maybe its necesarry for you to connect your rasberry pi via android phone.
here is how
What you need.
1. wifi module
2. access to rasberry pi (via putty or direct).
3. android phone with SSH Client application installed
here is to download SSH Client application https://play.google.com/store/apps/details?id=com.anstudios.ssh&hl=en
Step by step
1. plug in wifi module to raspberry pi
2. turn on raspberry pi. enter ifconfig command, wlan0 should come up in list, but not connected to any address
pi@raspberrypi ~ $ ifconfig
wlan0 Link encap:Ethernet HWaddr
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
4. turn on wifi hotspot/tethering on your android phone
5. enter command sudo iwlist wlan0 scan | grep ESSID
pi@raspberrypi ~ $ sudo iwlist wlan0 scan | grep ESSID
ESSID:”TonkeyLINK”
ESSID:”HP-Print-41-Officejet Pro 8600″
ESSID:”xiaomi1Sganteng”
6. edit wpa_supplicant.conf
sudo nano /etc/wpa_supplicant/wpa_supplicant.conf
add this line
network={
ssid=”your essid name/copy paste from earlier scan result”
psk=”you hotspot password”
}
for example with my handphone
network={
ssid=”xiaomi1Sganteng”
psk=”ganteng”
}
7. save file, and reboot raspberry pi.
8. after reboot you’ll see that now your raspberry wlan module is connected to you hotspot. enter command sudo ifconfig wlan0 to see its ip address.
9. open SSH client on your android phone and enter raspberry pi address,
10. Now you can access your raspberry via your android phone. :D.
to restart raspberry networking you can enter this command instead rebooting raspberry
sudo /etc/init.d/networking stop
sudo /etc/init.d/networking start
