help.... i bought the device SN-FPR-UART & UC00A to develop my access control system.
i tried on sample GUI provided, i am able to reset myself as admin and proceed to set/setup 2-3 set of fingerprints. I believe those fingerprint images already stored into the device's module. When i try to write a program and send to device, it has no reply code per expected. Baud rate setting are both set 19200bps, not sure if there is any setting or parameter to be taken into consideration to get the expected reply code? Any expert pls share some thoughts here.
