RTL系列模组
4 RTL 系列模组
4.1 RF 测试环境搭建
4.1.1 驱动配置
为了支持RF test 工具的使用，必须配置RTL 系列的驱动。
Device Drivers > Network device support > Wireless LAN
<M> Realtek 8189F SDIO WiFi
<M> Realtek 8723D SDIO or SPI WiFi
4.1.2 Tina 配置
按如下方法配置ETF 工具。
Utilities > rf test tool >
<*> realtek-rftest.......realtek rf test tools
rtk_hciattach >
<*> rtk_hciattach.........Realtek BT HCI UART initialization tools
4.2 rtwpriv 测试命令
4.2.1 传导TX 测试
ifconfig wlan0 up
# Enable Device for MP operation
rtwpriv wlan0 mp_start
# enter MP mode
rtwpriv wlan0 mp_channel 7
# set channel to 1 . 2, 3, 4~13 etc.now is channel 7
rtwpriv wlan0 mp_bandwidth 40M=0,shortGI=0
# set 20M mode and long GI；set 40M is 40M=1.
rtwpriv wlan0 mp_ant_tx a
# Select antenna A for operation
if device have 2x2 antennam select antenna "a" or "b" and "ab" for operation.
rtwpriv wlan0 mp_txpower patha=44
# set path A and path B Tx power level , the Range is 0~63.
rtwpriv wlan0 mp_rate 135
# set OFDM data rate to 54Mbps,ex: CCK 1M = 2, CCK 5.5M = 11 ;
OFDM 6M=12、54M = 108 ;
N Rate: MCS0 = 128, MCS1 = 129 MCS 2=130....MCS15 = 143 etc.
rtwpriv wlan0 mp_ctx count=%100,pkt
# start continuous Packet Tx
rtwpriv wlan0 mp_ctx stop
#stop continuous Tx
rtwpriv wlan0 mp_stop
# exit MP mode
ifconfig wlan0 down
# close WLAN interface
4.2.2 传导RX 测试
ifconfig wlan0 up
# Enable Device for MP operation
rtwpriv wlan0 mp_start
# Enter MP mode
rtwpriv wlan0 mp_channel 13
# Set channel to 1 . 2, 3, 4~13 etc.
rtwpriv wlan0 mp_bandwidth 40M=0,shortGI=0
# Set 20M mode and long GI or set to 40M is 40M=1.
rtwpriv wlan0 mp_ant_rx a
# Select antenna A for operation
if device have 2x2 antennam select antenna "a" or "b" and "ab" for operation.
rtwpriv wlan0 mp_arx start
# start air Rx teseting.
rtwpriv wlan0 mp_arx phy
# get the statistics.
rtwpriv wlan0 mp_reset_stats
#Stop air Rx test and show the Statistics / Reset Counter.
rtwpriv wlan0 mp_arx stop or rtwpriv wlan0 mp_reset_stats
rtwpriv wlan0 mp_stop
# exit MP mode
ifconfig wlan0 down
# close WLAN interface
