NRF_SDH_BLE_OBSERVER Why Not Run

[MapleBay]

It appears that "NRF_SDH_BLE_OBSERVER" will not be run. Why?

Hi

NRF_SDH_BLE_OBSERVER is a macro and not a function that is run, what exactly is your issue here as the ble_stack_init() functionshould be running fine by default in the ble_app_hrs_rscs_relay app.

Hi, Simon

I wanted to port my old pc-ble driver program to SDK17, but now there are problems, I was able to initialize successfully. The code is look like

uint32_t ble_stack_init()
{
  uint32_t err_code;

  uint32_t ram_start = 0;
  err_code = nrf_sdh_enable_request();
  BLE_USB_PRINT_MSG_NUM("NRF SDH Enabel Request Error Code = 0x", err_code, 1);
  // err_code = nrf_sdh_ble_default_cfg_set(1, &ram_start);
  err_code = nrf_sdh_ble_app_ram_start_get(&ram_start);
  BLE_USB_PRINT_MSG_NUM("NRF SDH APP Ram Start Get Error Code = 0x", err_code, 1);
  err_code = ble_cfg_set(m_config_id, ram_start);
  BLE_USB_PRINT_MSG_NUM("BLE CFG Set Error Code = 0x", err_code, 1);
  err_code = nrf_sdh_ble_enable(&ram_start);
  BLE_USB_PRINT_MSG_NUM("BLE Enable Error Code = 0x", err_code, 1);

  switch (err_code)
  {
  case NRF_SUCCESS:
    break;
  case NRF_ERROR_INVALID_STATE:
    usb_printf_len("BLE stack already enabled\n", 16);
    break;
  default:
    BLE_USB_PRINT_MSG_NUM("Failed to enable BLE stack. Error code: 0x", err_code, 1);
    break;
  }
  NRF_SDH_BLE_OBSERVER(m_ble_observer, APP_BLE_OBSERVER_PRIO, ble_evt_dispatch, NULL);
  return err_code;
}

When I want to connect a device or do something else that generates a BLE event, my entire application will be rebooted. I checked that it did not enter my event handler (ble_evt_dispatch).

So I'm confused. Don't have any ideas to solve this problem.

Best regards,
