ESP32 with aws-iot-device-sdk-embedded-C - Shadow EventHandler doesn't work

[andreasb]

Hi,

I have an Esp32 to control different sensors. To change data like the temperature, I have an Alexa Skill with shadow function.

That works for a while without problems. Since 2 month, the shadow event handler don't work correctly anymore.

The connection to aws works, and the debugger tell, me, that the EventHandler are registerd. Sometime it works normal and sometimes I get no changings from aws.

I use ESP-MDF and the esp-aws-iot project.

Has anyone already had similar problems and can give me a tip?
