Weird problem again.
XBee works fine both receiving and transmitting with power from USB-> APM -> XBEE and
5V Battery-> Receiver -> APM-> XBEE
But when using with ESC or BEC it only works transmitting data from APM to my PC.
But not the other way around. When i send something from my PC to APM the ASC/RSSI on XtreamBee board light up.
I'm using XBEE PRO 2.4.
I'm setting Baudrate in the ArducopterNX to 111111 and PC to 115200 with 2 stopbits.
Any suggestions would be greatly appreciate.
