4.4.6 Installation in Wi-Fi Direct Mode (With NL80211 Support only for Kernel v3.8 or higher)
The steps for installing OneBox-Mobile software in Wi-Fi Direct Mode are as follows:
The "start_p2p_nl80211.sh" script present in the "release" folder needs to be run in order to start the supplicant and also
for installing the Wi-Fi Direct mode. The configurable parameters in the p2p_nl80211.conf file are outlined below:
• listen channel
• operating channel
• GO Intent
wpa_supplicant version used should be latest one (2.6 or higher). Please check the start_p2p_nl80211.sh script for better
understanding and update it accordingly.
After starting the supplicant, the p2p_commands mentioned below should be executed.
• To find other P2P networks
#. /wpa_cli –i wifi0 p2p_find
• To find other P2P devices in range
#. /wpa_cli –i wifi0 p2p_peers
• To connect to a P2P network
#. /wpa_cli –i wifi0 p2p_connect <BSS ID> pbc go_intent=<intent value>
Here the intent value range is between 0 and 15 (Putting intent value to 0 makes p2p device as client and 15 makes p2p
device as group owner). If you are becoming GO, dhcp server should be running on GO Interface.
4.4.6.1 Autonomous GO Mode
The steps for installing OneBox-Mobile software in Wi-Fi Direct Mode are as follows:
The "start_p2pgo.sh" script present in the "release" folder needs to be run in order to start the supplicant and also for
installing the Wi-Fi Direct mode. The configurable parameters in the p2p_nl80211.conf file are outlined below:
• listen channel
• operating channel
• GO Intent
wpa_supplicant version used should be latest one (2.6 or higher). Please check the start_p2pgo.sh script for better
understanding and update it accordingly.
The given below command is used to start the device in Autonomous GO mode:
# ./wpa_cli –i wifi0 p2p_group_add freq=<channel_freq>
The "channel_freq" input mentioned in the above command is the center frequency of the Wi-Fi channel in which the GO
needs to be started The OneBox-Mobile software supports DFS slave mode. However, DFS Channels need to be avoided
till the module is certified for DFS.. If this parameter is not provided, then the GO will start in the channel specified in the
p2p_nl80211.conf file.
