Topic of my work is building a prototype to measure wifi roaming performance with 802.11k (Radio Resouce Management) and 802.11r protocol amendments. My hardware setup uses the PCIe Wifi Card Compex WLE600VX with QCA9882 Chipset and ath10k_pci kernel module. Operating System is Ubuntu 15.10 with Kernel Version 4.2. With my setup 802.11r is working well with wpa_supplicant but I'm not able to get 802.11k working. As I already mentioned I'm using the ath10k kernel module with firmware version 10.2.4.45. I suppose 802.11k (RRM) is not working because it is not supported by the firmware. The reason of my guess is the following: When I looked through the ath10k source code for RRM support I found out that in the file wmi.c there are the structs - wmi_cmd_map - wmi_10x_cmd_map - wmi_10_2_4_cmd_map In the last two the function bcn_tmpl_cmdid and prb_tmpl_cmdid both are not supported (and I use firmware version 10.2.4) and these use the struct wmi_bcn_prb_info (wmi.h) which includes the rrm info. This leads me to two questions: - Am I right, that the firmware does not support 802.11k or should 802.11k be supported by the QCA9882 Chipset and the atheros firmware and kernel modules? - Are there any atheros wifi modules which were successfully tested with 802.11k? Hopefully someone can help me with this!
