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.

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

1. 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?

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.

Thanks a lot . If there is any issue ,i will text you.

How can i increase the RAM allocated to the SoftDevice?

[Amanda Hsieh]

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.
