JouleScope not recording serial data to jls file?

Hi, I am capturing the serial data (more baud rates would be great)… and it works a treat and is very useful to profiling different stages of power usage.

However the serial data is not being stored to the JLS file. So if I want to return to the trace, I seem to be missing the serial data.

I have tried using the “Save to file” of a completed trace as well as the live record (where I ensures serial and channel “0” where selected… However when opening the files, I can see the trace for channel “0”, but no serial data… i.e. the decoded data and ability to select time ranges based on it.

Am I missing something?

Thanks,
Karl

Hi @KK123 - You are not missing anything. As of Joulescope UI 1.3.4 on 2025-05-19, the Serial Console widget functionality is limited. See GPI UART usage request - #2 by mliberty. We do plan to continue adding more functionality to this feature in the future.

Ah OK… it is a great feature. Please keep enhancing it… It is worth me adding a enhancement request for being able to see decoded serial data for JLS files?

HI @KK123 - You are welcome to add enhancement requests to the Joulescope UI on GitHub.

We do have these two items on our internal future feature list:

  1. UI Serial Console: add configurable baud rate, start bit, and stop bit
  2. UI Serial Console widget: support JLS save/load

If you add these to GitHub, then you will get notified when we add it to a project and work on it. As of 2025-05-19, we have other priorities schedule for the next few months that will prevent us from get back to improving the Serial Console widget.
