Hello everyone,

When I run this code :

GeSHi © Codebox Plus Extension
I got this error :
Code: [Select all] [Expand/Collapse]
  1. assertion "Invalid mbox" failed: file "C:/Users/XXXX/Desktop/esp-idf/components/lwip/lwip/src/api/tcpip.c", line 455, function: tcpip_send_msg_wait_sem
GeSHi © Codebox Plus Extension
I have no idea how to solve this problem.

Thanks you in advance.

AH.

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

Code: Select all

        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:

Code: Select all

const char *pref = "https://XXXXXXXXXXXXXXXXX.com/connect.php?texte=";
char dest[100];
... // code that defines chr
strcpy(dest, pref);
strcat(dest, chr);    // <-- NOTE do this only once

But, I get the same error. Does anyone else have a solution please ?

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 (esp-idf/examples/wifi/getting-started/station) but I didn't find the way to wait properly, could you enlighten me?

Hello Axel,
You need to use events, just as the example uses, in order to get it working.

Maybe you missed the esp_netif_init(), you can follow https://github.com/espressif/esp-idf/bl ... .c#L70-L73
