Xbee RX-TX Sync with Biometric Fingerprint

Hello,

I'm workin on my graduation project and I am having trouble to analyse the received data. I am using a biometric reader, where there is no interruption to know when the data arrived. At the same time I need to verify if any event has arrived through Xbee. My idea was to make two methods with a regular period of time, but it didn't work as I expected. Could anyone please help me so that I can receive data from the coordinator that is connected on the computer, and also from the biometric reader that is directly connected on the arduino and doesn't have interruption?
Thanks in advance

Well when you put a finger on it does it give some information on is serial Port output?(I'm assuming it has a Serial Port, please confirm this)
If so one way to check is get a function on the main loop looking for some serial data, when something arrives on arduino port from the fingerprint sensor put all raw data in an array and then sort it of and compare.
I belive there is an interrupt on Serial Port you can also use to jump to a function when someting enter on serial buffer.This way you can have your main loop doing another things if this is important
Of course you could get more eficient ways to do this, consider this just an idea :smiley:
Someone else will give you more tips in this great comunity

Well, I went ahead and try it anyway, and it works. I put 0.1 headers on the bottom and connected it to a microcontroller, provided 3.3v and it seems to work just fine.

wtf??
I don't understand your post with the problem Posted by kiwoxox!

I've seen a number of rather random posts like that this morning. I wonder if there is some sort of spambot thing going on.
