Currently, the WLC currently has 2702 AP already joined, but the 3802 will not join the WLC.
This is a Lab setup with basic config and no security enhancement like ACLs.
If someone who has worked on the 2504 or is very skilled in wireless can help me out, that would be very helpful.
WLC software: 8.5.171
WLC SWITCH CONFIG:
LAB-CORE#show run int gi1/0/37
interface GigabitEthernet1/0/37
switchport mode trunk
spanning-tree portfast trunk
AP SWITCH CONFIG:
interface GigabitEthernet1/0/1
switchport access vlan 103
switchport mode access
spanning-tree portfast edge

On a side note.
I have another post open for the same WLC where I am having issues with accessing the WLC from another network. If you work with WLC and know about the 2504 please take a look and see if you can help me out.

Factory reset the AP and try to join with a console cable on it just to see the logs. I´d say the problem may be on the Access Point as it seems that the join request is comming and the join response is being sending plus you already have access point on it.
On the switch, let the config for the access point port as simple as possible. Only switchport mode access and switchport access vlan 103

Agree with Flavio, also make sure you have enough license and on dhcp you don’t have option 60, vendor class identifier set for 2700 only.

This is a brand new AP out of a sealed box that I opened today.

I have access to just about every hardware possible due to the company I work for. I have added other AP 2702 and they all join so it's not a licence issue, also I know how to check for that.
I am mainly a route and switch guy but I have deployed vWLC, the old 2106 and recently for a customer a 9800 WLC. I am only having issues with this 2504 model.
