Projects › Projects › Communicating with R303A fingerprint reader module › Hello Friends, I am using
I am using r303a fingerprint module for biometric voting.
But, when I connect the module with the pc , and try to open the device, I get the following message:-
” Open Device Fail, please check the device address and passward”.
I also tried to communicate with the device using ” advanced serial port terminal” and when I give the instruction to read system parameters, I receive”f f f f f f f f”.
Please help me out as I am stuck in this problem.
Thanks in advance:-
