Amanda i did all the thing you recommended except that increases in RAM allocated for softdevice .

There is no error in the code when i build it.

so i did the following things .

I flashed the softdevice first to DK.
Then i flashed the bootloader to DK.
Then using nRFtoolbox mobile app i uploaded the application zip file having the buttonless dfu feature and it uploaded sucessfully to DK. But the issues is application (ble_app_hids_mouse)is not advertising and working . i don't known why .

please reply as soon as possible .

Amanda i included the folder and file in the same way but its still showing the same error.

But when i included the path of this folder like in below screen shot then the error was gone

IS THIS A RIGHT WAY TO SOLVE THIS ISSUE?

please answer to my question

You can right-click on the project to create a new folder and add the nrf_dfu_svci.c into the libraries.

THANKS

Amanda ,when i looked the ble_app_buttonless_dfu code i saw another folder "nRF_SVC" includeing "nrf_dfu_svci.c" file . is i want to include this to ble_app_hids_mouse.

look below screen short.

Amanda i included the folder and c file to the code(ble_app_hids_mouse.) but now also the same issue is showing.

That is stated in the p_app_ram_start variable, or more correctly in the variable that p_app_ram_start points to, i.e. *p_app_ram_start . If you add p_app_ram_start to watch and then set a breakpoint after sd_ble_enable() you should be able to see which value points top_app_ram_start.

Take a look at this video, it explains how to modify the build settings, including the memory settings.

Also, see this post.

Hi NANDHU,

Add #include "nrf_pwr_mgmt.h" at the top of main.c

(Updated)

To initial services, you can start by copying the code from services_init() in the ble_app_buttonless_dfu to the services_init() function in ble_app_hids_mouse. Make sure you add the files in the nRF_DFU folder, i.e. ble_dfu.c, ble_dfu_bonded.c and ble_dfu_unbonded.c to the ble_app_hids_mouse example. Make sure that you change NRF_SDH_BLE_VS_UUID_COUNT to 2 in sdk_config.h as well as increase the RAM allocated to the SoftDevice.

Amanda ,

I downloaded a new SDK and trying to implement buttonless dfu service to the "ble_app_hids_mouse" .

The hardware we are using for test is only the development kit.(not our custom board).
we decided implement the buttonless dfu service first on DK.
ble example using to add buttonless secure dfu service is "ble_app_hids_mouse"

(C:\nordic_semi\nRF5_SDK_14.2.0_17b948a\nRF5_SDK_14.2.0_17b948a\examples\ble_peripheral\ble_app_hids_mouse\pca10040\s132\ses).

PROBLEMS

First i tryed to implement the power management module and i included to but its showing some warning .I will give its screen short below . please help me to overcome that warning.

changes i made in code screen short are below

I following the step by step procedures in the document given by you .if there is any error or warning getting during procedures i will inform you like these .Is it fine for you?

NANDHU — Mon, 05 Aug 2019 07:06:49 GMT

Actually there is no error is showing .I just flashed the modified "ble_app_hids_mouse" which support buttonless dfu to the our board but its not advertising . so i debugged it using JLink then i noticed that when code execution is entering to " "nrf_dfu_set_adv_name_init();" but its not leaving from these function .

i don't known why .

note:- i didn't flashed the bootloader hex to our board.

Hi,

[quote user="NANDHU NAKULAN"]But my code was execution was breaking ,when entering to the below function in services_init()[/quote]

What error message does nrf_dfu_set_adv_name_init() returen?

This post and this post might help you.

[quote user="NANDHU NAKULAN"]what is these "nrf_dfu_set_adv_name_init();" function doing[/quote]

It is answered in this post.

hi Amanda,

I added all requested changes to add the buttonless dfu service to "ble_app_hids_mouse".

But my code was execution was breaking ,when entering to the below function in services_init()

nrf_dfu_set_adv_name_init(); inside ble_dfu_buttonless_async_svci_init(void).

please help me to solve these issue,

Actually what is these "nrf_dfu_set_adv_name_init();" function doing

Hi,

Yes, you are right. Please let me correct that:

According to the sdk_config.h of "ble_app_hids_mouse", the POWER_ENABLED is 0.

To use nrf_pwr_mgmt_init() in the power_management_init, you have to enable the module as

// <e> NRF_PWR_MGMT_ENABLED - nrf_pwr_mgmt - Power management module
//==========================================================
#ifndef NRF_PWR_MGMT_ENABLED
#define NRF_PWR_MGMT_ENABLED 1
#endif

You also need to check nrf_pwr_mgmt.c is in the Libaries.

Amanda ,

In "ble_app_hids_mouse" i didn't find the functions calling for configure to use the power management module.

"power_management_init()" is not used in "ble_app_hids_mouse"
And also not used this"nrf_pwr_mgmt_run();" in "ble_app_hids_mouse".Then how you conform that all the power management module is configured in "ble_app_hids_mouse".

