I'm glad it worked!

Best regards,

Thanks alot for your reply.

I've changed the RAM start adders from 0x20001720 to 0x20002068 and it solved the problem.

Hi!

Error code 4;
NRF_ERROR_NO_MEM - No memory for operation.

From the documentation:
"BLE stack initialization: A SoftDevice must be enabled with the required configuration parameters before it can be used. The default stack configuration can be customized with sd_ble_cfg_set before the SoftDevice is enabled. Most examples in the SDK use the default configuration with some modifications. When adapting an example, all of the default values may be overwritten. However, remember that changes might alter the size of the BLE stack RAM, which will change the application's start RAM address. If you provide an incorrect RAM start address when calling nrf_sdh_ble_enable, the function returns an error along with the new correct RAM start address. "

Have you tried changing the RAM start address?

Best regards,
Joakim

Hello,

After more debugging, I found that function nrf_sdh_ble_enable() returns error code =4.

static void ble_stack_init(void)
{
    ret_code_t err_code;

  
  /*
   * Before the delay was added, nrf_sdh_enable_request() got stuck
   */
  delay();
  
    err_code = nrf_sdh_enable_request();
    APP_ERROR_CHECK(err_code);

    // Configure the BLE stack using the default settings.
    // Fetch the start address of the application RAM.
    uint32_t ram_start = 0;
    err_code = nrf_sdh_ble_default_cfg_set(APP_BLE_CONN_CFG_TAG, &ram_start);
    APP_ERROR_CHECK(err_code);

    // Enable BLE stack.
    err_code = nrf_sdh_ble_enable(&ram_start);
    APP_ERROR_CHECK(err_code);

    // Register a handler for BLE events.
    NRF_SDH_BLE_OBSERVER(m_ble_observer, APP_BLE_OBSERVER_PRIO, ble_evt_handler, NULL);
}

Here is the contents of the configuration file in my project:

/*###ICF### Section handled by ICF editor, don't touch! ****/
/*-Editor annotation file-*/
/* IcfEditorFile="$TOOLKIT_DIR$\config\ide\IcfEditor\cortex_v1_0.xml" */

define block CSTACK    with alignment = 8, size = __ICFEDIT_size_cstack__   { };
define block HEAP      with alignment = 8, size = __ICFEDIT_size_heap__     { };

initialize by copy { readwrite };
do not initialize  { section .noinit };

keep { section .intvec };
place at address mem:__ICFEDIT_intvec_start__ { readonly section .intvec };
place in ROM_region   { readonly };
place in RAM_region   { readwrite,
                        block CSTACK,
                        block HEAP };

The SW calls NVIC_SystemReset() which is in app_error_fault_handler().

Please help.
