Hello,

I've a "simple" question : Is it possible for an ESP32 to use mobile data (4G internet connection not Wifi) from a smartphone by connecting it via Bluetooth?
A bit like the BluFi API already does but not for a Wi-Fi network.

Thanks in advance,

AH.

Note that esp_wifi_connect() only *starts* a connection attempt, and will return more-or-loss immediately; the connection isn't actually created at that time. Suggest you check e.g. the examples in esp-idf to see how to properly wait until it is.


Thanks for your answer, I looked at what you ...

Why are you concatenating `chr` to `dest` twice?

printf(strcat(dest, chr)); // <-- here
esp_http_client_config_t config = {
.url = strcat(dest, chr) // <-- here
};

It's also not a good idea to concatenate to a literal string. Rather, you should do something like this:

const char *pref ...

Hello everyone,

When I run this code :

#include <stdio.h>
#include <string.h>

#include "esp_vfs_fat.h"
#include "esp_wifi.h"

Are you trying to do something similar to this thread?

I found a solution that seems to fit:


#include <stdio.h>
#include <string.h>
#include "esp_system.h"
#include "esp_console.h"

Hi,

You need to use the console approach. See this example:

First of all, thank you so much for your response! I looked at what you sent me, I may be blind but I don't really see how it helps me with my problem ...

Hello,

I am a new user on esp-idf. I have done some tests after following the "Getting Started" section, including this one:


#include <stdio.h>

void app_main(void)
{
char chr;
printf("Enter Data : ");
scanf("%c", &chr);
printf("Data entered : %c.", chr);
}


Everything goes well, I start ...
