hi Abian could provide full example of this tree function

i am suing softdevce 112 on nrf52801 rigago mudule

sd_ble_gap_adv_stop(missing param)

SVCALL(SD_BLE_GAP_ADV_STOP, uint32_t, sd_ble_gap_adv_stop(uint8_t adv_handle));

where in the code m_adv_data and adv_param ?

sd_ble_gap_adv_set_configure(&m_adv_handle, &m_adv_data, &adv_params);

sd_ble_gap_adv_start(missing param )

Hi all,

I solved this issue with the following steps:

1)You must to call the sd_ble_gap_adv_stop() function.

2)Then you would change any config data as you want using for example sd_ble_gap_adv_set_configure(&m_adv_handle, &m_adv_data, &adv_params);

3) And finally, you must to call sd_ble_gap_adv_start() function to initialize the BLE.

All of this is used in SDK 15.0.

Thanks

Abian.

sorry , i didn't get you .can you share me briefly

Then use

ble_advertising_restart_without_whitelist(m_advertising);

after calling my function to update the advertisement data

bluetooth_update_name("DEVICE 123");

This should work.

thank you ,i dono know whether you understood my question, may be my communication problem . I am explaining it again, we are using custom board nrf52832 , i will connect the device using nrf toolbox app ,and then i will give command as for example '1' , when i receive '1' , it should stop advertise and then it should re advertise with the new name which i was given in the condition

if(command=='1')

{

change_name;

stop_adv;

start_adv;

}

similar to this it should work

Thanks&Regards

Hi pspavi

There is sadly no direct solution for the NRF Toolbox's standard firmware to do this.
A first step is to check out whether you a ready to setup and build your own custom "Nordic UART Service" (NUS) firmware to do this.

I have written my own multi-service application including multi-protocol support and non-volatile configuration, which I cannot share for confidentiality reasons.

Yet the code mentioned before is the crucial part to change a device's name. My suggestion for you is to adapt your main.c code to include my logic to control the ble_advertising_init_t related parts with your own defined NUS command.

Have a look inside \examples\ble_peripheral\ble_app_uart or \examples\ble_peripheral\experimental\ble_app_cli in the SDK to see how to scaffold your own NUS application. It gave me the crucial starting point to do more complex setups.

Also see Command Line Interface library for how to add a custom command.

Hi....atok ..sorry for late , i didn't receive your notification . yes i want to change my device name after bonding periodically via nrf toolbox ,how to do that ? i tried all the ways and read many threads , i don't know how to Re- initialize the advertising again ... can you share me sample code so that i can , it will be more helpfull

Thanks&Regards

Hi venu gopal

I found myself in the situation to implement a dynamically updating device name. Here some working, user-friendly code. The idea is to reuse the ble_advertising_init_t struct from initialization:

#include "nrf_sdh_ble.h"


BLE_ADVERTISING_DEF(m_advertising);
static ble_advertising_init_t adv_init;

/* This function will update the device name and advertising data accordingly. */
void bluetooth_update_name(uint8_t* name) {
	ret_code_t err_code;
	ble_gap_conn_sec_mode_t sec_mode;

	BLE_GAP_CONN_SEC_MODE_SET_ENC_NO_MITM(&sec_mode);

	if (current_config.name[0] != '\0') {
		err_code = sd_ble_gap_device_name_set(&sec_mode, name, strnlen(name, 10));
		APP_ERROR_CHECK(err_code);
	}
	else {
		err_code = sd_ble_gap_device_name_set(&sec_mode, (const uint8_t *)NUS_DEVICE_NAME, strlen(NUS_DEVICE_NAME));
		APP_ERROR_CHECK(err_code);
	}


