i tried app timer..i re initialized parameter (advertising_init_new(); ) holds after changing the (advertising_init();).....

I would rather recommend that you setup a timer (app_timer can be used - see application timer tutorial) that change the advertising back after n times the advertising interval.

Thanks for your valuable recommend. i changed to interrupt handler as you said

for (;;)
{
//advertising_start();
idle_state_handle();
if(flag==1)
{
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_init_new(); // reinitialised beacon parameteruint32_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;
}

[quote userid="14926" url="~/f/nordic-q-a/46230/change-beacon-advertising-parameters-while-button-pressed/183187"]What do you mean by this? [/quote]

i mean that, after pressing button,the next 10 advertising will be re initialed advertising (advertising_init_new(); ).then it back to normal advertising mode.

now i checked in NRFconnect app..i can see the re initialed advertising value by 1sec. then it changed immediately.i want to check advertising count. how do i check advertising count?

What do you mean by this?

It is not recommended to spend long time inside interrupt handlers, I would recommend that you do the work in main loop and use flags that you set in the handlers, to tell what should happen in main context.

hi jorgen ,

void in_pin_handler(nrf_drv_gpiote_pin_t pin, nrf_gpiote_polarity_t action)
{
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(); // Re_initialise the parameter
uint16_t i;
err_code = sd_ble_gap_adv_start(m_adv_handle, APP_BLE_CONN_CFG_TAG);
NRF_LOG_INFO("Beacon.");
nrf_delay_ms(1000);
advertising_init(); // after 10 advertising set to back to normal
}

All r works fine.

Except one thing.

while pressing button,i reinitialized advertising data (advertising_init1();).

then next 10 advertising the parameters should hold and then its back to its original condition(advertising_init();)

i stuck in 10 advertising. please help me

If you want advertising data to change, you need to call the functions that initialize advertising data again. It is not sufficient to change the variable that was used when first initializing advertising data. The data is copied to internal buffers in the stack.

Hi Jorgan,,

Please reply me asap..

i tried interrupt while pressing button i changed beacon parameters, but i checked in my app,the value should changed.

But Led works as button pressed.

void in_pin_handler(nrf_drv_gpiote_pin_t pin, nrf_gpiote_polarity_t action)
{
ret_code_t err_code;

nrf_drv_gpiote_out_toggle(14);
m_beacon_info1[6]=0xff;

NRF_LOG_INFO("Beacon.");

}

Should i add anything in in_pin_handler?

There is a tutorial explaining how to use the button handling library in this GitHub repository.

hi jorgen

how can i change my code to attain my result? waiting for your reply

hi jorgen,

would you have any example program for button interrupts?

RE: change Beacon advertising parameters while button pressed?

Jørgen Holmefjord — Tue, 16 Apr 2019 13:42:02 GMT

If you want the advertising data to change on button press, you need to implement GPIOTE/app_button to get interrupts whenever the button is pressed, and then update the advertising data in the handler.

You are not doing this in your code, so it will not change after startup.

yes ,i can check button input status in advertising_init(). and i called once in the function.

You are only changing this variable inside advertising_init(), and you only call this function once. Are you seeing the change if you hold the button before powering the device?

RE: change Beacon advertising parameters while button pressed?

hi Jorgen,

Thanks for ur reply,

while pressing button,the beacon parameters changed from m_beacon_info1[6]=0x00; to 0xFF. Next 10 advertisement the value should not changed.Then it continues to value 0x00..the button acts as an alarm.

While debugging the value should changed from 00 to FF..But in running condition still remains it same..

Hi,

[quote user=""]I m not getting the result[/quote]

What result do you expect to get, and what result do you actually get? Should the advertising only change while you hold the button, or should it stay changed after you release the button as well?

Best regards,
Jørgen
