How to switch between connection handles when nrf52 is connected to multiple centrals?

Hi,

I am using nRF52 and SDK13 with SoftDevice 132 v 4.0.2 which is now supporting multi-peripheral connections. I am using multi-peripheral example for reference. In that i have connected 4 android devices to nRF52. I want to send data from nRF52 to each of connected device. So i think I need to switch between connection handles to send data..How to achieve this?
