1. I see. In this case you will have to be careful with what is happening in `send_message`, it should not have any blocking behavior, etc. 2. Yes, the second...

2. This is possible, but it depends on the implemention of `send_message`, it should not do anything you cannot do in interrupts. E.g. it should not rely on freertos tasks,...

I think we can consider the initial question/issue resolved/responded to. Feel free to reopen if there is anything that we still need to resolve on the IDF side of things

Yes, the callback is called from a task with `ESP_TASK_TIMER_PRIO`, so there could be tasks with a higher priority (e.g. BT) > 会停止运行一段时间 How long is 一段时间? Is the callback...
