Hi, I am doing a project. This project has two Arduino+Shield+Xbee. Cases: - Xbee talk with the other Xbee without problem. - Xbee+Arduino talk only one direction. My idea is to send signad from an Arduino to other (bidirectional); only to work in one direction (sometimes A-->B, other B-->A but ONLY ONE). The jumpers are in correct positions.
Can you help me???
