SDK 15.3 DFU with Bonds

[testsweng]

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

Hi,

Could you verify that the bootloader is compiled with the NRF_DFU_BLE_REQUIRES_BONDS option enabled in sdk_config.h? The bootloader will not support bond forwarding otherwise. 

By the way, the issue mentioned in the thread you linked to is fixed in SDK 16.0.0

[testsweng]

Please close this as I am too busy to get back to it.  It will be a few months before i need to try it again.  Thanks

[Vidar Berg]

No problem. Just let me know when you're ready to revisit this issue.

Hi, 

Can i continue here with the issue? I am facing something similar and to your question, bootloader does compile but it does not advertise at all unless i disable the bond forwarding support in it. 

Also, here is something i am having trouble with in SDK 15.3 --> https://devzone.nordicsemi.com/f/nordic-q-a/55705/application-service-uuid-gone-after-secure-ota-dfu
