  • XBee S2C: Remote firmware updates

Update the firmware of a local XBee

The firmware update process of a local XBee is performed over the serial connection. For this operation, you need the following components:

  • The XBee object instance or the serial port name where the device is attached to.

  • The new firmware XML descriptor file.

  • The new firmware binary file (*.gbl)

  • Optionally, the new bootloader binary file (*.gbl) required by the new firmware.

Warning

Firmware update will fail if the firmware requires a new bootloader and it is not provided.

Warning

At the moment, local firmware update is only supported in XBee 3, XBee 3 BLU, XBee RR, XBee XR 868/900, and XBee SX 868/900 MHz devices.

Example: Local Firmware Update

The XBee Python Library includes a sample application that displays how to perform a local firmware update. It can be located in the following path:

examples/firmware/LocalFirmwareUpdateSample/LocalFirmwareUpdateSample.py

Update the local firmware using an XBee object

If you have an object instance of your local XBee, call the update_firmware() method of the XBeeDevice class providing the required parameters:

Method

Description

update_firmware(String, String, String, Integer, Function)

Performs a firmware update operation of the local XBee.

  • xml_firmware_file (String): path of the XML file that describes the firmware to upload.

  • xbee_firmware_file (String, optional): location of the XBee binary firmware file (*.gbl).

  • bootloader_firmware_file (String, optional): location of the bootloader binary firmware file (*.gbl).

  • timeout (Integer, optional): the maximum amount of seconds to wait for target read operations during the update process.

  • progress_callback (Function, optional): function to execute to receive progress information. Receives two arguments:

    • The current update task as a String

    • The current update task percentage as an Integer

The update_firmware() method may fail for the following reasons:

  • The device does not support the firmware update operation, throwing a OperationNotSupportedException.

  • There is an error during the firmware update operation, throwing a FirmwareUpdateException.

  • Other errors caught as XBeeException:

    • The device is not open, throwing a generic XBeeException.

    • The operating mode of the local XBee is not API_MODE or ESCAPED_API_MODE, throwing an InvalidOperatingModeException.

Update local XBee firmware using an XBee object

Update the local firmware using a serial port

If you do not know the XBee serial communication parameters or you cannot instantiate the XBee object (for example, if the device must be recovered), you can perform the firmware update process by providing the serial port identifier where the XBee is attached to.

In this scenario, use the update_local_firmware() method of the XBee firmware module providing the required parameters. The library forces the XBee to reboot into bootloader mode, using the recovery mechanism, and performs the firmware update from that point.

Method

Description

update_local_firmware(String or XBeeDevice, String, String, String, Integer, Function)

Performs a local firmware update operation in the given target.

  • target (String or ``XBeeDevice`): target of the firmware upload operation. * String: serial port identifier. * ``XBeeDevice`: the XBee to upload its firmware.

Example: Remote Firmware Update

The XBee Python Library includes a sample application that displays how to perform a remote firmware update. It can be located in the following path:

examples/firmware/RemoteFirmwareUpdateSample/RemoteFirmwareUpdateSample.py

Update the XBee file system

XBee 3 and XBee RR devices feature file system capabilities, meaning that they are able to persistently store files and folders in flash. The XBee Python Library provides classes and methods to manage these files.

Warning

At the moment file system capabilities are only supported in XBee 3 and XBee RR devices.

Create file system manager

A LocalXBeeFileSystemManager object is required to work with local devices file system. You can instantiate this class by providing the local XBee object. Once you have the object instance, you must call the connect() method to open the file system connection and leave it ready to work.

Warning

File system operations take ownership of the serial port, meaning that you will stop receiving messages from the device until file system connection is closed. For this reason, it is recommended to call the disconnect() method of the file system manager as soon as you finish working with it.

Method

Description

connect()

Connects the file system manager.

disconnect()

Disconnects the file system manager and restores the device connection.

The connect() method may fail for the following reasons:

  • The device does not support the file system capabilities, throwing a FileSystemNotSupportedException.

  • There is an error during the connect operation, throwing a FileSystemException.

Create a local file system manager

from digi.xbee.filesystem import LocalXBeeFileSystemManager

[...]

# Instantiate a local XBee object.
xbee = XBeeDevice(...)

[...]

