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.

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. */
#define CONNECTED_LED_PIN_NO                BSP_LED_1                                               /**< Is on when device has connected. */

and trace ADVERTISING_LED_PIN_NO and CONNECTED_LED_PIN_NO variables.

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 .

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. 

[Amanda Hsieh]

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 

[NANDHU]

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.
