Hello all,
I need your help. Thanks so much.
I have master AP 3800 with version : 8.5.151.0
Another 3800 can join WLC, but 3700 can not join
OS for 3700 is: ap3g2-k9w8-tar.153-3.JPJ2.tar
Please see attached file for details logs.
Solved! Go to Solution.

The versions of the ME and AP do not match. For details, refer to the Deployment Guide.
https://www.cisco.com/c/en/us/td/docs/wireless/controller/technotes/8-5/b_cisco_mobility_express_8_5/b_cisco_mobility_express_8_5_chapter_0111.html#concept_4E1DCD5CC7A74E9FA52AF3B393D071D8
Upgrading the AP version directly is also an option.
If the Controller version is 8.5.151, the AP version should be 15.3 (3) JF10.
* Note that you should choose C3700 instead of AP3G2.

Download image failed, notify controller!!! From:17.1.1.29 to 0.0.0.0, FailureCode:3
The AP has joined a 9800 loaded with Amsterdam-17.1.1 and it is trying to go back to AeroOS.
That is why I'm asking to see directory contents to see if the AP still have an RCV folder or not.

Well, if the RCV folder is still available, then delete the all the CAPWAP folders and reboot the AP.
Because there is only one valid IOS left, the AP is guaranteed to boot into RCV.
WARNING: This is a 2700/3700 AP trying to join a controller running 8.5.X.X. There is a "feature" whereby the AP will download the firmware (from the controller) TWICE, reboot TWICE before the radios start serving clients. We call this behaviour as "double-download".

Thanks @Leo Laohoo !!! Below from 'dir' command. There is only one AireOS and no RCV folder. And I did reset twice, the same error.

Thanks, the output is very helpful.
This is the reason why the AP cannot download the firmware.
Issue the following commands:
debug capwap console cli delete /f /r flash:update
Reboot the AP and see if the AP can now download the firmware from the controller.

"update" is deleted from flash. But the same error. There might be no correct image from my Controller. Should I change AP image to "c3700-k9w8-tar.153-3.JF10.tar" as @HaifengLi 's advice, and upgrade directly instead of from Controller?

Sorry, no command "show ap bundle all". Only command "show ap packet-dumb"
AP0062.ec3c.6db4>show ap ?
packet-dump AP packet-dump commands
or
AP0062.ec3c.6db4#show ap ?
packet-dump AP packet-dump commands

Hi @Leo Laohoo and @HaifengLi ,
With "c3700-k9w8-tar.153-3.JF10.tar", all 3700 APs can join 3800 WLC. Thanks you all for very prompt support.

Hi @HaifengLi ,
I will ask my partner for 15.3 (3) JF10. Is the link below correct location for JF10:
https://software.cisco.com/download/home/285029867/type/280775090/release/15.3.3-JF10
Thanks.