Hi,

[quote user="NANDHU NAKULAN"]Is the "ble_app_hids_mouse" application contains all those things ?[/quote]

Yes, you can compare the sdk_config.h.

NANDHU — Thu, 01 Aug 2019 14:17:09 GMT

Amanda ,

I verified the my doubt about bootloader.

MY NEXT DOUBT.

When i looked the documentation provided by you i noticed that for adding buttonless secure DFU service to a BLE application the application must uses "Peer Manager" and application must be configured to use the power management and also the application is responsible for initializing the BLE stack.

Is the "ble_app_hids_mouse" application contains all those things ?
Is there any thing wanted to add by us?

please answer to my first and second question as soon as you can possible.

One important doubt ,

Is the bootloader code using for both OTA-DFU with button and buttonless are same?

I think both needed separate bootloader code .because both bootloader advertising with separate names .

If you find difficult with our application please just tell me how to change the "ble_app_hids_mouse" application to a buttonless DFU -OTA supporting application.

I recommend you refer to the Buttonless DFU Template Application for a working code example. You can also find relevant documentation in the Buttonless Secure DFU Service documentation.

SORRY ONE CORRECTION I UPLOADED THE ZIP FILE OF APPLICATION USING nRF Connect NOT hex FILE

RE: DOUBT IN OTA -DFU WITH BUTTON AND BUTTONLESS

NANDHU — Thu, 01 Aug 2019 06:17:18 GMT

Hi ,

I think when we turn OFF the device and turn ON first the execution goes through the bootloader part and then goes through the application part.

I done the OTA-DFU update successfully using the bootloder with button (ieC:\nordic_semi\nRF5_SDK_14.2.0_17b948a\nRF5_SDK_14.2.0_17b948a\examples\dfu\bootloader_secure_ble\pca10040_debug\ses).
And also done the OTA -DFU on our custom board (ie our mouse) with the above bootloader code .But i changed the LED PINS and BOOTLODER BUTTON which is feasible to our custom board.The OTA-DFU done successfully using nRF Toolbox mobile app and with our custom board.If we hold the bootloader button while turning ON our custom board its going to the DFU mode too.

NOW I WANT TO DO THE BUTTONLESS OTA -DFU AND IMPLEMENT IT INTO OUR CUSTOM BOARD.

I gone through your documentation about Buttonless DFU Template Application and i done the buttonless OTA-DFU successfully on development kit .

I WILL EXPLAIN THE PROCEDURES I DID FOR BUTTONLESS OTA -DFU.

First i flashed the softdevice hex to the nRF52832 soc in the DK (....\nRF5_SDK_14.2.0_17b948a\nRF5_SDK_14.2.0_17b948a\examples\dfu\secure_dfu_test_images\ble\nrf52832\softdevice_s132.hex).
Then i flashed the bootloader hex to the DK.(....\nRF5_SDK_14.2.0_17b948a\nRF5_SDK_14.2.0_17b948a\examples\dfu\secure_dfu_test_images\ble\nrf52832\bootloader_secure_ble_debug_without_bonds_s132.hex).

NOW THE DEVICE (DK) WILL ADVERTISE AS "DfuTest"

Then using nRFConnect desktop app i connected to "DfuTest" and update the ble_app_buttonless_dfu application hex over the air sucessfully. (....\nRF5_SDK_14.2.0_17b948a\nRF5_SDK_14.2.0_17b948a\examples\dfu\secure_dfu_test_images\ble\nrf52832\ble_app_buttonless_dfu_with_bonds_s132_with_setting_page.hex).

NOW IT WILL ADVERTISE AS "Nordic_Buttonless"

Then using nRFConnect desktop app i connected to "Nordic_Buttonless" and update the same application hex again and its also done sucessfully.

MY DOUBTS

Where is the buttonless bootloader code in sdk. ( ie these "bootloader_secure_ble_debug_without_bonds_s132.hex "file code ).
I want to change our application code to buttonless DFU-OTA supporting application how can i did these .
If you find difficult with our application please just tell me how to change the "ble_app_hids_mouse" application to a buttonless DFU -OTA supporting application.

please answer to my doubts 1 2 and 3.

Hi NANDHU,

This Master boot record and bootloader section elaborated more detail.

The SoftDevice supports the use of a bootloader. A bootloader may be used to update the firmware on the SoC.

Hi Amanda ,

Thanks for the reply.

NEXT DOUBT

After OTA-DFU there is bootloader hex application hex and softdevice hex in our nRF52832 soc.If we turn OFF the DK and turn ON what will the order of execution of those hex file
i.e which hex file will execute first which one second .

Hi,

Please take a look at <nRF5_SDK_14.2.0_17b948a>\components\libraries\bootloader\ble_dfu\nrf_ble_dfu.c:

#define ADVERTISING_LED_PIN_NO              BSP_LED_0                                               /**< Is on when device is advertising. */
