Group...So I am still having xbee issue on the drone side, I remembered I connected the usb while connected to the xbee to check the firmware update and load a pid setup file, it wouldn't load through xbee. Is this normal? flight planner disconnected from xbee and connected through the usb no problem, then wouldn't reconnect to xbee.. could this have disconnected/interfered with the apm 2 connecting to the xbee modules somehow? I am goiing to order some new DIY adapters so I can be sure if it is the ftdi adapter and have a second usb to test the modules with. It will kill me if it is on the APM side somehow. Any thoughts folks?
