Ethernet:-

• Make ethernet_bw.sh file.
• Copy below code snippet in file.

[code lang=”bash”]
#!/bin/sh
INTERVAL=”1″ # update interval in seconds
while true
do
R1=`cat /sys/class/net/eth0/statistics/rx_bytes`
T1=`cat /sys/class/net/eth0/statistics/tx_bytes`
sleep $INTERVAL
R2=`cat /sys/class/net/eth0/statistics/rx_bytes`
T2=`cat /sys/class/net/eth0/statistics/tx_bytes`
TBPS=`expr $T2 – $T1`
RBPS=`expr $R2 – $R1`
TKBPS=`expr $TBPS / 1024`
RKBPS=`expr $RBPS / 1024`
echo “TX eth0: $TKBPS kB/s RX eth0: $RKBPS kB/s”
done
[/code]

• Push ethernet_bw.sh file to Android device through ADB and start script.

WiFi :-

• Make wifi_bw.sh file.
• Copy below code snippet in file.

[code lang=”bash”]
#!/bin/sh
INTERVAL=”1″ # update interval in seconds
while true
do
R1=`cat /sys/class/net/wlan0/statistics/rx_bytes`
T1=`cat /sys/class/net/wlan0/statistics/tx_bytes`
sleep $INTERVAL
R2=`cat /sys/class/net/wlan0/statistics/rx_bytes`
T2=`cat /sys/class/net/wlan0/statistics/tx_bytes`
TBPS=`expr $T2 – $T1`
RBPS=`expr $R2 – $R1`
TKBPS=`expr $TBPS / 1024`
RKBPS=`expr $RBPS / 1024`
echo “TX eth0: $TKBPS kB/s RX eth0: $RKBPS kB/s”
done
[/code]
