WiFi w/ dynamic credentials

[ankyankyanky]

I’m trying to figure out how to connect to an AP with credentials read from the flash storage. I’m new in C and is pretty much living on what is written in the examples. Unfortunately, all the examples are setting up WiFi with a wifi_config_t struct initialised with preprocessor directives like:

Code: Select all

wifi_config_t wifi_config = {
	.sta = {
		.ssid = EXAMPLE_ESP_WIFI_SSID,
		.password = EXAMPLE_ESP_WIFI_PASS
	},
};

How do I change this code to operate with non hardcoded values? I’ve tried to initialise with variables, and changing wifi_config with dot notation and strcpy but have been unsuccessful so far.

I think you are heading in the right lines. The wifi_config struct does have to be populated. If I remember correctly, the struct has fields called ssid and password. Both of these are arrays. What that means is that you have to copy in your desired SSID and Password.

Here is a loose example:

Code: Select all

char *ssid = "mySsid";
chat *password = "mypassword";

wifi_config_t wifi_config;
memset(wifi_config, 0, sizeof(wifi_config);
strcpy(wifi_config.sta.ssid, ssid);
strcpy(wifi_config.sta.password, password);
... rest of logic

Notice that the variables "ssid" and "password" contain your desired values which could have been read from NVS (Non volatile storage).
