Unable to find the DFU service while using ble_app_buttonless_dfu example provided in SDK17.

Hi,

I am unable to find the DFU services in example ble_app_buttonless_dfu provided in SDK 17.

Please suggest how to proceed.

Thanks 

Raj

Hi Raj,

The DFU service is included in the ble_app_buttonless_dfu example (you will see many reference to it if you search for "dfu" in main.c), and you will see the device advertising with the DFU UUID if running the example on a DK. Note that it requires bootloader etc, so it requires a bit to et up unless you flash a merged hex file that included everything. Just to see how this shoud work you could flash for instance <SDK>\examples\dfu\secure_dfu_test_images\ble\nrf52832\sd_s132_bootloader_buttonless_with_setting_page_dfu_secure_ble_debug_without_bonds.hex if working with the nRF52 DK.

If this does not address the issue, then please elaborate/clarify so that I can answer more specifically.

Hi Einar,

Now I am able to put my board(nrf52840) in DFU mode with buttonless code using Esp32 as controller.

The problem currently i am facing is to send a init packet to my nrf board at data point.

when ever i am trying to send an init packet, I didn't get any reply at my ESP32 board  and after some time my nrf board comes in application mode from DFU mode.

For reference i am attaching logs of my ESP32 board

20:44:35.188 ->

when i am trying to send init packet as show in log above nothing happens.

i stored the content of init packet in a local buffer in my code as shown below 

uint8_t emgPkt3[144] = {0x12,0x8D,0x01,0x0A,0x47,0x08,0x01,0x12,0x43,0x08,0x01,0x10,0x34,0x1A,0x05,0xCA,0x01,0xFE,0x95,0x03,0x20,0x20,0x28,0x20,0x30,0x20,0x38,0xF0,0xA2,0x03,0x42,0x24,0x08,0x03,0x12,0x20,0x65,0x2B,0xCB,0x9A,0xCA,0x79,0xC4,0x5C,0x99,0x81,0x98,0x06,0xF3,0x1E,0x3D,0x27,0xA7,0x08,0x69,0x20,0x20,0x94,0x51,0x7F,0x4B,0xD0,0x14,0x53,0x74,0x55,0x53,0xEF,0x48,0x01,0x52,0x040,0x80,0x01,0x12,0x20,0x10,0x20,0x1A,0x40,0x7B,0x14,0x2F,0xA8,0x3B,0xAA,0xB2,0x4B,0x84,0x5C,0x44,0x59,0xBF,0x05,0x24,0x5A,0xBF,0xDF,0x44,0x24,0x1F,0xC5,0xAE,0x3C,0xF6,0x5C,0x54,0xD0,0x3E,0x84,0xDB,0x04,0xD4,0x8B,0xA6,0x3B,0x64,0xE4,0x30,0x5E,0x8E,0x01,0xEB,0x47,0xDE,0x69,0x79,0x27,0x93,0x09,0xF3,0xE1,0xE2,0xF1,0x1B,0x73,0xE2,0x19,0x6B,0x2F,0xAB,0x1A,0x11,0x0E};

and sending four bytes at a time till all 144 bytes are completed.

can you suggest me where i am wrong?

Thanks

So I need to Create data object after every 4kb transfer of firmware image ?

[Einar Thorsrud]

Yes, that is correct. If you have not allready, then it may be good to look at an existing implementation to see the flow (such as nrfutil, perhaps starting at send_firmware() for this specific topic).

[rajAsthana]

Hi Einar,

As you suggest after every 4kb of firmware transfer, I created a data object,

Firmware sent flow 

DFU Controller  ----------0x06 0x02----------->  DFU Target (AT DFU characteristics)

DFU Controller  <----------60 06 01 00 10 00 00 00 00 00 00 00 00 00 00 00-----------  DFU Target 

DFU Controller  ----------01 02 00 10 00 00---------->  DFU Target (AT Control characteristics)

DFU Controller  <----------60 01 01---------- DFU Target 

DFU Controller  ----------Send firmware packet no response----------> DFU Target (AT data characteristics size 4kb)

DFU Controller  ----------01 02 00 10 00 00---------> DFU Target (AT Control characteristics)

DFU Controller  <----------60 01 01---------- DFU Target 

DFU Controller  ----------Send next 4kb firmware packet no response---------> DFU Target (AT Control characteristics next size 4kb)

process repeat until all packets are transferred.

But the problem here is my firmware update crashed after sending first 4kb of firmaware packet .

Here is the log from Secure bootloader

Hi Raj,

I do not really see much indication of a problem in the log before you have some log lines I assume you added about the app_timer and then the bootloader is initialized, probably after a reset. I cannot see why though, but it could be the inactivity timeout? How long have you configured it, and is there a decent amount of time with no activity before the reset?

Hi Einar,

Finally performed  DFU OTA of my Nordic Board with your support.

Thanks a lot Bro hope we have a discussion on another topic very soon.

Thanks

Raj
