Aborting connection procedure after calling bt_conn_le_create()

[kpreiss]

We're running SDK v2.6.0 on a nrf5340 processor and initiating a connection to a specific heartrate monitor using the bt_conn_le_create() function.  What function do we call if we want to abort the scanning/connection process?  Is it sufficient to call bt_le_scan_stop()?

Thank you.

Hi,

If I remember correctly you can set a timeout when you call bt_conn_le_create(), such that if it doesn't successfully connect within a few hundred ms, then you can go back to scanning or idle state. That is the normal way of doing it. However I do believe there is an bt_conn_le_create_cancel() that can also be used here.

Hi Kenneth,

Thanks for the reply.  I could not find the function bt_conn_le_create_cancel() in any of the header files for SDK v2.6.0.

Hi Kurt,

You are right, once you have tried to establish a connection you need to use bt_conn_disconnect(), I can find from \v3.1.0\zephyr\include\zephyr\bluetooth\conn.h in the description for bt_conn_disconnect():

"Disconnect an active connection with the specified reason code or cancel pending outgoing connection."
