sd_ble_uuid_vs_add () returns err_code = 16 (#define NRF_ERROR_INVALID_ADDR (NRF_ERROR_BASE_NUM + 16) ///< Bad Memory Address)

[Anesh]

Hi, I am using nRF52832 with S132 softdevice and SDK version 11. I am getting bad memory address error code.

err_code = sd_ble_uuid_vs_add (&base_uuid, &ble_service->uuid_type);
if (err_code != NRF_SUCCESS){
SEGGER_RTT_printf(0, "err_code: %d \n", err_code);
return err_code;
}

Can anybody help me to figure out what could be the reason for such errors? Thank!

My best guesses would be that one or both of the parameters to sd_ble_uuid_vs_add is either NULL, or it is not 4 byte aligned. Easy enough to tell if you add the addresses to your SEGGER printf.

Thanks John for the comment, I defined base uuid like this

 #define BLE_UUID_BASE_UUID            		{0x5B, 0xB3, 0x03, 0x64, 0x0C, 0x16, 0x5D, 0x8A, 0x1B, 0x48, 0x84, 0x63, 0x00, 0x00, 0x1F, 0xC0} // 128-bit base UUID

then in service.c file,

ble_uuid128_t base_uuid = {BLE_UUID_BASE_UUID};

When printed out uuid_type

SEGGER_RTT_printf(0, "uuid_type: %d \n", ble_service->uuid_type); 

I got uuid_type 0, it means invalid UUID type.

#define BLE_UUID_TYPE_UNKNOWN       0x00 /**< Invalid UUID type. */

What else could you guess? Do you need any more info? Thank you very much for your time.

Easy enough to tell if you add the addresses to your SEGGER printf What do you mean by this, base_uuid? or the address where this base uuid is getting stored

[John]

I was thinking you could show the two addresses being passed to sd_ble_uuid_vs_add like this:

SEGGER_RTT_printf(0, "base_uuid addr = %x, ble_service addr = %x\n", &base_uuid, &ble_service);

Okay, hey I want to bring one more info, that may help you to understand the problem. I am not able to step into gap_params_init();. main() look likes this

ble_stack_init();
  device_manager_init(true);
  gap_params_init();
  services_init();
  advertising_init();
  conn_params_init();
  // Start execution.
  err_code = ble_advertising_start(BLE_ADV_MODE_FAST);
  APP_ERROR_CHECK(err_code);

and gap_params_init()

static void gap_params_init(void)
{
    uint32_t                err_code;
    ble_gap_conn_params_t   gap_conn_params;  	        // Struct to store GAP connection parameters like max min connection interval etc
    ble_gap_conn_sec_mode_t sec_mode;     		// Struct to store security parameters

    BLE_GAP_CONN_SEC_MODE_SET_OPEN(&sec_mode);

    // Store the device name and security mode in the SoftDevice. Our name is defined to "HelloWorld" in the beginning of this file
    err_code = sd_ble_gap_device_name_set(&sec_mode,
                                          (const uint8_t *)DEVICE_NAME,
                                          strlen(DEVICE_NAME));
    APP_ERROR_CHECK(err_code); // Check for errors

    // Always initialize all fields in structs to zero or you might get unexpected behaviour
    memset(&gap_conn_params, 0, sizeof(gap_conn_params));

    // Populate the GAP connection parameter struct
    gap_conn_params.min_conn_interval = MIN_CONN_INTERVAL;
    gap_conn_params.max_conn_interval = MAX_CONN_INTERVAL;
    gap_conn_params.slave_latency     = SLAVE_LATENCY;
    gap_conn_params.conn_sup_timeout  = CONN_SUP_TIMEOUT;

    // Set GAP Peripheral Preferred Connection Parameters
    // The device use these prefered values when negotiating connection terms with another device
    err_code = sd_ble_gap_ppcp_set(&gap_conn_params);
    APP_ERROR_CHECK(err_code);
                                          
    // Set appearence                     
    sd_ble_gap_appearance_set(0);
    APP_ERROR_CHECK(err_code);                                          
}

As you asked in your last comment base_uuid address is 20002FBC. I can't tell you ble_service_uuid because I can't reach to that part of code, debugger stopped.
