Function esp_idf_sys::esp_ble_gap_set_security_param

pub unsafe extern "C" fn esp_ble_gap_set_security_param(
    param_type: esp_ble_sm_param_t,
    value: *mut c_void,
    len: u8,
) -> esp_err_t

@brief Set a GAP security parameter value. Overrides the default value.

               Secure connection is highly recommended to avoid some major
               vulnerabilities like 'Impersonation in the Pin Pairing Protocol'
               (CVE-2020-26555) and 'Authentication of the LE Legacy Pairing
               Protocol'.

               To accept only `secure connection mode`, it is necessary do as following:

               1. Set bit `ESP_LE_AUTH_REQ_SC_ONLY` (`param_type` is
               `ESP_BLE_SM_AUTHEN_REQ_MODE`), bit `ESP_LE_AUTH_BOND` and bit
               `ESP_LE_AUTH_REQ_MITM` is optional as required.

               2. Set to `ESP_BLE_ONLY_ACCEPT_SPECIFIED_AUTH_ENABLE` (`param_type` is
               `ESP_BLE_SM_ONLY_ACCEPT_SPECIFIED_SEC_AUTH`).

@param[in] param_type : the type of the param which to be set @param[in] value : the param value @param[in] len : the length of the param value

@return - ESP_OK : success - other : failed
