There is no need to switch. You can be central and peripheral at the same time. We have an experiemental example for the S130 in our latest SDK, v9.0.0, check out examples\ble_central_and_peripheral\experimental\ble_app_hrs_rscs_relay

The S130 SoftDevice supports concurrent Central and Peripheral role. You don't need to switch.

Device A can be connected to one central(tablet) as a peripheral, and three peripherals(B,C,D) as a central.
Then B or C must disconnect from A. Lets say B. B must to start advertise, and C must start to scan. When they enter connection, B will be the peripheral and C will be the central. Diffucult to say how much time the operation will take, depends on the advertising interval and scan window.

You could also have a setup where A(central) is connected to B(peripheral), B(central) is connected to C(peripheral) and C(central) is connect to A(peripheral).
