Hi.

You have BSP_INDICATE_FATAL_ERROR state if LED1 and LED2 are on at the same time.

Can you try to build the debug version of the secure_bootloader?

You find it in the folder nRF5_SDK_15.2.0\examples\dfu\secure_bootloader\pca10040_ble_debug.

Do you use Segger Embedded Studio?

Best regards,

Andreas

Hi.

Sorry, the fault is mine, I should be clearer with my explanation.

1. Open the file pca10040.h in folder nRF5_SDK_15.0.0_a53641a\components\boards

2. Edit line 52 and 53 like this:

#define LED_START      17
#define LED_1          17

EDIT TO THIS:
#define LED_START      14
#define LED_1          14

And edit this on line 74:

#define BUTTON_2       14

EDIT TO THIS:
#define BUTTON_2       17

3. Save and close the pca10040.h file

4. Open the secure_bootloader project in the folder nRF5_SDK_15.0.0_a53641a\examples\dfu\secure_bootloader\pca10040_ble in the IDE you wish to use.

5. Compile the secure_bootloader project and flash this to your device. You also need to flash the SoftDevice (found in the folder nRF5_SDK_15.0.0_a53641a\components\softdevice\s132\hex)

thank you Andeas because of my poor english i can't understand what you said

do you mean i should compile C:\nRF5_SDK_15.0.0_a53641a\examples\dfu\secure_dfu_test_images\ble\nrf52832\sd_s132_bootloader_buttonless_with_setting_page_dfu_secure_ble_debug_without_bonds

? or other project using advertising

if you said first i don't know how to recompile hex file :(

Hi.

I suggest that you use a project then and edit the LED which shows when your device is advertising.

Open the file nRF5_SDK_15.0.0_a53641a\components\boards\pca10040.h, and edit the following on line 52 and 53:

#define LED_START      17
#define LED_1          17

EDIT TO THIS:
#define LED_START      14
#define LED_1          14

And edit this on line 74:

#define BUTTON_2       14

EDIT TO THIS:
#define BUTTON_2       17

Compile and download this .hex file to your device.

Does your LED blink now when it advertises?

(Some more information on custom boards)

i have a custom board without any buttons and i have two leds(pin numbers are 14 and 15) in my board

so i cannot observe led blink because this hex file is precompiled

but in my android phone i seldom found Nordic_Buttonless like this(bottom of list)

as you look this screenshot, signal is dead and after i click refresh Nordic_Buttonless disappear

i don't know how to solve it

thank you Andreas

Hi.

Is your board advertising? Does LED1 blink? Do you have a custom board?

Best regards,

Andreas

Hi thank you for reply i have one more question

after i follow this

something strange was happend

sometimes actually seldom i got Buttonless but most of all i couldn't found Buttoless

this are steps i followed

first i put this in cmd

nrfjprog --program C:\Users\mmsw\Desktop\cho\nRF5_15.2_ok_1s-p\examples\dfu\secure_dfu_test_images\ble\nrf52832\sd_s132_bootloader_buttonless_with_setting_page_dfu_secure_ble_debug_without_bonds.hex --chiperase

and second i put this because i have board without buttons

nrfjprog --reset

I don't know why i seldom find Buttonless in nrfconnect scanner list
