We have dug into the driver files and concluded that the CCA related values are likely = in the firmware or on the registers of the hardware. And please correct us if we are thinking wrong. We would appreciate the help if someone can give us some starting points, = such as the address of the register that stores the carrier sensing values (CCA values) = or the result of it (whether the carrier is busy or idle), to investigate. The chipset we are using is compex WLE900VX-7AA. We are currently using Ubuntu 14.04.03 with kernel version 4.1.5, = but we can use any versions of OS and kernel if they support 802.11ac bandwidth. Thank you for help in advance. ------------------------------- Seowoo Jang, Ph.D. Ubiquitous Network Laboratory EECS, Seoul National University CEL=A0=A0=A0+82-10-3723-3401 E-mail=A0swjang@netlab.snu.ac.kr ------------------------------- _______________________________________________ ath10k mailing list ath10k@lists.infradead.org http://lists.infradead.org/mailman/listinfo/ath10k
