For troubleshooting purposes, the modules are only 4 feet apart. All functions correctly, but if I cover one of the XBEE modules with my hand without touching any parts, I get intermittent data dropouts (meaning the receiver fails to receive data). If I move away my hand, all functions normally. The spec for range states 300 feet indoor, 1 mile outdoor.
Could a degradation in XBEE performance be caused by my wireless router and/or Apple TV devices (3 total)?
Any XBEE setting or other tip to prevent or reduce these dropouts?
