The maximum speed at which the switch happens depends very much on the environment, the distance at which the modules are placed and the type of Adv and connection methods used.
It is not possible to switch 4 times within 15 mS most of the times. Sometimes, if the Disconnection Pacet from the central gets lost, the peripheral will still stay in the connected state, till supervision timeout happens (minimum supervision timeout is 100 mS). On an average, switching from one device to another takes place in 50 mS.
You may wait for the launch of PSoC 6 BLE Device which supports 4 connections at a time. It is likely to be launched by the middle of next quarter.

thanks, then I have to wait and hope for a price near to the one of the PRoC. So my first solution with one cable based transmitter for 4 joysticks was the right way to start. As 4 players are rare I could try it with two receivers and cable-less joysticks.
