hello, is there a solution? I have the same problem.

ftylitak commented 2 years ago

Even though this is quite old, just for future reference, this issue is caused because you try to use this library with esp-idf 4.x which is not supported based on my tests (or ESP32 Arduino 2.x).

Switch back to esp-idf 3.x (3.3.6 is the newest at the time of writing).

If you are using Arduino code and Arduino IDE, you need to go to the Boards Manager and downgrade esp32 support to maximum version 1.0.6.

A very rough workaround is to comment out all the following lines:

https://github.com/VSChina/ESP32_AzureIoT_Arduino/blob/0c090d0832b165078fbe877012e4cf62f42aeb24/src/az_iot/c-utility/pal/socket_async.c#L128-L152

and replace them by:

result = sock;

May be it is a timing issue. Sounds bad not to check for the socket connect return code...though it works for me with esp-idf v4.4.

FYI: at some point I changed all the backend of this project with an updated version of az_iot based on https://github.com/Azure/azure-iot-sdk-c (commit: cb8ef0535ebd06f81231be4c40b372ef17cd995e)

Just in case someone is blocked and it can help.

This worked for me, thank you!