  //sd_ble_gap_adv_stop(&m_advertising.adv_handle);

	err_code = ble_advdata_encode(&adv_init.advdata, m_advertising.enc_advdata, &m_advertising.adv_data.adv_data.len);
	VERIFY_SUCCESS(err_code);

	if (m_advertising.adv_modes_config.ble_adv_extended_enabled == true)
	{
#ifdef BLE_GAP_ADV_SET_DATA_SIZE_EXTENDED_CONNECTABLE_MAX_SUPPORTED
		m_advertising.adv_data.scan_rsp_data.len = BLE_GAP_ADV_SET_DATA_SIZE_EXTENDED_CONNECTABLE_MAX_SUPPORTED;
#else
		m_advertising.adv_data.scan_rsp_data.len = BLE_GAP_ADV_SET_DATA_SIZE_MAX;
#endif // BLE_GAP_ADV_SET_DATA_SIZE_EXTENDED_CONNECTABLE_MAX_SUPPORTED
	}
	else
	{
		m_advertising.adv_data.scan_rsp_data.len = BLE_GAP_ADV_SET_DATA_SIZE_MAX;
	}

	err_code = ble_advdata_encode(&adv_init.srdata,
		m_advertising.adv_data.scan_rsp_data.p_data,
		&m_advertising.adv_data.scan_rsp_data.len);

	sd_ble_gap_adv_set_configure(&m_advertising.adv_handle,
		m_advertising.p_adv_data,
		NULL);
}


/* This is my initialization routine for advertising */
static void advertising_init(void) {
	uint32_t err_code;

	memset(&adv_init, 0, sizeof(adv_init));

	adv_init.advdata.name_type = BLE_ADVDATA_FULL_NAME;
	adv_init.advdata.include_appearance = false;
	adv_init.advdata.flags = BLE_GAP_ADV_FLAGS_LE_ONLY_LIMITED_DISC_MODE;

	adv_init.srdata.uuids_complete.uuid_cnt = sizeof(m_adv_uuids) / sizeof(m_adv_uuids[0]);
	adv_init.srdata.uuids_complete.p_uuids = m_adv_uuids;

	adv_init.config.ble_adv_fast_enabled = true;
	adv_init.config.ble_adv_fast_interval = APP_ADV_INTERVAL;
	adv_init.config.ble_adv_fast_timeout = APP_ADV_DURATION;

	adv_init.evt_handler = on_adv_evt;

	err_code = ble_advertising_init(&m_advertising, &adv_init);
	APP_ERROR_CHECK(err_code);

	ble_advertising_conn_cfg_tag_set(&m_advertising, APP_BLE_CONN_CFG_TAG);
}

If you have some questions, please ask right away 🙂

Hi Arya,

You will need to call sd_ble_gap_adv_stop() after you have changed the name with sd_ble_gap_device_name_set().

See this thread for more info.

RE: Device Name Change

Arya — Thu, 02 May 2019 13:01:51 GMT

Hi Martin,

Can you elaborate a little bit about the APIs to use to disable, re-initialize, and start advertising again? I am actually trying to do the same but unable to find the error?

RE: Device Name Change

MartinBL — Mon, 02 Jul 2018 13:56:02 GMT

Hi,

When you use sd_ble_gap_device_name_set() you actually only update the name in the device name characteristic in the Generic Access service. To change the name being advertised as well, you will need to disable, re-initialize, and start advertising again, after you have changed the characteristic with sd_ble_gap_device_name_set().

Hi Andy

I checked all those threads.

All are for previous SDK 14, 13, 12.

When i tried to implement in SDK 15.0 I it is unsuccessfull.

Here i have attached my main.c file.

Please check and give some suggestion.

If you have any example code in SDK 15.0 please share.

Then you need to change the advertisement data. There are lots of threads about that already.

Hi Andy

I need to change the DEVICE NAME.

In my application i need to change the device name automatically after it got disconnected from the phone(ble uart connection)

RE: Device Name Change

Andy — Sat, 30 Jun 2018 13:10:19 GMT

Why do you need to do that? Do you need to change the device name or the advertisement data?
