need help on multiple things
All work is on the DK 840 board using sdk15.3
Started with this link
https://rigado.zendesk.com/hc/en-us/articles/360025376053-Add-Nordic-DFU-to-a-SDK-Example
I use this for the 15.3 problem and can get things working using the following in the make file
devzone.nordicsemi.com/.../178253
flash_bootloader: default
@echo Flashing: $(OUTPUT_DIRECTORY)/nrf52840_xxaa_s140.hex
nrfjprog -f nrf52 --recover
nrfjprog -f nrf52 --program $(SDK_ROOT)/components/softdevice/s140/hex/s140_nrf52_6.1.1_softdevice.hex --chiperase
nrfjprog -f nrf52 --program $(OUTPUT_DIRECTORY)/nrf52840_xxaa_s140.hex -r
I get DfuTarg to work with and without bonds
I can DFU the application only zip file to the DK and all works. After done start scan the the app is working
I move on to buttonless dfu using the rigardo URL above
I create the settings hex files using the rigardo URL above
The following commands do not work in that nothing is advertised.
nrfjprog --recover
nrfjprog --program bl_set_s140_app.hex
issues here:
I figure it is due to the SDK15.3 issue in the second URL used
So I go back to DfuTarg with or without bonds as both work the same.
I then DFU load the zip file that includes the app with the bond/lesc using the ble_app_hrs product.
It again comes up and I bond the device, I then start the DFU action.
The DK tries a couple of times but always disconnects
look at line 70: It shows the DFU starts the firmware file is opened:
line 83 it jumps to the bootloader
line 106 it connects to the dfu target
This is where it always seems to disconnect: This is both using bonded and unbonded BL and app
Question:
How can I get the RTT JLink to post info after the unit disconnects and reconnects when it enters the DFU service started from the app
Also I need to be able to get the settings.hex files to work under sdk15.3
Also I need to understand as to what can cause the DISCONNECTED state when entering the DFU service
Line 107 in the log shows false for autoconnect. I will try setting that to true.
Any help would be appreciated.
Thanks in advance
