I am using XBEE S2C module as a coordinator,router and end device. My products are in ready to dispatch state, but I am facing a problem of range.
Two end devices are kept at same positions besides each other and coordinator at a fix location. Both the End devices being at same position they show different RF strength. There is also a variation in the RF strengths of individual devices(approx 20%). Now among the two end devices one is showing 20% range and other 4%.
How such things can result in so much of difference.
What are things i may have missed out to be done for XBEE settings. Or some things i may have not noticed which can be the reason for this.
