Both the AP models are supported on 220.127.116.11.250 version.
Please make sure you have configured on of the discovery methods.
1. DHCP option 43 on DHCP server.
2. DNS entry with controller's control IP address.
3. Manually point the AP to controller using below command.
set scg ip xxx.xxx.xxx.xxx (where xxx.xxx.xxx.xxx is controller's control plane IP address)
Also check and make sure APs are currently on standalone version and support SCG (you can check if SCG is supported or not, by running "gets scg" command on AP CLI)
4. Use auto-discovery. Put the APs and the SmartZone on the same subnet and power up. They will auto-discover and register with the controller. Once the APs are registered with the SZ, you can move them to different subnets if needed.
And like Omer said - ensure that the APs have been factory reset and that they're running standalone code (104.x.x.x.x to 114.x.x.x.x).
Also, ensure that lwapp2scg is enabled on the smartzone:
Auto discovery is done over LWAP, which is by default disabled on SZ controller (if not enabled during the initial setup wizard).
If you want to use LWAP discovery (L2) then you have to login into controller CLI and enable it.
