I am having the worst luck getting my xbees to establish a reliable connection. I'm using a 2 XBee pro s1 one connected to my computer with a SparkFun XBee Explorer Dongle and the other attached to an arduino using a SparkFun XBee Shield which is being powered by an external 7.4v 1300ma battery. I've gone through all of sparkfun's xbee tutorial. I can get them to connect but the signal is very weak. I'm supposed to be getting a range of 1 mile line of sight but I'm only getting a maybe 100 feet line of sight. I've been looking all over the internet for a solution for the past 2 days but can't find any reason for such a low signal range. In xtcu's networking tab it says that the signal quality is unknown. Does anyone have any ideas?
