I have the XCTU software running on my PC.
Our configuration has a wireless sd shield mounted on an Arduino mega2560 board. The switch on the shield is set to USB, and the atmega microcontroller is programmed with an empty design.
The XCTU software is not able to find the XBee module. I notice that the baud rate of the TX pin (XBee output) of the XBee module is at 115,200 baud. I tried to use the 115,200 in XCTU, but it still does not recognize the device.
When I try to use the recover utility in XCTU, the tool says that no bootloader is loaded. Does this tell us something? Do I need to load a bootloader?
How can I figure out the cause of this behavior?
Do you recommend that I connect a USB-RS232 chip (like one from FTDI) directly to the RX and TX pairs of the XBee module and run the XCTU utility? I don't know the data being sent out the USB, only that the USB chip's TX LED is blinking every now and then.
Have you seen behavior like this before? What was the cause then?
