XBee Configuration

PAN Transparent mode / X-CTU

Installation

  1. Download the X-CTU Utility from the Digi Website
  2. Download the configuration files for your module (selection wizard)
  3. Install the X-CTU Utility, then switch to the Modem Configuration tab.
  4. Click on the rightmost button Download new versions…
  5. Click on File… and select the downloaded ZIP file from step 2)
  6. X-CTU should confirm the import of several new modules

Flashing the Groundstation module

NEW MODULES HAVE 9600 BAUD PER DEFAULT, CONFIGURED ONES TYPICALLY 57600. ONCE CONNECTED CLICK ON <READ> IN THE MODEM CONFIGURATION TAB FIRST.

  1. Now put the groundstation module in the USB XBee Explorer.
  2. Select the function set ZNET 2.5 COORDINATOR DEVICE AT or ZIGBEE COORDINATOR DEVICE AT. The Mesh XBee modules (XBP24-DM) have slightly differently named settings.
  3. Set the pan id to 105 (or an other number, must be the same as the pan id of the end device). The PAN ID setting for XBP24-DM is named “Modem VID”.
  4. Set the Destination Address Low (DL) to FFFF.
  5. Set the Node Identifier to “GROUNDSTATION” or another name.
  6. Set the baudrate you want to use. The groundstation and the MAV module should have the same baudrate. Also you need to know what Baudrate the current attached XBee has. 57600 is the maximum baudrate setting for bidirectional transfers to work correctly. At a higher baudrate setting, transmission can only be done in one direction.
  7. Then write the firmware to the module.

Flashing the Onboard / MAV module

NEW MODULES HAVE 9600 BAUD PER DEFAULT, CONFIGURED ONES TYPICALLY 57600. ONCE CONNECTED CLICK ON <READ> IN THE MODEM CONFIGURATION TAB FIRST.

  1. Put in the second module in the USB XBee Explorer. This will be the module for the end device.
  2. Start the X-CTU programm and go to the modem configuration.
  3. Select the function set ZNET 2.5 END DEVICE AT or ZNET 2.5 ROUTER/END DEVICE AT. The Mesh XBee modules (XBP24-DM) have slightly differently named settings.
  4. Set the pan id to 105 (or an other number, must be the same as the pan id of the coordinator). The PAN ID setting for XBP24-DM is named “Modem VID”.
  5. Set the Node Identifier to “ONBOARD” or another name.
  6. Set the baudrate you want to use. The groundstation and the MAV module should have the same baudrate. Also you need to know what Baudrate the current attached XBee has. 57600 is the maximum baudrate setting for bidirectional transfers to work correctly. At a higher baudrate setting, transmission can only be done in one direction.
  7. Then write the firmware to the module.

Connecting the XBee module to your MAV

Now you have to connect the MAV module to your board. You just need four wires. One for ground, one for high level, one for RX and TX. Connect the DIN pin from the XBee module to the TX pin of your board and connect the DOUT pin with the RX pin.
