[advertising stop]

[annapalu]

Hi all,

Someone can give me a information about the difference between function uint32_t err_code = sd_ble_gap_adv_stop(); and stop the advertising with using the timeout that put the state machine to ADV_MODE_SLOW and after in IDLE_MODE when arrive the GAP_EVT_TIMEOUT ( i use a gls example).

Because i don't understand how when the a BLE_ADV_EVT_IDLE is send the advertising stopped. how Does work it?

If i use a sd_ble_gap_adv_stop, is there a way to stopped the EVT_TIMEOUT? Thanks, Anna

Hi sigurd,

sorry i have another question ( hope the last). If the advertising starts and my board connect to the phone. the BLE_GAP_TIMEOUT doesn't occurs or it occurs and the connection state ignore it. How can i understand this procedure? Thanks.

If your phone connects to the board, you will not get the BLE_GAP_TIMEOUT. Instead advertising is stopped by the softdevice, and you will get the event BLE_GAP_EVT_CONNECTED telling you that the phone has connected to the board.

Ok, this is clear. But the my idea(maybe is wrong) is that when i set the options, ble_adv_fast_timeout = 30; a timer starts and when expires send a BLE_GAP_TIMEOUT. When the connection occurs, this timers is stopped by softdevice and BLE_GAP_TIMOUT is not getting?

Yes, the timer is stopped. The timer will not expire or timeout, and therfore you dont get the BLE_GAP_TIMOUT.

Ok, perfect. i think that the softdevice stops the timer when connection occurs.Correct? And is there an api function to avoid that the timer will expire? Because sometimes i want to stop the advertising not using a state machine ADV_MODE_FAST --> BLE_ADV_MODE_IDLE, but using a advertising_stop() api function(for example when i press the bottom) and in this case i would that the timers don't occurs. Thanks, so much