# Create the file system manager and connect it.
filesystem_manager = LocalXBeeFileSystemManager(xbee)
filesystem_manager.connect()

[...]

filesystem_manager.disconnect()

Update multiple nodes

The XBee Python Library provides a mechanism to update several nodes at once. For this, define the update tasks to perform. An update task includes:

  • The node to be updated, local or remote.

  • The required file(s) for the update.

  • Other parameters such as the timeout or a callback to notify the progress.

There are two types of update task:

  • A FwUpdateTask defines a firmware update task for a local or remote node.

from digi.xbee.firmware import FwUpdateTask

[...]

XML_FIRMWARE_FILE = "/home/user/my_firmware.xml"
XBEE_FIRMWARE_FILE = "/home/user/my_firmware.gbl"
BOOTLOADER_FIRMWARE_FILE = "/home/user/my_bootloader.gbl"

[...]

# Instantiate an XBee object.
xbee = XBeeDevice(...)

[...]

# Define an update progress callback for the firmware update task
def my_fw_update_cb(task_msg, percentage):
    print("%s: %%d" %(task_msg, percentage))

# Define a firmware update task for the local node
fw_update_task = FwUpdateTask(xbee, XML_FIRMWARE_FILE,
                              fw_path=XBEE_FIRMWARE_FILE,
                              bl_fw_path=BOOTLOADER_FIRMWARE_FILE,
                              progress_cb=my_fw_update_cb)

[...]

  • A ProfileUpdateTask defines a profile update task for a local or remote node.

from digi.xbee.firmware import ProfileUpdateTask

[...]

PROFILE_PATH = "/home/user/my_profile.xpro"

[...]

# Get the remote node.
remote = ...

[...]

# Define an update progress callback for the profile update task
def my_profile_update_cb(task_msg, percentage):
    print("%s: %%d" %(task_msg, percentage))

# Define a firmware update task
profile_update_task = ProfileUpdateTask(remote, PROFILE_PATH,
                                        progress_cb=my_profile_update_cb)

[...]

You can define as many update tasks as you need. Then use the update_nodes() method of the XBeeNetwork to perform all of them.

Method

Description

update_nodes(List)

Performs the provided update tasks. It blocks until all tasks finish.

  • task_list (List): List of FwUpdateTask or ProfileUpdateTask to perform. The method returns a dictionary with the 64-bit address of the XBee as key and, as value, a Tuple with the XBee (XBeeDevice or RemoteXBeeDevice) and an XBeeException if the process failed for that node (None if it successes)

Update several nodes

from digi.xbee.firmware import ProfileUpdateTask

[...]

ROUTER_PROFILE_PATH = "/home/user/my_routers_profile.xpro"

[...]

# Instantiate a local XBee object.
xbee = XBeeDevice(...)

# Get the network.
xnet = xbee.get_network()

[...]

profile_tasks = []
for node in xnet.get_devices():
    if node.get_role() != Role.ROUTER:
        continue
    profile_tasks.append(ProfileUpdateTask(remote, ROUTER_PROFILE_PATH))

update_result = xnet.update_nodes(profile_tasks)

for task in tasks:
    res = update_result.get(str(task.xbee.get_64bit_addr()), None)
    res_msg = "OK"
    if res and res[1]:
        res_msg = "ERROR: %s" % str(res[1])
    print("%s: %s ---> %s" % (task.xbee, task.profile_path, res_msg))

[...]

To receive the status of the update process per node, provide a callback using the add_update_progress_callback() method. This callback receives three arguments:

  • The XBee being updated, local or remote.

  • An UpdateProgressStatus with the current status.

Register an update progress callback

[...]

xnet = xbee.get_network()

[...]

profile_tasks = ...

# Define the update progress callback.
def cb_update_progress(node, progress_status):
    print("%s %s - %s: %d%%" % (progress_status.type, node,
                                progress_status.task, progress_status.percent))
    if progress_status.finished:
        print("---- %s finished for %s ----" % (progress_status.type, node))

# Add the update progress callback.
xnet.add_update_progress_callback(cb_network_modified)

update_result = xnet.update_nodes(profile_tasks)

[...]

To stop listening to update progress events, use the del_update_progress_callback() method to unsubscribe the already-registered callback.

Deregister an update progress callback

[...]

def cb_update_progress(node, task_str, percentage):
    [...]

xbee.add_update_progress_callback(cb_update_progress)

[...]

# Delete the callback.
xbee.del_update_progress_callback(cb_update_progress)

[...]
