Hi Guys,
What a nice board this MKR1000.  Do you know this board has a Wi-Fi Sniffer Mode?   You just have to call m2m_wifi_enable_monitoring_mode(...).  But that my problem. I receive a loader error:

"TestMKR.ino:34: undefined reference to `m2m_wifi_enable_monitoring_mode'
collect2.exe: error: ld returned 1 exit status
exit status 1
Error compiling for board Arduino/Genuino MKR1000."

My Code is here:

#define CONF_MGMT  // need for tenum type
#include <WiFi101.h>
extern "C" {
#include "driver/include/m2m_wifi.h"
#include "driver/include/m2m_types.h"
/* Declare receive buffer */
uint8 gmgmt[1600];
/* Callback functions */
static void wifi_event_cb(uint8 u8WiFiEvent, void * pvMsg) {
// Soemthing here to do
/* Call back monitoring */
static void wifi_monitoring_cb(tstrM2MWifiRxPacketInfo *pstrWifiRxPacket,
                      uint8                   *pu8Payload,
                      uint16                  u16PayloadSize) {
 // Something here to do
void setup() {
while (!Serial) delay(10);
// Mon Call Back
tstrWifiInitParam param = tstrWifiInitParam();
param.pfAppWifiCb = wifi_event_cb;
param.pfAppMonCb  = wifi_monitoring_cb;

if(!m2m_wifi_init(&param)) {
  tstrM2MWifiMonitorModeCtrl strMonitorCtrl = tstrM2MWifiMonitorModeCtrl();
  /* Enable Monitor Mode with filter to receive all data frames on channel 1 */
  strMonitorCtrl.u8ChannelID = 1;
  strMonitorCtrl.u8FrameType = DATA_BASICTYPE;
  strMonitorCtrl.u8FrameSubtype = M2M_WIFI_FRAME_SUB_TYPE_ANY;
  sint8 rsl = m2m_wifi_enable_monitoring_mode(&strMonitorCtrl, gmgmt, sizeof(gmgmt), 0);

void loop() {

It seems that something is missing on a WiFi101 Winc1500 module to link this function with my code.
If I change: m2m_wifi_enable_monitoring_mode(&strMonitorCtrl, gmgmt, sizeof(gmgmt), 0); for
I received a compilation error saying to less parameters.

If I replace m2m_wifi_enable_monitoring_mode(&strMonitorCtrl, gmgmt, sizeof(gmgmt), 0); with
I do not received any link(ld) error.

This function m2m_wifi_disable_monitoring_mode() is also missing.  

I was able to run every example we get with WiFi101 library.  Is there an other library like Winc1500 I should use?

This function m2m_wifi_send_wlan_pkt(...) also is missing.  

In m2m_wifi.c Line 60, I uncommitted #define CONF_MGMT and it seems ok now.

Any Idea?


Hi - i know this is a really old topic, but today I was working on the same thing and I have encountered the exact same problem. Did you find a way around this? I'm trying to use the function "m2m_wifi_enable_monitoring_mode" and its throwing the error about that its an undefined function.

I would really appreciate hearing what you did about this.
