Can I change BLE_GAP_ROLE from center to peripheral after ble_enable in S120?

[YeLun]

I want to star advertising after scan start then stop in S120. Or, wait the S130?

Thanks!

You cant do that on S120 after you have chosen the role by using ble_enable devzone.nordicsemi.com/.../

But on S130 which is already available now, you can use both central and peripheral roles concurrently. You dont even have to switch role, just don't use the role you do not need.
