Works fine here on nRF Connect SDK v2.2.0 and on a nRF52833-DK.

Hi,

You mean Periodic Advertising? There is a sample for that in Zephyr.

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/samples/bluetooth/periodic_adv/README.html

1. I tried your reference its build and flash successfully

2. But in serial terminal getting Failed to create advertising set (err -5)

3. I will attach image of serial terminal please look on it

Just update the data back to the 1st data, when the timer_handler() triggers again

1. As of now am getting 1st data for 20 seconds ( i gave 20 sec sleep )

2. Second data ( updated data ) getting after 20 seconds ( After 20 seconds sleep ) and advertising

here is my query

1. After getting second data ( updated one ) again need to advertise 1st data

2. Need to do that one in a loop until my beacon off

What do you mean by "advertise periodically" ?

Hi,

Thank you for giving reference to me

1. But i need to do modification in beacon code itself if possible

2. Is there any way we can modify beacon code and advertise periodically like using loop concepts

Hi,

1. First things its worked really well and thank you for that as of now its advtizing only one time

2. but if i need to advtize periodically then which way is better to if i create while loop inside bt_ready function it will work but i tried in my case its not working

3. Is there any suggestions to advitze data periodically

Hi,

It need to be more like this:

static struct k_timer my_timer;

static void timer_handler(struct k_timer *timer)
{
	ARG_UNUSED(timer);
	bt_le_adv_update_data()

}


k_timer_init(&my_timer, timer_handler, NULL);
k_timer_start(&my_timer, K_MSEC(10000), K_MSEC(10000));

And then try calling k_timer_init and k_timer_start , after bt_le_adv_start()

Hi Sigurd,

1. I Followed Your snippet but getting some error

2. As well am attaching code and error screenshots please look on it

Here is some snippets:

static struct k_timer my_timer;

static void timer_handler(struct k_timer *timer)
{
	ARG_UNUSED(timer);

}


k_timer_init(&my_timer, timer_handler, NULL);
k_timer_start(&my_timer, K_MSEC(DURATION), K_NO_WAIT);

Then in timer_handler(), you call bt_le_adv_update_data()

Hi Sigurd,

Could you provide exact kernel timer api where i can pass bt_le_adv_update_data thats helpfull for me

Hi,

[quote user="Tharak"]I tried that one but my requirement is i need to update data without flashing [/quote]

Yeah, that's no problem.

Use e.g. a kernel timer , https://docs.zephyrproject.org/apidoc/latest/group__timer__apis.html , and in the timer callback use bt_le_adv_update_data to switch between hello and hii

Hi Sigurd,

I tried that one but my requirement is i need to update data without flashing

1. First 10 sec for example need to advtize hello

2. Next 10 sec need to update from hello to hii

Hi,

You can simply use the bt_le_adv_update_data() for this.
