Description

How to call airkiss function? for example "airkiss_version".When compiled, Arduino IDE print"undefined reference to `airkiss_version'.
I have found the airkiss.h in "Arduino\hardware\espressif\esp8266\tools\sdk\include"
also the libairkiss.a in "Arduino\hardware\espressif\esp8266\tools\sdk\lib"

• Access functionality from the Espressif ESP8266 SDK
• This example code is in the public domain
• This is for advanced users.
• Note that this makes your code dependent on the ESP8266, which is generally
• a bad idea. So you should try to use esp8266/Arduino functionality
• where possible instead, in order to abstract away the hardware dependency.

// Expose Espressif SDK functionality - wrapped in ifdef so that it still
// compiles on other platforms
#ifdef ESP8266
extern "C" {
#include "user_interface.h"
#include "airkiss.h"

#endif

void setup() {
Serial.begin(115200);

void loop() {
// Call Espressif SDK functionality - wrapped in ifdef so that it still

#ifdef ESP8266
Serial.print("wifi_station_get_hostname: ");
Serial.println(wifi_station_get_hostname());

I had found the problem .when linking ,Arduoino esp8266 just links the smartconfig lib ,not the airkiss lib.

Linking everything together...

maybe it would help changing the topic to reflect the problem with linking process, so it gets picked up (attention) by relevant person.
