In range test, the RSSI is helpful to check attenuation of cable and align difference between environments. Since data packets can be transmitted with different rate and power, the RSSI of all packets can be variant. Oppositely beacon is transmitted with the same rate and power, so beacon RSSI will be relatively invariant, and more helpful to diagnose problems. The output of beacon RSSI in unit of dBm looks like: Beacon: 19 (-33 dBm), TF: 0 Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> --- drivers/net/wireless/realtek/rtw89/core.c | 3 +++ drivers/net/wireless/realtek/rtw89/core.h | 1 + drivers/net/wireless/realtek/rtw89/debug.c | 7 +++++-- drivers/net/wireless/realtek/rtw89/phy.c | 2 ++ 4 files changed, 11 insertions(+), 2 deletions(-)
