Is this a mistake? The description states that if called twice the last set of parameters is what isen-USTelligent Community 13Tue, 08 Dec 2020 13:46:23 GMThttps://devzone.nordicsemi.com/thread/283830?ContentTypeID=1Tue, 08 Dec 2020 13:46:23 GMT137ad170-7792-4731-bb38-c0d22fbe4515:98bac6a3-d11a-45e0-be2c-0823988283d8brianreinhold<p>I think the answer to this is that one can only use part of the&nbsp;ble_cfg_t struct to set the GAP, GATT, etc. parameters since it turns out to be a union. Therefore one uses repeat calls to the same method with an id explaining which of the union options is being used.
