how to reduce 3 peripheral to 1 peripheral in S130

[hana]

I'm using a S130 on nrf51822.

connect to 3 peripherals (in case of the master) connect to 1 central (in case of the slave)

But, I want to use 1 peripheral and 1 centeral How can I reduce 3 peripherals to 1 peripheral on central source? I can't find the definition. Please let me know that.

You want to do this to reduce the amount of RAM the SoftDevice needs? What SDK and SoftDevice version are you using?
