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.
As my previous reply show, I made some small modifications to Set_AdvData(), SysTick_Handler(), and main().
In Set_AdvData() I've added sd_ble_gap_adv_stop(m_adv_handle); at the top, because you can't modify your advertising buffer while you are advertising. And I've added a advertising_start(); at the end of Set_AdvData() to start advertising again.
In SysTick_Handler() I set your timer to 5 seconds instead of 5 ms.
In main() I modified your if(g_setAdvData) sentence.
The modified code:
//Propaganda
uint8_t Propaganda = 0;
static void Set_AdvData()
{
sd_ble_gap_adv_stop(m_adv_handle);
ret_code_t err_code;
ble_advdata_t advdata;
uint8_t flags = BLE_GAP_ADV_FLAG_BR_EDR_NOT_SUPPORTED;
ble_advdata_manuf_data_t manuf_specific_data;
manuf_specific_data.company_identifier = APP_COMPANY_IDENTIFIER;
// Prepare the scan response manufacturer specific data packet
ble_advdata_manuf_data_t manuf_data_response;
uint8_t data_response[] = {0x08,0x00,0x03,0x08,0x00,0x03,0x08,0x00,0x03};
//Change Data Advertising..
++Propaganda;
data_response[0]=Propaganda;
data_response[1]=Propaganda;
data_response[2]=Propaganda;
data_response[3]=Propaganda;
data_response[4]=Propaganda;
data_response[5]=Propaganda;
data_response[6]=Propaganda;
data_response[7]=Propaganda;
data_response[8]=Propaganda;
data_response[9]=Propaganda;
manuf_specific_data.company_identifier = 0x0059;
manuf_specific_data.data.p_data = data_response;
manuf_specific_data.data.size = sizeof(data_response);
// Build and set advertising data.
memset(&advdata, 0, sizeof(advdata));
advdata.name_type = BLE_ADVDATA_NO_NAME;
advdata.flags = flags;
advdata.p_manuf_specific_data = &manuf_specific_data;
// Initialize advertising parameters (used when starting advertising).
memset(&m_adv_params, 0, sizeof(m_adv_params));
err_code = ble_advdata_encode(&advdata, m_adv_data.adv_data.p_data, &m_adv_data.adv_data.len);
APP_ERROR_CHECK(err_code);
advertising_start();
}
#define SYSTICK_COUNT_ENABLE 1
#define SYSTICK_INTERRUPT_ENABLE 2
uint32_t msTicks = 0; /* Variable to store millisecond ticks */
/* SysTick interrupt Handler. */
void SysTick_Handler(void) {
if(++msTicks == 5000) {
LEDS_INVERT(BSP_LED_1_MASK); /* light LED 2 very 1 second */
g_setAdvData = true;
msTicks = 0;
}
}
int main(void)
{
// Initialize.
log_init();

power_management_init();
ble_stack_init();

// Start execution.
NRF_LOG_INFO("Beacon example started.");
advertising_start();
uint32_t returnCode;
returnCode = SysTick_Config(SystemCoreClock / 1000);
// Enter main loop.
for (;; )
{
if(g_setAdvData) {
sd_ble_gap_adv_stop(m_adv_handle);
advertising_init();
advertising_start();
//Set_AdvData();
g_setAdvData = false;
}
idle_state_handle();
}
}
Hope this helps you.

Hi Andreas
Two questions!
1) Getting error
undefined ble_advertising_init(); not exist, i am using SDK 15.2.0
2) and why you commented my Set_AdvData() ?
//Set_AdvData();
This way wont update my advertising counter :(
Hi again.
I apologize for any confusion I've caused, I assumed you used SDK 15.0, and I also had some help solving your issue, and I missed a crucial point regarding what that solution did with your function Set_AdvData().
The solution i was gives uses advertising_init() to update your advertising counter instead of your Set_AdvData() function.
static void advertising_init(void)
{
uint32_t err_code;
ble_advdata_t advdata;
uint8_t flags = BLE_GAP_ADV_FLAG_BR_EDR_NOT_SUPPORTED;
ble_advdata_manuf_data_t manuf_specific_data;
manuf_specific_data.company_identifier = APP_COMPANY_IDENTIFIER;
manuf_specific_data.data.p_data = (uint8_t *) m_beacon_info;
if (g_setAdvData)
{
manuf_specific_data.data.p_data[3] = 0xED;
}
manuf_specific_data.data.size = APP_BEACON_INFO_LENGTH;
// Build and set advertising data.
memset(&advdata, 0, sizeof(advdata));
advdata.name_type = BLE_ADVDATA_NO_NAME;
advdata.flags = flags;
advdata.p_manuf_specific_data = &manuf_specific_data;
// Initialize advertising parameters (used when starting advertising).
memset(&m_adv_params, 0, sizeof(m_adv_params));
m_adv_params.properties.type = BLE_GAP_ADV_TYPE_NONCONNECTABLE_NONSCANNABLE_UNDIRECTED;
m_adv_params.p_peer_addr = NULL; // Undirected advertisement.
m_adv_params.filter_policy = BLE_GAP_ADV_FP_ANY;
m_adv_params.interval = NON_CONNECTABLE_ADV_INTERVAL;
m_adv_params.duration = 0; // Never time out.
err_code = ble_advdata_encode(&advdata, m_adv_data.adv_data.p_data, &m_adv_data.adv_data.len);
ble_advertising_init();
APP_ERROR_CHECK(err_code);
err_code = sd_ble_gap_adv_set_configure(&m_adv_handle, &m_adv_data, &m_adv_params);
APP_ERROR_CHECK(err_code);
}
Thats why it's commented out.
Just remove the ble_advertising_init(); I'm unsure how that code snip found its way into the code.

Sorry, i hadnt seen that you had change the advertising_init() to accept my Propaganda variable!
Thanks
It´s working! Thanks!
Btw, i had to put
uint32_t msTicks = 0; /* Variable to store millisecond ticks */
/* SysTick interrupt Handler. */
void SysTick_Handler(void) {
if(++msTicks >5) {
LEDS_INVERT(BSP_LED_1_MASK); /* light LED 2 very 1 second */
g_setAdvData = true;
msTicks = 0;
}
}
To trigger interrupt each 1 second...is that right ?
Hi.
Try:
uint32_t msTicks = 0; /* Variable to store millisecond ticks */
/* SysTick interrupt Handler. */
void SysTick_Handler(void) {
if(++msTicks == 1000) {
LEDS_INVERT(BSP_LED_1_MASK); /* light LED 2 very 1 second */
g_setAdvData = true;
msTicks = 0;
}
}
msTicks is milliseconds, so you need to set the if sentence equal to 1000 ms (which is 1 second)
