending line and everything worked as expected.

This issue sort of fixes itself when cmake 3.3.0 gets more widespread I'd recon, so more of an FYI.
