ESP32 Forum

I'm trying to make ESP32 connect to AP, I''ve two different codes, one is working and the other isn't

module connects to AP when i declare the following:
wifi_config_t wifi_config_sta= {
.sta = {
.ssid = CONFIG_DEAFULT_AP_SSID,//ESP_STA_SSID,
.password = CONFIG_DEFAULT_AP_WIFI_PASSWORD//ESP_STA_PASS
},
};

module didn't connect to AP when I initialize like:
strcpy ((char*)wifi_config_sta.sta.ssid, CONFIG_DEAFULT_AP_SSID);
strcpy ((char*)wifi_config_sta.sta.password, CONFIG_DEFAULT_AP_WIFI_PASSWORD);


can anyone tell me what is the differences between this declerations?


Thank you in advance,

Not sure. Try printing the strlen of both examples and make sure they are the same length, is where I would start.

How do you declare your wifi_config_sta variable in the 2nd example?

ESP_Sprite,


This is the declaration of the wifi_config_sta variable in the second example.

wifi_config_t wifi_config_sta;

strcpy ((char*)wifi_config_sta.sta.ssid, CONFIG_DEAFULT_AP_SSID);
strcpy ((char*)wifi_config_sta.sta.password, CONFIG_DEFAULT_AP_WIFI_PASSWORD);

user_name,

This is what I did first and they are the same

ESP_Sprite,
Thank you for the hint, seems that when I declare

wifi_config_t wifi_config_sta;

the memory bloack that wifi_config_sta variable use is not 0 !!!
When I wrote:

wifi_config_t wifi_config_sta = {0};

everything work fine.


Regards,

It is recommended to use this for init:
