How to add DFU service with the custom service

Hello Vidar,

The issue is in "Queued Write Module" (service init function)

I have commented the qwr module in service init section, and set NRF_SDH_BLE_VS_UUID_COUNT = 2 in sdk_config.h file

/**@brief Function for initializing services that will be used by the application.
*/
static void services_init(void)
{
uint32_t err_code;
//nrf_ble_qwr_init_t qwr_init = {0};
ble_dfu_buttonless_init_t dfus_init = {0};

// Initialize Queued Write Module.
// qwr_init.error_handler = nrf_qwr_error_handler;

// err_code = nrf_ble_qwr_init(&m_qwr, &qwr_init);
// APP_ERROR_CHECK(err_code);

dfus_init.evt_handler = ble_dfu_evt_handler;

err_code = ble_dfu_buttonless_init(&dfus_init);
APP_ERROR_CHECK(err_code);

tps_init();
cus_init();
}

After this code is working properly and in app also i can access custom service.

Didn't find what is the cause .

but Fortunately issue is solved .

is this related to nrf_log?

I have set these parameters

and i have set -> NRF_FPRINTF_FLAG_AUTOMATIC_CR_ON_LF_ENABLED 0

Thanks for you support and valuable response.

Regards,

Rohit

You may need to increase the RAM base address for your app when you increase the Softdevice UUID buffer. Have you enabled debug logging? It should tell if that's the case.

I suggest that you enable debug logging over UART or RTT so you can see the debug messages if you haven't done it already. Also, add 'DEBUG' to the list of pre-processor definitions in order to get a verbose crashlog.

Maybe increase NRF_SDH_BLE_VS_UUID_COUNT in you sdk_config header. It needs to correspond with the number of 128-bits base UUIDs you have in your app. The DFU service use 1.

I don't see any references to 'DFU' in the code you uploaded. You can use the Buttonless DFU template example as a reference for integrating it into your app. Also recommend taking a look at this guide if you haven't done it already: https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/getting-started-with-nordics-secure-dfu-bootloader
