Thank you for your kind response. If it is possible to disable CCA, it'd be interesting to see what happened. I set AR_DIAG_IGNORE_CS bit but it doesn't work. If it is impossible to disable CCA, I want to do it with pseudo way like increasing threshold. But I couldn't find the way. Let me know, please.
