Hi all.I experienced very weird situation today.To describe problem briefly,Case 1.1. Xbee is connected via IMU board (4-pin connector)1.1 The other Xbee is connected to the PC.2. USB port on IMU board is connected to the PC for the 5v power.(in this case, battery is unplugged).3. I set the SerXBee in Config.h. So configurator software (Labview thing)will communicate via Xbee.4. PC side Xbee has COM2.5. I turned on configurator, and select COM2, 57600bps, worked.Case 2.1. Xbee is connected via IMU board (4-pin)2. Battery is plugged, 5v source is from ESC.2.1 The only one ESC port is fully connected to ardupilot, the other ESCconnects just signal line (1-line).3. I turned on configurator, and select COM2, 57600bps, but NOT WORKED.So I tested using CLI mode with both configuration (case 1,2).In case 1, the character sent from PC is well passed to arduino board.In case 2, the character seems not received by arduino.Can you guess any problem in this case?
