I am not sure what you are trying to achieve.

My guess is that you want to advertise with m_beacon_info1[6] equal to 0x00 by default and when a button is pressed you want to send 10 advertising packets with m_beacon_info1[6] equal to 0xff before going back to the default advertising data.

I took a look at your code, and there are some faults. This won't work:

for(i=0;i<10;i++)
{
    err_code = sd_ble_gap_adv_start(m_adv_handle, APP_BLE_CONN_CFG_TAG);
    NRF_LOG_INFO("Beacon.");
}

Running sd_ble_gap_adv_start() two times (or more) in a row will not work. If you look at the explanatory text for sd_ble_gap_adv_start() inside ble_gap.h, you will see that the function returns NRF_ERROR_INVALID_STATE if you run it twice in a row.

If you want to send a specific amount of advertising packets I would recommend you implement it in this manner:

When the button is pushed you stop the advertising, update the advertising data (m_beacon_info1[6] equal to 0xff) and start the advertising again
Then you Start a timer
- In order to send out x amount of advertising packets, you have to configure the duration of the timer based on the advertising interval
When the timer expires you stop the advertising, update the advertising data (m_beacon_info1[6] equal to 0x00) and start the advertising again

Hi simon,

yes you are correct. Thanks for your quick reply

1) First two points , it works fine.

2) 3rd point is my problem. i cant see the advertising packets as m_beacon_info1[6] is 0xff in nrf connect app.

how should i send 10 advertising packets with m_beacon_info1[6] is 0xff?

how should i count advertising ?

3) Immediately the packets changed as m_beacon_info1[6] to 0x00.

Here i tried

if(flag==1) interrupt handler
{
ret_code_t err_code;
err_code = sd_ble_gap_adv_stop(m_adv_handle);
// nrf_drv_gpiote_out_toggle(14);
device_name_get();
advertising_init1();
uint32_t i;
err_code = sd_ble_gap_adv_start(m_adv_handle, APP_BLE_CONN_CFG_TAG);
NRF_LOG_INFO("Beacon.");

for(i=0;i>100;i++)
{
//i=0;
idle_state_handle();
i++;
}
advertising_init();
// nrf_drv_gpiote_out_toggle(14);
flag=0;
}

I will make sure I understand you correctly before I proceed.

You start advertising with m_beacon_info1[6]=0x00
A button is pressed, and m_beacon_info1[6] is set to 0xff
Then the device sends out 10 advertising packets and m_beacon_info1[6] is 0xff
- Have you confirmed that the advertising packet contains this value, by using a sniffer or similar?
When the next advertising packet is sent out, m_beacon_info1[6] is equal to 0x00
- Have you confirmed that the advertising packet contains this value, by using a sniffer or similar?

Do I understand you correctly?

Best regards,

Simon
