DOUBT IN OTA -DFU WITH BUTTON AND BUTTONLESS

[NANDHU]

HI

•  We are developing a 2d-3d  mouse .
•  We are trying to implement OTA-DFU into our  custom board .
•  We first tried it on development kit and its working fine too . I can able to update the "ble_app_hids_mouse" into our DK using nRF Toolbox mobile app.
•  We are using    "nRF5_SDK_14.2.0_17b948a".

I WILL EXPLAIN THE PROCEDURES I DID FOR IMPLEMENTING THE OTA -DFU

• First i flashed the softdevice hex file to the DK.(s132_nrf52_5.0.0_softdevice.hex).
• Then i flashed the bootloader hex with needed modification into the DK. (secure_dfu_ble_s132_pca10040_debug.hex).
• Then LED1 and LED3  in DK will light up the device will enter into DFU mode by advertising as "DfuTrag".
• Then using my android phone i uploaded the zip package containing the  application (ble_app_hids_mouse) hex file ,during  upload the LED2 and LED3 in the DK will turn on.
• After successful upload the DK can use as a mouse by pressing the buttons.

MY DOUBTS

1. When DK in DFU mode LED1 and LED3  will turn on, I checked the bootloader code but i didn't saw any function  to turn on the LED1 can you help to find in which c file or function LED1 was turning on . I saw the function to turn on the LED3 (inside leds_init())but i didn't findout the function to turn on LED1.
2. Similarly during the upload is takeing place LED2 AND LED3 will turn on ,but i didn't saw any function  to turn on the LED2 please help to find in which c file or function LED2 was turning on .

 THIS IS BOOTLOADER CODE WE ARE USEING

nRF5_SDK_14.2.0_17b948a->nRF5_SDK_14.2.0_17b948a->examples->dfu->bootloader_secure_ble->pca10040_debug->ses.

PLEASE ANSWER TO MY 1 AND 2. IF YOU CAN POSSIBLE MAKE SCREENSHOT WHERE ITS TURNING ON  LED1 AND LED2 AND SEND TO ME.

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.

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

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

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 .

1. I  flashed the softdevice first to DK.
2. Then i flashed the bootloader to DK.
3. 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 thanks a lot .

when i increased the RAM size its getting.
