I don't think we flush as much as possible. I believe the LL command should have more priority and use different buffer from the TX buffer. What I believe is if the TX buffer is not queued for the current packet, it won't be queued anymore. And the TX buffer will be flushed after the connection is terminated.

@Elias Simon: I don't see any problem that endnode comment on your question and suggest an answer. As far as I understand, this is a community where members helping each other. Without the help of the active users, such as Endnode, RK, etc, we won't be able to handle all of the questions.

We have voting system and "accepting answer" feature, so that the correct information/answer will stand out.

No, there is nothing like that in the API. The only thing I can think of to flush the TX queue, is to trigger a disconnection to avoid queued packet being sent. And there is no guarantee all packets in the buffer will be stopped right after we call disconnect request.

OK, no problem. It's also not answer but comment as you can see.

Dude, you're not a Nordic employee, so can you please try to stick to questions that you can answer with testable suggestions? With this, like my last question, I simply don't believe you because you don't have the credibility of being paid to know this stuff.

Nothing like that in the API, only connection procedure seems can be canceled but not GATT methods queued in the SD...
