As mentioned, the connection interval. It determines how frequently both sides in the bluetooth link will wake up to exchange packets https://github.com/zephyrproject-rtos/zephyr/blob/c906d4a1039b857b56556f00e4abf0eb9afc8e7e/include/zephyr/bluetooth/conn.h#L42-L63

3.5.4.6 LE asynchronous connection (LE ACL)
The LE asynchronous connection (LE ACL) logical transport is used to carry LL and
L2CAP control signaling and best effort asynchronous user data. The LE ACL logical
transport uses a 1-bit NESN/SN scheme to provide simple channel reliability. Every
active Peripheral has one LE ACL logical transport to the piconet Central, known as the
default LE ACL.
 

7.8.12 LE Create Connection command

If the local device is already connected to the same device address as the advertiser
(including two different Resolvable Private Addresses that resolve to the same IRK),
then the Controller shall return an error which should use the error code Connection
Already Exists (0x0B).

Could you try changing the connection parameters (connection interval) instead?

Hi Justin,

There is the multiple advertising sample from nRF Connect SDK which shows how to configure and run two advertising sets simultaneously. But only one is connectable while the other is non-connectable. So I am a bit skeptical about whether your use case might be possible. I will discuss this internally with the team and get back to you.

In the meantime please do checkout the sample.

Regards,

Priyanka
