I would like to start advertising after BLE connection disconnected. But ble_advertising_start() return errCode 0x8.
static void ble_evt_handler(ble_evt_t const* pBleEvt, void* pContext)
{
switch (pBleEvt->header.evt_id)
{
case BLE_GAP_EVT_DISCONNECTED:
{
NRF_LOG_INFO("BLE_GAP_EVT_DISCONNECTED\n");
advertisingStart();
}
break;
...
}
...
}
The following is log message of nRF52832 device.
