Hi,
This is the follow up on this question, I'm not sure how it was closed.
I'm getting different execution times (not transmission time, like mentioned in the answer here) for `bt_nus_send` function, although in the above mentioned post it is said that the function is not blocking. So, I'm wondering why sometimes the function takes a couple of milliseconds to execute if it is not blocking.
In most cases it is stable, and around ~100 microseconds, but I think when there is a problem with connection, I get a couple of milliseconds. If the function only queues data in the SoftDevice controller's FIFO for transmission in the next connection event, I expect similar execution times each time the function is called.
What could be the cause of the problem?
