Hmm... I assume that nrf_sdh_enable_request()/sd_softdevice_enable() is called successfully? Is the RAM start and size correct?

Is the vector table address updated with the correct start address of the application, ref sd_softdevice_vector_table_base_set()?

Double check the examples/guide:

as far as i understand ,i am using it :

uint8_t m_adv_handle = BLE_GAP_ADV_SET_HANDLE_NOT_SET; /**< Advertising handle used to identify an advertising set. */

or if you mean somthing else please explain

i am repeating my problem:

DFU work perfect and .

i have complete merge package with settings (secure boot loader ,application that works and software device + settings)

the tag works

when entering dfu with button if enters dfu i recognize if with your app and downloading new app the same one (packed in sip file like in the instruction) when it finish download the unit resets but when i am getting to :

err_code = sd_ble_gap_device_name_set(&sec_mode, new_name, DYNAMIC_NAME_LEN);
APP_ERROR_CHECK(err_code);

its not passing

what can be the reason and how to debug it

thank you

Hi,

The error code is BLE_ERROR_INVALID_ADV_HANDLE (0x3004).

Use BLE_GAP_ADV_SET_HANDLE_NOT_SET when requesting a new handle. For subsequent calls like adv_set_configure, tx_power_set, or device name changes, use a valid m_adv_handle returned earlier (e.g. '0').
