Hi
I try to implement DFU to our application using Mesh_SDK 2.0.1 and
nRF5_SDK_15.0.0
When I use the DFU-Example everything works fine. I then implemented the
DFU-code from the example to our client application to be able to update it
(without provisioning of servers at the moment).
To program the device I use:
cd pc-nrfutil-mesh_dfu
nrfutil dfu genpkg --application
../../Source/connectivity_client/build/connectivity_client_Debug/connectivit
y_client.hex --company-id 0x00000059 --application-id 1
--application-version 1 --sd-req 0x00A9 --mesh client.zip
cd dfu
python device_page_generator.py -d nrf52840_xxAA -sd "s140_6.0.0" -o
../client.hex
cd ..
nrfjprog --eraseall
nrfjprog --program
../../Mesh_SDK/bin/softdevice/s140_nrf52_6.0.0_softdevice.hex --chiperase
nrfjprog --program
bootloader/mesh_bootloader_serial_gccarmemb_nrf52840_xxAA.hex
nrfjprog --program
../../Source/connectivity_client/build/connectivity_client_Debug/connectivit
y_client.hex
nrfjprog --program client.hex
nrfjprog --reset
For DFU I use:
cd pc-nrfutil-mesh_dfu
nrfutil dfu genpkg --application
../../Source/connectivity_client/build/connectivity_client_Debug/connectivit
y_client.hex --company-id 0x00000059 --application-id 1
--application-version 2 --sd-req 0x00A9 --mesh client.zip
cd dfu
python device_page_generator.py -d nrf52840_xxAA -sd "s140_6.0.0" -o
../client.hex
cd ..
nrfutil --verbose dfu serial -pkg client.zip -p COM19 -b 115200 -fc --mesh
This seems to work in the beginning, but then throws an error:
Flushing com-port...

Failed to upgrade target. Error is: Device returned status code
ERROR_INVALID_DATA (135) on a DFU data packet.
What could be the problem here?
Kind regards
