(SES + SDK15)
Hi!
I am trying to create an new firmware prototype based on ble_app_template_sample
Until now I have a connectable firmware, with one service and several characteristics. Everything is working well.
But now I have the need to change the advertisement manuf data on the fly while advertising.
It seems that in SDK 15 the way the manuf data is changed is different.
Until now I haven't succeeded on this.
Is there any ble peripheral connectable sample that also updates manuf data using SDK15 new approach?
I have this prototype code:
//Some globals
BLE_ADVERTISING_DEF(m_advertising); /**< Advertising module instance. */
ble_advertising_init_t
ble_advdata_manuf_data_t manuf_data; //Variable to hold manufacturer specific data
void advertising_init(void)
{
ret_code_t err_code;
memset(&init, 0, sizeof(init));
//just to...
data[0] = 0xCA;
data[1] = 0xCA;
data[2] = 0xCA;
data[3] = 0xCA;
data[4] = 0xCA;
data[5] = 0xCA;
data[6] = 0xCA;
data[7] = 0xCA;
manuf_data.company_identifier = 0xFFFF;
manuf_data.data.p_data = data;
manuf_data.data.size = sizeof(data);
init.advdata.p_manuf_specific_data = &manuf_data;
init.advdata.name_type = BLE_ADVDATA_SHORT_NAME; // Use a shortened name
init.advdata.short_name_len = 6;
init.advdata.include_appearance = true;
init.advdata.flags = BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE;
int8_t tx_power = -4;
init.advdata.p_tx_power_level = &tx_power;
init.config.ble_adv_fast_enabled = true;
init.config.ble_adv_fast_interval = APP_ADV_INTERVAL;
init.config.ble_adv_fast_timeout = APP_ADV_DURATION;
init.evt_handler = on_adv_evt;
err_code = ble_advertising_init(&m_advertising, &init);
APP_ERROR_CHECK(err_code);
ble_advertising_conn_cfg_tag_set(&m_advertising, APP_BLE_CONN_CFG_TAG);
}
Then, in an app timer I have this starting code:
static void timer_timeout_handler(void * p_context)
{
UNUSED_PARAMETER(p_context);
//Reset to avoid double buffering
ret_code_t ret = sd_ble_gap_adv_set_configure(m_advertising.adv_handle,NULL,NULL);
//???
ret = sd_ble_gap_adv_set_configure(m_advertising.adv_handle,m_advertising.p_adv_data,NULL);
VERIFY_SUCCESS(ret);
}
Please, how to change one or two sample bytes of advertising frame in the //??? place?
Thanks al lot
Alex
