Calling sd_ble_gap_adv_stop() does not emit an on_adv_evt event

[Boaz]

I'm a bit at a loss of how to voluntarily stop advertising:
My related thread says I should call sd_ble_gap_adv_stop(), but when I do, no corresponding event is raised by the soft-device. This ultimately means that on_adv_evt() in main.c does not get called, the static m_adv_mode_current in ble_advertising.c does not change state to BLE_ADV_MODE_IDLE, and the ble_advertising module in an unmatching state.

How can I overcome this? Is the only way to reliably stop advertising is to wait for it to time-out?

Version: nRF5 SDK 11.0.0, s132, with PCA10040 EVB

The Advertising Module can be used for many typical "Connectable Advertising" scenarios, but if you want other functionality you are free to modify it, or not use it at all.

You can set the advertising data with ble_advdata_set(), and then call sd_ble_gap_adv_start() with the parameters you like. Maybe you want to advertise forever, and always stop it manually with sd_ble_gap_adv_stop()?

Good answer! Its easy to forget that I can opt to not to use the advertising module at all. Cheers :)

Hi Petter,

if i want use both manually stop advertising and timeout stop advertising, how can i menage it? Because if i stopped manually the advertising, after start the timeout that send a IDLE_EVT_ADV and give an error ( obviously) because it is stopped preciously. thanks, Anna

@annapalu Then you will have to modify the Advertising Module. Maybe it is easier to use the sd_* API directly?

So do you think, that is better use only the command sd_ble_gap_adv_stop? Is there not a method to stopped the timeout to avoid that a new advertising_stop is called? thanks, Anna

I don't know what is better, I don't know what your application is. If you only want to start one type of advertising and stop it either with sd_ble_gap_adv_stop() or on timeout this is very simple to implement. Have you tried?
