据我所知，这是因为当计时器过期时，传递给app_easy_timer_cancel的timer_id无效。然而，我认为添加一个检查像if(conn_timeout != EASY_TIMER_INVALID_TIMER){..就能解决这个问题。< / p > < p > 1)。有人能告诉我为什么app_easy_timer_cancel仍然执行，即使我之前检查有效性?这是在app_on_disconnect上执行的代码片段。< / p > < p > printf_string(“用户断开连接! \ n \ r”);< br / >如果(conn_timeout ! = EASY_TIMER_INVALID_TIMER) {< br / > / / < br / >取消计时器printf_string(“conn_timeout取消了由于用户断开\ n \ r”);< br / > app_easy_timer_cancel (conn_timeout); < br / >} < / p > < p > 2)。 I used the watch tool from Keil to keep an eye on the value of conn_timeout. It is 0x00 initially and stays this value if I connect and disconnect before the timer elapses. However when the timer does elapse and the callback of conn_timeout is executed, conn_timeout keeps the value 0x03. It stays at this value even if I proceed the software (after it gets stuck on ASSERT_WARNING(0) in void app_easy_timer_cancel(const timer_hnd timer_id)). Also connecting and disconnecting is still possible. Doing this ( quicker than the timer period) also does not make a change to the value 0x03.
What does this value mean? Isn't this value supposed to be reset to 0x00 when the timer elapses or when the timer is cancelled?

Kind regards,
Niek
