nRF52840 add custom service

[Fengjie]

Hello everyone, i have get nRF52840-PDK and now working on it. I use SDK 13 and SoftDevice S140. My Project base on ble_app_template and i want add my service in this Project.

I follow this Tutorial BLE Services, a beginner's tutorial

First declare a service structure

        typedef struct BLEMyServiceTag
{
uint16_t conn_handle;
uint16_t service_handle;
ble_gatts_char_handles_t char_handle;} BLEMyService;


BLEMyService BMA250E_service;

in the function services_init() in main.c initialize the service

BMA250E_service_init(&BMA250E_service);

Following code are the function BMA250E_service_init()，

void BMA250E_service_init(BLEMyService *p_service)
{
uint32_t err_code1;
ble_uuid_t	service_uuid;
ble_uuid128_t base_uuid	=	BLE_UUID_BIL_BASE_UUID;
service_uuid.uuid	=	BLE_UUID_OUR_SERVICE;


err_code1		=	sd_ble_uuid_vs_add(&base_uuid,&service_uuid.type);	
APP_ERROR_CHECK(err_code1);

err_code1		=	sd_ble_gatts_service_add(BLE_GATTS_SRVC_TYPE_PRIMARY,&service_uuid,&p_service->service_handle);
APP_ERROR_CHECK(err_code1);}

Compile, download code to nRF52840-PDK, but it doesn't work. The board can't advertising. I test my code in nRF51 DK and it works.

Where did i wrong? Can anyone help me?

/******************************Problem solved******************************************/

I am getting an error "No Memory for operation"(err code=4) when sd_ble_uuid_vs_add() is called. Reading the similar Questions in Nordic Dev Zone, i change the following code from ble_stack_init() in main.c.

default: ble_cfg.common_cfg.vs_uuid_cfg.vs_uuid_count = 0;

changed: ble_cfg.common_cfg.vs_uuid_cfg.vs_uuid_count = BLE_UUID_VS_COUNT_DEFAULT;

and then I get the same error "No Memory for operation"(err code=4) when softdevice_enable() is called.

I changed the IRAM1 Start and Size and this problem solved.

Have you completed all the sections marked /* YOUR_JOB: .. */ in the template source code? Only then you can expect application to work.

i have tested my code in nRF52840 PDK with Project ble_app_uart,experimental_ble_app_blinky. It works, and a new Service is added. But it can't work with ble_app_template.

[Fengjie]

my code can work with nRF5_SDK_13.0.0-1.alpha_055eef3, but can't work with nRF5_SDK_13.0.0_04a0bfd. very strange.

Then you probably need to do full diff between all files you use in the project with SDK v13.0.0-1.alpha and v13.0.0. You can also approach it from MAP file (and other compilation/linking products) and see which module/function changed.

Hello,

The simple way is to check all the err_code to know where the board reset.
