Compilation Errors with the latest ESP32 package, v2.x works #7

Closed Bush-cat closed 3 weeks ago

Bush-cat commented 1 month ago

I didn't look into it so much and simply rolled back ESP32 package from v3.0.5 to v2.17. A notice in the README or an update would be nice.

esp_mqtt_client_config_t changed between esp-idf 4.x and 5.0

the latest version causes lots of errors:

The Problem was, this Repo was not updated, the Example in the Library got an Update where ESP32 Package v3 is supported and the Example was updated but only the Azure_IoT_Central_ESP32 and not the Azure_IoT_Central_ESP32_AzureIoTKit https://github.com/Azure/azure-sdk-for-c-arduino/commit/28acdc59b6ac095dd827a0f3d33793930f52e798
