XBee and Ucam III

I am using a legacy S1 XBee connected to a PCA grove development board.
Using the software with the Ucam in question im attempting to usethe XBee as a serial connection to the camera. the problem is that I see the TX light flashing so that I know the command is going in but the RX light isn’t flashing signaling that it is being forwarded to the camera, how can I use the XBee to forward this signal?
