Following is the error message shown in edge impulse studio

Kindly advise.

Hi @paulphilip, indeed a bug in the latest data forwarder release. We’ve released v1.6.3 which mitigates the issue.

Hi @janjongboom
Yes Its working now. Can you also add a field to specify the unit of the axes in the next release?
