The central decides what device it wants to connect to.

It normally uses the content of the advertisment to do this, for example the UUID.

It can search for a specific UUID, and then send a connect request to the device that sent an advertisment with this UUID.

This is done in the ble_app_hrc_c example in SDK. Have a look at how the BLE_GAP_EVT_ADV_REPORT in on_ble_evt() is handled. When it receives an advertisment with the heart rate service UUID it will try to connect to that device.

You need to clarify your question. Let me try to re-phrase it.

You need to connect 1 central to one peripheral, the grouping of peripheral and central is based on a UUID (For example, 0x08) , a peripheral with UUID 0x11 is not allowed to connect to a central with UUID 0x08.

Is my understanding correct ?
