This is a fork of anszom's fork of
Nordic's nrfutil. Whereas
anszom's fork adds support for OTA DFU via. a native bluetooth device using
BLE_GATT, this fork attempts to do the
same using bluepy.
$ [sudo] python setup.py install
The bluepy transport backend has not yet :been added to the nrfutil CLI
tool. However, after installation, the functionality can be accessed via the
python package:
from nordicsemi.dfu import dfu, dfu_mode_jumper
ZIP_FILE_PATH = "foo-dfu_package.zip"
ADDR = "XX:XX:XX:XX:XX:XX"
# setup buttonless jumper and extract dfu transport from it.
jumper = dfu_mode_jumper.DfuModeJumper(ADDR)
my_transport = jumper.intoDfuTransportBluepy()
my_dfu = dfu.Dfu(ZIP_FILE_PATH, my_transport, 0)
# initiate jump to DFU mode, after which ADDR should disconnect.
jumper.jump_to_dfu_mode()
# at this point the device with address ADDR should be disconnected.
my_dfu.dfu_send_images()
For the time being, the jumping to DFU mode is its own module separate from the
actual DFU, to better be able to test against anszom's fork, which assumes
that the device is already in DFU mode. The DfuModeJumper also includes a
.intoDfuTransportNative() for use with anszom's DfuTransportBleNative.
Below is a copy of Nordic's original README.
nRF Util is a Python package and command-line utility that supports Device Firmware Updates (DFU) and cryptographic functionality.
See the InfoCenter pages for information on how to install and use nRF Util.
