Showing error : Communication Error

[Repulsar19]

Hello, I'm using a HLK-FPM383F Fingerprint sensor for my project. I'm usning your code for enrolling and deleting the fingerprints images. All my connections are right and also fingerprint sensor is detected as well. But when I enter a slot number, it starts to show 'Communication Error' . What am I missing ? I have uploaded ' Enroll with LED Control' program

Hi, if you still have the problem, can you try git-pulling and re-testing with the latest source?

If the problem still happens:

• change the value of FPM_LOG_LEVEL on this line to FPM_LOG_LEVEL_V_VERBOSE:
  

  FPM/src/fpm_logging.h

  Line 24 in 7ecf348

  #define FPM_LOG_LEVEL FPM_LOG_LEVEL_INFO

• re-upload and redo the test with the Serial monitor open
• paste here the entire contents of the Serial Monitor after the failure happens.

Closing this. You can re-open when you have the requested data, if you still have the problem.
