描述
Issue template
- Hardware description: STM32E407 development board
- RTOS: FreeRTOS
- Installation type: micro_ros_setup
- Version or commit hash: foxy
Steps to reproduce the issue
- Add multiple subscribers and publishers in the system.
- Use high frequency msg
- Too long time in callbcak
Expected behavior
All subscribers should be able to enter their callback functions when there are publishers in the system.
Actual behavior
When using only subscribers, everything works fine. However, when adding publishers to the system, some subscribers cannot enter their callback functions. (This problem also occurs when I don't set up a publisher and receive topic messages at a high frequency)The following solutions have been attempted but did not fully resolve the issue:
- Reduce the size of publishers and messages. With this approach, some improvement was observed, but still, not all messages could be received. Of the three subscribers set up, only one or two would be able to enter their callback functions.
- Change the publisher to "best effort" mode. However, when the publisher is adjusted to "best effort" mode, the topic cannot be received in ROS.
- Use Trigger. When Trigger is set to accept all messages or to enter the callback only when a specific message is received, none of the subscriber's callback functions can be entered.

研究方向
在搭載 FreeRTOS 和 Foxy 的 STM32E407 開發板上，使用提供的 app.c 重現環境開始測試，並使用多個高頻 publisher 和 subscriber。檢查 executor 設定以及 localization_estimate_callback、chassis_report_callback、trajectory_callback 和 timer callbacks，包括它們的時序和訊息大小。完成的標準是找出回呼在負載下停止進入的原因，並驗證所有 subscriber 仍持續接收訊息。
