Hi,
Followed the below steps to connect a tablet and my device
iw phy `ls /sys/class/ieee80211/` interface add p2p0 type managed
wpa_supplicant -B -u -iwlan0 -c/etc/wpa_supplicant.conf -N -ip2p0 -c/etc/p2p_supplicant.conf -u
wpa_cli -ip2p0
p2p_group_add
Quit and follow below steps in the device
echo 1 > /proc/sys/net/ipv4/ip_forward ip addr add 192.168.0.1/24 dev p2p-p2p0-0 udhcpd /etc/udhcpd.conf iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
Now i am connecting the tablet with the ssid and passphrase which is displayed along with p2p_group_add. The connection is successful but it doesnt get
IP address. The tablet keeps displaying the optaining ip address.
What would be the problem? It was working fine till yesterday but today I updated the software and it stopped working.
wpa_supplicant.conf
##### wpa_supplicant configuration file template #####
#
# This option can be used to allow wpa_supplicant to overwrite configuration
# file whenever configuration is changed (e.g., new network block is added with
# wpa_cli or wpa_gui, or a password is changed). This is required for
# wpa_cli/wpa_gui to be able to store the configuration changes permanently.
# Please note that overwriting configuration file will remove the comments from
# it.

ctrl_interface=/var/run/wpa_supplicant
# IEEE 802.1X/EAPOL version
# wpa_supplicant is implemented based on IEEE Std 802.1X-2004 which defines
# EAPOL version 2. However, there are many APs that do not handle the new
# version number correctly (they seem to drop the frames completely). In order
# to make wpa_supplicant interoperate with these APs, the version number is set
# to 1 by default. This configuration value can be used to set it to the new
# version (2).
eapol_version=1
# AP scanning/selection
# By default, wpa_supplicant requests driver to perform AP scanning and then
# uses the scan results to select a suitable AP. Another alternative is to
# allow the driver to take care of AP scanning and selection and use
# wpa_supplicant just to process EAPOL frames based on IEEE 802.11 association
# information from the driver.
# 1: wpa_supplicant initiates scanning and AP selection; if no APs matching to
# the currently enabled networks are found, a new network (IBSS or AP mode
# operation) may be initialized (if configured) (default)
# 0: driver takes care of scanning, AP selection, and IEEE 802.11 association
# parameters (e.g., WPA IE generation); this mode can also be used with
# non-WPA drivers when using IEEE 802.1X mode; do not try to associate with
# APs (i.e., external program needs to control association). This mode must
# also be used when using wired Ethernet drivers.
# 2: like 0, but associate with APs using security policy and SSID (but not
# BSSID); this can be used, e.g., with ndiswrapper and NDIS drivers to
# enable operation with hidden SSIDs and optimized roaming; in this mode,
# the network blocks in the configuration file are tried one by one until
# the driver reports successful association; each network block should have
# explicit security policy (i.e., only one option in the lists) for
# key_mgmt, pairwise, group, proto variables
# When using IBSS or AP mode, ap_scan=2 mode can force the new network to be
# created immediately regardless of scan results. ap_scan=1 mode will first try
# to scan for existing networks and only if no matches with the enabled
# networks are found, a new IBSS or AP mode network is created.
ap_scan=1
# EAP fast re-authentication
# By default, fast re-authentication is enabled for all EAP methods that
# support it. This variable can be used to disable fast re-authentication.
# Normally, there is no need to disable this.
