Description
## Issue template
- Hardware description:
ESP32-C6-WROOM-1
- Installation type:
espidf, component - ESP-IDF 5.5v
- Version or commit hash:
Humble
#### Steps to reproduce the issue
I have tested the publisher and subscriber from [this repository](https://github.com/micro-ROS/micro_ros_espidf_component/tree/humble/examples/int32_sub_pub) and found that the subscription_callback is never called. On the other hand, the publisher works fine, even with a multithreaded subscriber.
Could anyone help point out any possible issues that might be causing this problem?

Research direction
Start by running examples/int32_sub_pub on the ESP32-C6 with ESP-IDF 5.5 and the Humble component version reported here. Read the example's subscription setup and callback execution path, then compare it with the working publisher behavior. Done means the subscriber reliably invokes subscription_callback and the reproduction or fix is documented.
