We are experimenting using CARL9170. Firmware Release:"1.9.6"
The VIF is in 'Managed mode' we want to receive data packets of other stations destined to a DS, and get it in the MAC reveive path.
For example, In monitor mode, the VIF receives all packets, by sniffing in the medium & allows all packets of other stations being sent to AP, and deliver it to the upper layers. We want to receive all packets(of other Destination address) in managed mode,
Is it possible to sniff packets in Managed mode. where in data packets sent by other stations are also received?
Although I tried couple of things in Firmware & Carl9170, I coudn't achieve the result.
1.In ::carlfw/usb/main.c,
void handle_usb(void)
++ set(AR9170_MAC_REG_SNIFFER, 1); //added this line to enable sniffing in Managed mode
2. In ::carlfw/src/wlanrx.c
void handle_wlan_rx(void)
-- if (!(wlan_rx_filter(desc) & fw.wlan.rx_filter)) //changed this line to
++ if( 1 )
In carl9170 module, source code,
In fine mac.c
int carl9170_set_operating_mode(struct ar9170 *ar)
-- carl9170_regwrite(AR9170_MAC_REG_SNIFFER, sniffer);
++ carl9170_regwrite(AR9170_MAC_REG_SNIFFER, sniffer | AR9170_MAC_SNIFFER_ENABLE_PROMISC );
In order to achieve this, what changes in firmware/ Carl9170 module needs to be done?
Thanks
Mani
