Buttonless DFU with bond not working

Hi,

I'm struggling to get Buttonless DFU with bond enabled working.

Setup details:

1) SDK 14.2

2) DK board - nrf52832

3) nrfconnect app on Android phone (8.0) :

DFU settings = Pkts receipt notification procedure : ON

Number of packets : 10

MBR : 4096

Keep bond information: ON

External MCU DFU : OFF

4) Custom app with bond enabled, BLE_GAP_ADDR_TYPE_RANDOM_STATIC(C1:C1:C1:C1:C1:C1), MITM enabled,

Followed the steps to generate bootloader keys and everything seems to be fine. Flashed SD, BL, APP onto DK board and I can see the app running.

Connected nrfconnect to my custom app, paired succesfully. I can see secure DFU service with Secure buttonless DFU.

After enabling the indication, I write value "0x01" and send to switch to DFU mode. I see device moved to DFU mode but with BD addr = EA:F8:73:D2:B8:CC.

Connected nrfconnect to DfuTarg and if I try to DFU, I think device switches to my custom app and I don't see DFU happening any more.

I'm wondering what would be wrong and I believe encryption fails due to different BD address used in DFU and app mode. What am I missing?

Tried looking into Nordic blogs, dev support but could not move forward. Also, I tried to see the DFU NRF log but I don't see any log messages

All I see on power ON is

<info> µ˜°: Setting vector table to bootloader: 0x00066000
<info> µ˜°: Setting vector table to main app: 0x00023000
<info> µ˜°: Record ID:    0x0001
<info> µ˜°: File ID:    0xF020
<info> µ˜°: Record key:    0x7010

I did used \nRF5_SDK_14.2.0_17b948a\examples\dfu\bootloader_secure_ble\pca10040_debug\armgcc\Makefile with logger enabled and optimization is -O0 in makefile. I'm not sure DFU logger does not show up in RTT viewer.

Attached are the config,make files for reference.

Your help is highly appreciated.

  • I did tested Buttonless DFU without bond and it works like charm.

  • The full Log messages in app while moving to DFU mode are below

  • Hi,

    By default, the SoftDevice will use DEVICEADDR[0] and (half of) DEVICEADDR[1] as the MAC address. This will be used by both the bootloader and application unless you explicitly set some other address. If you set another address in your application (why?), then you must do so in the bootloader as well.

    The example without bond sharing however, does not rely on having the same address. In fact, it needs to have a different address and will therefore typically be the default mac address (from  DEVICEADDR) incremented by one.

  • Hi,

    >> If you set another address in your application (why?), 

    To have unique address for different products. After doing as per your suggestion, I could progress little bit but now I get dfu error "Remote DFU error: INVALID OBJECT". I believe it is for Execute Opcode i.e. dfu_decode_commmand() returning false. I see log message in the dfu code as "Handler: Invalid protocol buffer stream". Not sure what I'm missing.

    Attached log file captured.

    Appreciate your help

  • Hello,

    Einar is out of office, so I will handle your case.

     

    Having the same address for all products seems a bit strange, as it may cause some issues separating several devices if there are multiple devices in the same area. The standard way of doing this is to use the DEVICEADDR[0] and DEVICEADDR[1], and use the advertising data to find the device that you are looking for.

     

    INVALID OBJECT usually means that the DFU packet is not accepted. How did you generate your DFU packet? Did you set the correct HW version, SD-version and application version? Note that the application version has to be incremented by at least 1 from the application that is currently running. So if you already uploaded the packet, you need to create a new DFU packet with application-version += 1 for the bootloader to accept it.

     

    Best regards,

    Edvin
