Thanks for being part of the GitHub Community Forum! We're glad you're here.
I wanted to jump in here, and mention that if you don’t get the help you’re looking for from this particular community, you might want to try getting help somewhere that focuses on R305 Fingerprint Module. It's definitely possible another GitHub user might have run into this same issue and can help, but the GitHub Community Forum focuses primarily on topics related to GitHub itself or collaboration on project development and ideas. We want to make sure you're getting the best support you can, but this forum may not be the right place for this particular topic.
Best of luck!
