Hi i have problems with mbedtls. i am not using mbedTLS APIs directly but i am using certificated MQTT connection. I use AWS IoT Core certificates. i added them manually. Here is output of my code:

As i understand from output mbedtls. There is a problem with deallocation of certificates. When i use lower sleep time than 30 second i have no problem because MQTT client does not disconnect.

[MicroController]

Code: Select all

xTaskCreate(scd4x_read_measurements_task, ... , &sensor_data, ... );

sensor_data is local to app_main(), i.e. &sensor_data becomes invalid as soon as app_main() returns.
Do not pass a pointer to a local variable to the new task!
The new task subsequently writing to this variable will cause stack/memory corruption, which may result in any kind of unexpected and seemingly completely unrelated errors immediately or later.

thank you, problem solved i did not even realized.
