How to configure hostapd.conf for wps push button?

Question

I have android6.0.1 I want to enable the wps when hotspot on.

Can anyone give some ideas and give whatever changes i want to do in someother files.?

Can anyone provide any application for wps server.?

Thanks, VinothS,

Funny coincidence. I was looking for this, too, today for Debian. Currently I'm following:

http://ftp.netbsd.org/pub/NetBSD/NetBSD-current/src/external/bsd/wpa/dist/hostapd/README-WPS and a bit of https://w1.fi/cgit/hostap/plain/hostapd/hostapd.conf

I just needed to copy these lines:

wpa_psk_file=/home/<username>/etc/hostapd/hostapd.psk
ctrl_interface=/var/run/hostapd
eap_server=1
wps_state=2
ap_setup_locked=1
wps_pin_requests=/var/run/hostapd.pin-req
device_name=USB2.0 WLAN
manufacturer=ATHEROS
model_name=WAP
model_number=123
serial_number=12345
device_type=6-0050F204-1
os_version=01020300
config_methods=label display push_button keypad

into my hostapd.conf file. I created a custom one for myself in ~/etc/hostapd.conf, but normally there is one in /etc/hostapd/hostapd.conf. In your case you might have to change device_type. I tried to mostly verify the information like manufacturer, ... but I don't think they are that important. I was able to find manufacturer and serial number using lsusb and then sudo lsusb -v -s 5:7 (the numbers after -s are the bus and device numbers shown by lsusb)

After that I restarted hostapd with the new configuration file:

sudo pkill hostapd
sudo bash -c "nohup hostapd '$HOME/etc/hostapd/hostapd.conf' > '$HOME/nohupHostapd.out'" &

and did a quick sudo hostapd_cli wps_pbc and then was able to connect the printer using WPS.

Needs to add the string (wps_state, eap_server) in the following files,

system/netd/server/SoftapController.cpp

int SoftapController::setSoftap(int argc, char *argv[]) {
int hidden  = 0;
int channel = AP_CHANNEL_DEFAULT;

int wps_state = 2;

if (argc < 5) {
  ALOGE("Softap set is missing arguments. Please use:");
  ALOGE("softap <wlan iface> <SSID> <hidden/broadcast> <channel> <wpa2?-psk|open> <passphrase>");
  return ResponseCode: : CommandSyntaxError;
}

if (!strcasecmp(argv[4], "hidden"))
  hidden = 1;

if (argc >= 5) {
  channel = atoi(argv[5]);
if (channel <= 0)
  channel = AP_CHANNEL_DEFAULT;
}

std::string wbuf(StringPrintf("interface=%s\n"
  "driver=nl80211\n"
  "ctrl_interface=/data/misc/wifi/hostapd\n"
  "ssid=%s\n"
  "channel=%d\n"
  "ieee80211n=1\n"
  "hw_mode=%c\n"
  "ignore_broadcast_ssid=%d, eap_server = 1, wps_state = %d\n",
  argv[2], argv[3], channel, (channel <= 14) ? 'g' : 'a', hidden,wps_state));

std::string fbuf;
if (argc > 7) {
char psk_str[2*SHA256_DIGEST_LENGTH+1];
if (!strcmp(argv[6], "wpa-psk")) {
  if (!generatePsk(argv[3], argv[7], psk_str)) {
    return ResponseCode: : OperationFailed;
  }
  fbuf = StringPrintf("%swpa=3\nwpa_pairwise=TKIP CCMP\nwpa_psk=%s\n", wbuf.c_str(), psk_str);
  } else if (!strcmp(argv[6], "wpa2-psk")) {
    if (!generatePsk(argv[3], argv[7], psk_str)) {
      return ResponseCode: : OperationFailed;
    }
    fbuf = StringPrintf("%swpa=2\nrsn_pairwise=CCMP\nwpa_psk=%s\n", wbuf.c_str(), psk_str);
  } else if (!strcmp(argv[6], "open")) {
    fbuf = wbuf;
  }
} else if (argc > 6) {
  if (!strcmp(argv[6], "open")) {
    fbuf = wbuf;
  }
} else {
  fbuf = wbuf;
}

if (!WriteStringToFile(fbuf, HOSTAPD_CONF_FILE, 0660, AID_SYSTEM, AID_WIFI)) {
ALOGE("Cannot write to \"%s\": %s", HOSTAPD_CONF_FILE, strerror(errno));
  return ResponseCode::OperationFailed;
} else {
  return ResponseCode::SoftapStatusResult;
}

Testing,

hostapd_cli wps_pbc
