Hi!

I'm trying to receive data from a sesnor in an Arduino UNO over H05 module using a dongle in my PC. When I receive data in Putty software there is no problem but when I try to establish the communication using matlab, no data is being received. Any idea of the problem? I've attached the error in Matlab in order to give further details.

Serial Port Object : Serial-COM14
     Communication Settings 
        Port:               COM14
