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 told me...

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 = "https://XX...

Hi, You need to use the console approach. See this example: https://github.com/espressif/esp-idf/tree/master/examples/system/console/basic 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. It did h...

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 the monitor w...
