please people you are the only one can help me. lets start
i have bought RN-41 bluetooth modem (http://gr.mouser.com/Search/ProductDetail.aspx?R=RN-41virtualkey66230000virtualkey765-RN-41).
i connected rx/tx of RN-41 with tx/rx of arduino. so i can have bluetooth communication (i know there is bluetooth arduino version but i want the cheapest way).
i installed the RN-USB-T (http://gr.mouser.com/Search/ProductDetail.aspx?R=RN-USB-Tvirtualkey66230000virtualkey765-RN-USB-T) USB stick in my computer with success
Now the problem:
the problem is that this stick creates 2 ports (COM10,COM11). The first one (COM10) is for sending data and the other one (COM11) is for recieving data. (Arduino finds both of them).
Becouse that i can only send data to arduino with Serial Monitor (arduino succed to read them, i know becouse with a simple code a led, turns on when i send 1 and turn off when i send 0).
But i cant read data from arduino. and i think becouse this modem uses 2 ports of that. (even if i couldnt read from COM11 port.....arggg). I tried with stand-alone arduino and i had the same problem
Is there any solution? please help me. do i need to buy another bluetooth modem? and if yes witch one?
