CC3235MODSF: Cannot scan 5gh channel.

Part Number: CC3235MODSF
Other Parts Discussed in Thread: UNIFLASH

Hello,

Even though there are many APs with 5gh, they are not caught on the scan-list at all.

Below is the scan log for example and they are all 2.4gh.

I did not change any radio settings in code and uniflash.
