how to use esp_ble_gatts_close ?

[datluong]

Hi all,
Currently, I want to terminate the connection between esp32 and mobile application by pressing a button.
How can I do that?
I have checked and then found this function:

Code: [Select all] [Expand/Collapse]

1. esp_ble_gatts_close(gatts_if, conn_id);

But I don't know how to implemet this function into my code, where can I find those two parameters, gatts_if and conn_id.
I used example code in example gatt_security_server in esp-idf folder.
Thank you very much,

When succesfully connected you will receive `ESP_GATTS_CONNECT_EVT`:

Hi,

You can find those values at gatts_profile_event_handler.

case ESP_GATTS_CONNECT_EVT:
spp_conn_id = p_data->connect.conn_id;
spp_gatts_if = gatts_if;
