Remote firmware update throws could not read device hardware version.

[csstudent321]

When i tried firmware update to RemoteXBeeDevice throws could not read device hardware version.

and i cannot get a response from returns none remote_xbee.get_firmware_version() remote_xbee.get_hardware_version()

my code looks like:

SERIAL_PORT = "COM10"
BAUDRATE = 9600

TARGET_XBEE = "0013A20041C63024"

XML_FIRMWARE_FILE = "ota-firmware/XB3-24Z_100B-th.xml"
OTA_FIRMWARE_FILE = "ota-firmware/XB3-24Z_100B-th.ota"
OTB_FIRMWARE_FILE = "ota-firmware/XB3-24Z_100B-th.otb"

def main():
    local_xbee = XBeeDevice(SERIAL_PORT, BAUDRATE)
    try:
        local_xbee.open(force_settings=True)
        # Obtain the remote XBee device from the XBee network.
        remote_xbee = RemoteXBeeDevice(local_xbee, XBee64BitAddress.from_hex_string(TARGET_XBEE))
        print(remote_xbee.get_protocol())
        print(remote_xbee.get_firmware_version())
        # remote_xbee = xbee_network.discover_device(REMOTE_NODE_ID)
        if remote_xbee is None:
            print("Could not find the remote device")
            exit(1)

        print("Starting firmware update process...")
        remote_xbee.update_firmware(
                                    XML_FIRMWARE_FILE,
                                    xbee_firmware_file=OTA_FIRMWARE_FILE,
                                    bootloader_firmware_file=OTB_FIRMWARE_FILE,
                                    progress_callback=progress_callback)
        # update_remote_firmware(remote_xbee,
        #                        XML_FIRMWARE_FILE,
        #                        ota_firmware_file=OTA_FIRMWARE_FILE,
        #                        otb_firmware_file=OTB_FIRMWARE_FILE,
        #                        progress_callback=progress_callback)
        print("Firmware updated successfully!")
    except (XBeeException, FirmwareUpdateException, OperationNotSupportedException) as e:
        print("ERROR: %s" % str(e))
        exit(1)
    finally:
        if local_xbee is not None and local_xbee.is_open():
            local_xbee.close()

def progress_callback(str_calback, percent_calback):
    print(str_calback + " %" + str(percent_calback))

if __name__ == '__main__':
    main()

my output is :

raise ATCommandException(cmd_status=response.status)
digi.xbee.exception.ATCommandException: There was a problem sending the AT command packet.
ERROR: Could not read device hardware version

Hi @csstudent321 ,

We could update a remote node using your code above without problems. The instruction print(remote_xbee.get_firmware_version()) prints None since the remote is not initialized. See below.

Before running, ensure the remote node:

1. is in the same network as the local one
2. is not sleeping

# python test_216.py
XBeeProtocol.ZIGBEE
