Account cancelled 2022-01-28 03:56:14 270 Views1 Replies Hello everyone, I Bought SEN0188 sensor and I tried to use but its give error: "Did not find fingerprint sensor 
". After some search and datasheet checking, I Finded error and updated "FINGERPRINT_VERIFYPASSWORD". After some usage and testing. I finished project, I put in the box and after some trying, I again getting to "Did not find fingerprint sensor " again. I checked my code, wiring shematic and etc.. But doesnt working.

This looks like a bad connection somewhere in the wiring. It is recommended to replace the wire, or use a multimeter to test the circuit.
