sd130 and sdk12.1.0 ble bootloader problem

[air]

I'm sorry. I closed this question and can't reopen. I need more answer. If I solve all problem I'll close this question.

As you mentioned I'll try HW version modification. And I'll add the result.

Hello,

I have some problem in DFU. I ask this again. I did as below.

1. private key generation nrfutil keys generate c:\vault\priv.pem

2. public key generation in code format nrfutil keys display --key pk --format hex c:\vault\priv.pem nrfutil keys display --key pk --format code c:\vault\priv.pem nrfutil keys display --key pk --format code c:\vault\priv.pem --out_file dfu_public_key.c

3. experimental_ble_app_buttonless_dfu project compile and package file make nrfutil pkg generate --hw-version 1 --sd-req 0x87 --application-version 4 --application nrf51422_xxac.hex --key-file key.pem app_dfu_package.zip

4. bootloader_secure compile with dfu_public_key.c(made in process 2) and bootloader setting file make nrfutil settings generate --family NRF51--application nrf51422_xxac.hex --application-version 3 --bootloader-version 2 --bl-settings-version 1 settings.hex

5. merge bootloader and settings hex file mergehex -m nrf51422_xxac_s130 settings.hex -o output_file.hex

6. SD130 / output_file.hex program into PCA10028 Board after erase all

7. I try DFU in android phone. I can see DfuTarg. But, It fails to DFU app_dfu_package.zip(made in process 3).

What’s wrong? I don’t know.

**I want DFU process as below.

1. my application run when power on
2. bootloader enter(using buttonless_dfu projecs - Already I merged with my application.) after some key input (This key is in my custom board.)
3. upload my new F/W using bootloader_secure in android phone.
4. my new application run again after DFU done.**

I need your help eagerly.

Thanks, I saw the DFU works after doing as you mentioned(set the --hw-version to 51 and not 1).

Now, How should I modify buttonless_dfu projecs If I want to do as below?

1. my application run when power on
2. bootloader enter(using buttonless_dfu projecs , Already I merged with my application.) after some key input (This key is in my custom board.)

int main(void)

{

uint32_t err_code;

UART_TX_HIGH;

lfclk_config();								// clock init
nrf_delay_ms(5);

twi_master_init();							// eeprom init
TWI_400K;									// twi frequency

// dfu check
if(checkDfu())								// check eeprom and enter into DFU mode
	goto DFU;
	.
	.
	.
// ******* main loop start ******* //
while (1)
{
	.
	.
	.
}

DFU:

startDfu();

}

// It's the same as buttonless_dfu main function

void startDfu(void)

{

uint32_t err_code;
bool erase_bonds;

// Initialize.
err_code = NRF_LOG_INIT(NULL);
APP_ERROR_CHECK(err_code);

timers_init();
buttons_leds_init(&erase_bonds);
ble_stack_init();

peer_manager_init(erase_bonds);
if (erase_bonds == true)
{
	NRF_LOG_DEBUG("Bonds erased!\r\n");
}

gap_params_init();
advertising_init();

services_init();
NRF_LOG_DEBUG("Services are initialized\r\n");

conn_params_init();
NRF_LOG_DEBUG("conn params are initialized\r\n");

// Start execution.
application_timers_start();
NRF_LOG_DEBUG("app timers are started\r\n");

err_code = ble_advertising_start(BLE_ADV_MODE_FAST);
APP_ERROR_CHECK(err_code);
NRF_LOG_DEBUG("advertising is started\r\n");

// loop
for( ; ; )
{
	if(NRF_LOG_PROCESS() == false)
	{
		power_manage();
	}
}

}

3. upload my new F/W using bootloader_secure in android phone.
4. my new application run again after DFU done.

To do this, I tried to modify DFU control point. But, it didn't work. I am trying to solve this problem. I'm sorry but it's better to have your help.
