WL1271 driver to disable low power mode

Hi Dhaval,

Can you tell me which driver release?
Do you mean the elp mode?

I am not sure if you can disable it, but it would be possible to change the timeout value.

Hi Joseph,

we are using R5_SP7 driver release and i am talking about Low Power Mode disable.And what is that elp mode?Do you mean that enhanced low power mode??is both modes are same or not?

Thank You,

Dhaval Radiya.

Hi Dhaval,

Yes, both the modes are the same.
Like I said before, you can increase the elp timeout value.

To disable it, you might want to make some modification in the driver and have a debugfs exported for this. You can take a look at debugfs.c (drivers\net\wireless\wl12xx\)

Hi TI,

Thank You for your reply.

now, we are configuring wl12xx chipset for multi-role support and we follow below link steps :

http://processors.wiki.ti.com/index.php/OMAP_Wireless_Connectivity_NLCP_Multi_Role_Configuration#Configuring_AP

but after entering some command like:

Add NAT and DHCP server capability to the AP

echo 1 > /proc/sys/net/ipv4/ip_forward

udhcpd /etc/udhcpd.conf

iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE

we get below error message:

FATAL: Module ip_tables not found.
iptables v1.4.9.1: can't initialize iptables table `nat': iptables who? (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.

so any solution for that??

Thank You.

Hi Dhaval,

Please check: https://github.com/TI-ECS/build-utilites/blob/master/wlan_enable_config.sh 
and confirm if you have the same in your defconfig. Specifically: CONFIG_IP_NF_IPTABLES=y

Hi Joseph,

Thank For your reply. Now I have query about multi-Role configuration for Single channel – Station (wlan0) and AP (wlan1) works on same channel.

In that , when we change Channel=1 in hostapd.conf we got the below error message.

root@am3517-evm:~# hostapd -B /etc/hostapd.conf -P /var/run/hostapd.pid
Configuration file: /etc/hostapd.conf
[  113.737030] wl12xx: removing interface 00:00:00:00:00:02
[  113.760894] wl12xx: state: 2
Could not set channel for kernel driver
wlan1: Unable to setup interface.
[  113.825561] wl12xx: removing interface 00:00:00:00:00:02

So, can you give any suggestion??

Thank You

Dhaval.
