I am creating a wireless control using the xbee shield on top of an arduino as the controller, and a PC application (Processing) + Xbee module as interface.
I managed to get a communication up and running, even using zigbee.
My problem is that in my PC application has a couple of sliders for setting some remote values on the controller. It works, but sometimes it takes very long (up to 10s) before I receive an acknowledge from my controller.
If I remove the xbee shields and do a direct serial communication it goes all very well. I use a baudrate of 19K2.
can anyone help?
