tests: Bluetooth: Tester: Set controller ACL buffer size #89680
Conversation
Change the ACL buffer sizes to be a higher value than the default, as that caused some issues with the CIS established event. Signed-off-by: Emil Gydesen <[email protected]>

May be use of 27 bytes as max ACL data size exposes a bug in the Zephyr Controller? This should be easily reproducible in bsim CI tests with the hci_ipc and nrf52_bsim audio tests with 27 byte ACL configured, right?

It looks like a bug in the controller, yes, but not sure how to properly determine that yet.
I did try to run the test from #87207 which would also connect the CIS using the same BT Tester build, but at least in BSIM it doesn't seem to fail. Could be due to timing and availability of buffers?

Relates to #88300.
