[SOLVED]New router does not work with RTOS sdk

[masacate]

Hi, I have been using the last Espressif RTOS SDK (august 2015)without problem, I have replace my router (other model) and in theory everything is the same. Since this moment I are not able to connect to the WIFI using the RTOS version, I can connect without problem using AT. Some suggestions please...???

thanks in advance

Hi,

Here is an example of connecting to router http://bbs.espressif.com/viewtopic.php?f=31&t=228

Please notice to set "stationConf.bssid_set = 0;"

If your problem is still unsolved, you could provide your test code and UART logs, we will help debugging it.

Hi, I have added "stationConf.bssid_set = 0;" to my RTOS program and the problem continue. I have also used the program you indicated viewtopic.php?f=31&t=228 and there is no problem. It seems to occur only with RTOS programs I use.
It happens even with the simple example program without any special code in the tasks:

sprintf(config->ssid, "myWIFI");
sprintf(config->password, "myPassword");
//need not mac address
config->bssid_set = 0;


/* need to sure that you are in station mode first,
* otherwise it will be failed. */
wifi_station_set_config(config);
free(config);
}

xTaskCreate(task2, "tsk2", 256, NULL, 2, NULL);
xTaskCreate(task3, "tsk3", 256, NULL, 2, NULL);
}

My debug log says that is continuosly trying to reconnect because of some problem:

please some advice?

Masacate the difference is not your router but the wireless security you used. In older router you would have used WEP and in new one WPA.

With the recent esp_iot_rtos master 1.2.0 the wifi station mode with WPA is broken. I will post a issue on the git now. For now you can set your wireless security to wep and use the chip

Solved with the new release ESP8266 SDK RTOS 1.4
thanks

Looking at your code I am confused by the task implementations. It seems you are performing:

Code: Select all

while(1) {
}


tight loops. Surely if one of those tasks gets control it will never release it since I understand that the FreeRTOS is not preemptive ...?

[masacate]

This is simply a naked sample to see that the problem was the connection with the router and to avoid any uncertainty about some possible programming bugs.
