I guess you're correct. See this migration guide.

Dear Sir,

Thank you for your reply.

But in SDK15 this function is not available in ble_gap.h, I think.

Please correct me if I am wrong.

My mistake, sorry. It's available in ble_gap.h.

Hi, Thank you for your reply. I think the fuction "sd_ble_gap_adv_data_set()" is not avaialble in SDK15. I could not find the function declaration in the file (ble_advdata.h.) you specified.Please confirm it and let me know if I am wrong.

That function is available by including ble_advdata.h. About the location, that depends on your application of course. Given the fact that you're using a timer to update the battery level, I guess that you're continuously advertising? You could try calling the function in the timeout of your battery update (be sure to check the return of the function). If you're only advertise for a certain moment and then stop, you could call the function just be fore you restart advertising.

Hi, Thank you for your response.

But is this function"sd_ble_gap_adv_data_set()" available in SDK15?..

I am a little confused about the locatin at which the functions to be called..

If possible please provide the main.c file for the same.

Thanking you in advance.

In my application I add so called "Manufacturer Specific Data" to the advertising packet to store status information like the battery level. You can add this data during initialization of the advertising:

ble_advertising_init_t init;
memset(&init, 0, sizeof(init));

ble_advdata_manuf_data_t manuf_data;    //Variable to hold manufacturer specific data
manuf_data.company_identifier = 0xFFFF; // See https://www.bluetooth.com/specifications/assigned-numbers/company-identifiers
manuf_data.data.p_data        = &m_adv_data[APP_ADV_STATUS_IDX];
manuf_data.data.size          = 6; // Or whatever size your data has.
init.advdata.p_manuf_specific_data = &manuf_data;

You can then update the advertising data by manipulating the manufacturing data:

ret_code_t err_code = sd_ble_gap_adv_data_set( m_adv_data, sizeof(m_adv_data), NULL, 0 );
