Stop Advertising on nrf52832

I've found a workaround.

I was using sd_ble_gap_adv_stop(m_advertising.adv_handle) inside a timer handler which had a return type of void while sd_ble_gap_adv_stop has a return type of uint32_t, so I just adjusted that and now it's stopping advertising and not showing the error.

Since app_timer_create was complaining about the uint32_t type I just called a function inside it to match the types.

//handler
void test_handler(void *p_context){

advertising_stop();

}
//advertising_stop
uint32_t advertising_stop(void)
{

uint32_t ret_error2;
ret_error2=sd_ble_gap_adv_stop(m_advertising.adv_handle);
APP_ERROR_CHECK(ret_error2);
NRF_LOG_INFO("ADV. Stopped");

}

Try this:

sd_ble_gap_adv_stop(m_advertising.adv_handle);

If it returns 8(NRF_ERROR_INVALID_STATE) it means that, from the documentation:

"Invalid state to perform operation (most probably not in advertising state)."

I double checked it and the library is included and BLE_ADVERTISING_ENABLED is properly enabled.

The BLE_ADVERTISING_DEF is defined at ble_advertising.h. Can you help me check again that: the ble_advertising.h is included your project? If not please add this library and in sdk_config.h file, please certainly the BLE_ADVERTISING_ENABLED sets 1.

Oh, thank You! I've been looking at the documentation you provided and it says that the parameter adv_handle is "The advertising handle that should stop advertising.".I've tried to set this parameter as the same I used in my Advertising start function, but now I'm getting the error: ERROR 8 [NRF_ERROR_INVALID_STATE] .

On advertising start I'm using an instance defined by BLE_ADVERTISING_DEF, but I realized that the instance create doesn't have a adv_handle on it.How can I know if I'm defining the proper instance and treat this error?

As for your suggestion, from what I understood that would be a timed event to stop advertising right? Is it possible to stop it after a particular condition is met?

In my application i'm trying to stop the advertising after a certain variable is set, this would be like after pressing a button or something similar. Thanks in advance for your time.

I think you can look around this document which shows how to use Advertising on BLE. Moreover, if you want to stop advertising, you can do like this.

- You have to generate the event with interval delay after sd_ble_gap_adv_start is called then try to call sd_ble_gap_adv_stop after calling sd_ble_gap_adv_start and waiting for time with timer.
