About this example
https://github.com/NordicPlayground/nrf51-ble-tutorial-advertising
It´s advertising the data
uint8_t data_response[] = "Many_bytes_of_data" with the MAC and RSSI
without connection.
How can advertising dynamic data without connection ?
For example, MAC, RSSI + some dynamic data ?
Is there some SES example ?
Thanks
Hi.
You can do this by using two data buffers, so that you avoid re-using an active buffer, because that is not allowed by sd_ble_gap_adv_set_configure().
If you use SDK 15.2, you can take a look at ble_advertising_advdata_update(), which can be used to update the advertising data. The update will be effective even if the advertising has already been started.
ret_code_t ble_advertising_advdata_update(ble_advertising_t * const p_advertising,
ble_gap_adv_data_t * const p_new_advdata_buf,
bool permanent)
{
if (permanent)
{
memcpy(&p_advertising->adv_data, p_new_advdata_buf, sizeof(p_advertising->adv_data));
p_advertising->p_adv_data = &p_advertising->adv_data;
}
else
{
p_advertising->p_adv_data = p_new_advdata_buf;
}
return sd_ble_gap_adv_set_configure(&p_advertising->adv_handle,
p_advertising->p_adv_data,
NULL);
}
If permanent is set to true, the advertising data will be permanently updated inside the module. Otherwise, the previous advertising data will be restored when there is a transition to the next advertising mode.

thanks for fast reply
in my code advertising_init() i can successfully advertising manufacturer data_response[]
but in
static void Set_AdvData()
{
ret_code_t ret_code;
static ble_gap_adv_data_t new_data;
ret_code = ble_advertising_advdata_update(&m_advertising, &new_data, true);
}
wich are the parameters to me update the data_response[] ?
static void advertising_init(void)

Could you help me ? After a while, the software stop to make advertising...can you give me some tip ?

Hope this helps.

Andreas, i guess that was mobile APP side problem! I changed to Adafruity scanner and now i am successfully receiveing the advertsing...without stops...
I was using the Nordic Ble Scanner, but after a while, stop to receive advertising... i guess that is some app setup that is wrong...
But, please, see if my Set_AdvData() is right!
