Under some conditions I want to force advertising to transition from slow to fast. With SDK 14, I could just call ble_advertising_start(&m_advertising, BLE_ADV_MODE_FAST), but with SDK 15, that returns NRF_ERROR_INVALID_STATE.
I see that there are some other support cases from people trying to change the advertising data, getting an invalid state error apparently because they have to change to a new buffer or something. I'm not trying to change any of the advertising data, just change from slow back to fast advertising. Is there something I can do to avoid the dreaded invalid state error?
