Wifi direct - Ping not succesful - (AM335x + WL18xx + linux)

Johncy Bennette

Hi,

I am following the instruction in the below site to connect to Wifi direct (Create Autonomous 1:2 P2P Group (Push button Control).

http://processors.wiki.ti.com/index.php/WiFi_Direct_Configuration_Scripts#p2p_find

Setup I use:

I have a AM335x evaluation module with WL18xx WiFi module and OS is linux.

I have my board similar to AM335x evaluation module with WL18xx WiFi module and OS is linux. My board is configuered as Group owner. EVM board is configured to be client.

I assign the ip address using DHCP. My board gets the IP 192.168.0.1 and EVM board gets the ip as 192.168.0.20

ping 192.168.0.20 from my board is not successful.

ping 192.168.01 from EVM board is not successful.

But if I run the dhcpd server in th EVM board and dhcpc in my board, then ping is successful

Any thoughts is highly appreciated.

Regards,

Johncy.

Hi Johncy,

Are both the EVMs running the same software (driver/firmware/kernel)?
Can you share the dhcp conf file that you are using?

Hi Gigi,

My udhcpd.conf file:

# Sample udhcpd configuration file (/etc/udhcpd.conf)
# The start and end of the IP lease block
start 		192.168.0.20	#default: 192.168.0.20
end		192.168.0.254	#default: 192.168.0.254
# The interface that udhcpd will use
interface   p2p-p2p0-0		#default: eth0
#Examles
opt	dns	8.8.8.8  8.8.4.4 # public google dns servers
option	subnet	255.255.255.0
opt	router	192.168.0.1
option	lease	864000		# 10 days of

Followed http://processors.wiki.ti.com/index.php/WiFi_Direct_Configuration_Scripts#p2p_find -- (Create Autonomous 1:2 P2P Group (Push button Control), DHCP to assign ip address).

I will post the driver/firmware version tomorrow.

Hi Gigi,

I used ip command to set the ip address in the server side and the netmask is set as 255.255.255.255 and I changed it as 255.255.255.0 I am able to ping each other now.
