Use it like this:
bool ICACHE_FLASH_ATTR auth_data_callback(const char* username, const char *password, struct espconn *pesp_conn){
Serial.print("username is: ");
Serial.println(username);
if ((String)username == "root" && (String)password == "admin" ) {
return true;
}else{
return false;
}
}
void setup()
{
...
MQTT_server_onAuth(auth_data_callback);
}
The espconn parameter is a pointer to the TCP connection state. Definition is included via "interface.h". You can get the address and port of the client via this. Not needed if you only want to do username/password auth.
the /* we can ignore this */ parameter is in the data callback (it is a pointer to the client data structure - not really useful for the user code, I use this in my other project esp_mqtt).

Hi,
Case I need to access "struct espconn *pesp_conn" param, to check ip, userdata,... how can I do it? I'm getting error "invalid type struct..."
Thanks in advance,

I'm on vacation, so I can't test it, but I think, you will need this include from the SDK:
