4 months ago I think i figured it out, the command structure issue was probably caused by the following commit not being merged right. https://github.com/FreeRTOS/iot-reference-esp32c3/commit/f4fe11e27a7d686b7a2f22de278ece570b692ce9
And the frequent PINGREQ by the LAST_PACKET_RX_TIME always being 0. but why. Why is it never set anywhere in the code? Shouldn't a PUBACK trigger the LAST_PACKET_RX_TIME to be set correctly?
And btw the KeepAliveInterval doesn't do anything unless it's lower than the TX_TIMEOUT, effectively always setting it to 30 seconds.
Is all this by design or am I missing something here?

I've used the temp_sub_pub_led_control as a starting point. everything is basically unchanged. when its running, it publishes like normal and after 20-30 seconds starts sending PINGREQ every 2 seconds or so. No matter how I change the keep alive interval, i get the same problem. After 2-3 hours of this, i get a crash of MQTTcore saying no command structure available.
